Introduction  
Congratulations on your purchase of this precision component and thank you for selecting  
Parasound.Your new AVC-2500 Audio Video Controller is designed to be the heart of the finest  
imaginable home theater system and to provide you with years of listening and viewing  
enjoyment. Intuitive front panel and remote control operation makes yourAVC-2500 one of the  
easiest to use high performance audio/video products ever developed.  
Autoformat Surround Processing (ASP) modes include Dolby Digital, DTS, Stereo, a dual-  
stereo “party” mode, an enhanced music mode and mono. You can easily set up the AVC-2500  
to detect the type of signal present at each input and automatically decode it based on how the  
source software was originally encoded. Your AVC-2500 also has discrete 5.1 channel analog  
inputs to accommodate the latest processing technology and the possibility of future formats.  
The AVC-2500 has unique features you have never seen before on any audio equipment.  
Therefore, we strongly advise you take the time to read these instructions thoroughly; you will  
need them to fully understand and appreciate its extensive and unprecedented capabilities.  
About this Manual  
The names of connectors and controls are italicized to help you find what you are looking for  
within a particular section. On-screen and front panel display indications are in small caps and  
the variable settings or adjustments shown in the displays are bracketed. The drawings on the  
following pages are intended as a quick reference guide to explain controls and connectors.  
Unpacking and Inspection  
Carefully unpack your AVC-2500 Audio Video Controller and locate the enclosed accessories:  
Universal remote control with 4 AAA batteries  
Detachable AC cord  
Omnidirectional calibration microphone with cord and AA battery  
FM Folded Dipole 300 Antenna  
FM 300 ohm to 75 "balun" matching transformer  
Threaded DIN to F type 75 coax FM antenna adapter  
AM loop antenna  
(2) 3.5 mm mini plugs for 12V triggers  
Be sure to carefully inspect the AVC-2500 for any signs of shipping damage. If you believe you  
notice any, contact your Parasound Dealer immediately. Be sure to save both cartons and the packing  
inserts for future transport and always pack the carton into a larger protective outer carton before  
shipment.  
Placement of Your AVC-2500  
Install your AVC-2500 near your source equipment so you can use the shortest possible  
interconnect cables. Keep your AVC-2500 out of direct sunlight because it could interfere with  
the remote control sensor.You should also keep the unit away from heat sources such as hot air  
ducts, radiators and moisture sources such as open windows.  
Optional Rack Mounting Kit  
If you want to rack mount your AVC-2500, you will need to obtain the optional RMK-3 rack  
mount kit. When you install the RMK-3 onto the AVC-2500 and remove its four feet, it will  
occupy three rack spaces (5 1/4 inches high) in a standard 19” wide equipment rack. Refer to  
the RMK-3 instructions for installation procedures. Make certain to use the eight insulated  
shoulder washers included with the RMK-3 to prevent metal-to-metal contact between its brackets  
and your equipment rack.

Making Connections toYour AVC-2500  
Precautions  
Before making any connections to your AVC-2500, be sure to turn off the power to your  
amplifiers. When connecting cables to theAVC-2500, make sure there is no strain or tension  
on any connections that could cause them to pull loose later.  
Rear Panel Connections  
There are ninety-three connectors and terminals on the rear panel! To make installation and  
the instructions easier to follow, discussion about connections are organized in a clockwise  
direction from the left side to the right side of the rear panel and also by functional groups  
for analog audio, video, digital audio, antenna, special control interface, and AC cord.  
References to specific connectors on the AVC-2500 are usually italicized.  
Analog Audio/Video 1-6 Input Connections  
All six Audio/Video analog inputs are compatible with typical line level sources such as  
DVD players, videocassette recorders, satellite receivers, tabletop cable converter boxes,  
etc. Each of the sixAudio/Video inputs also switches an accompanying NTSC/PAL composite  
video or S-video input. You can also assign either of the two Component Video inputs and  
any of the eight Digital audio inputs to accompany these six Audio/Video inputs. You may  
also connect the left and right analog audio outputs of your audio/video source components  
to these input.  
Video 6 Input and Record (Record and Playback) Connections  
Use the Video 6 inputs and outputs for the VCR you intend to use to record the picture and  
sound. The signal present at the Video 6 Record output sends analog audio from whichever  
of the other five Audio/Video or six Audio-only inputs you select.  
1. Connect the left and right audio output connectors from the VCR you’ll use for recording  
to the Video 6 Input connectors of the AVC-2500.  
2. Connect the left and right Video 6 Record Output connectors of the AVC-2500 to the left  
and right audio input connectors of the VCR.  
3. Connect the composite video output connector of your VCR to the Video 6 input of the  
AVC-2500 and connect the Video 6 Composite Record Output connectors of the AVC-  
2500 composite video input connectors of the VCR.  
Zone Audio and Video Output Connections  
The AVC-2500 has stereo audio and NTSC/Pal composite video output connections for  
independent remote zone operation. This feature allows you to route any of the sources  
connected to theAVC-2500 to both the main zone (Main) and a separate remote zone (Zone).  
You can view or listen to different or same sources in the main and remote zones  
simultaneously. Connect the left and right Zone Audio Outputs to your remote zone power  
amplifier and connect the Zone Composite Video output to your remote zone video monitor.  
Note: The remote zone cannot access digital signals. Therefore, you must connect the analog  
outputs of your components to the analog inputs inputs in order to access them from the  
remote zone.  
Analog Audio 1-6 Input Connections  
The six audio-only analog inputs are compatible with typical analog line level sources such  
as CD players, MiniDisc players, cassette decks, etc. Connect the left and right analog audio  
outputs of your audio/video source components to these inputs. You can also “assign” any  
of the eight Digital audio inputs to accompany any of the six Audio analog inputs.  
17  
 
5.1 Analog Inputs  
The 5.1 Analog Input jacks are designed to accept up to six channels of processed analog  
output from a DVD player or other component with discrete outputs. Connect the six discrete  
outputs of your source component to the corresponding 5.1 Analog Input jacks of the AVC-  
2500. Note:You will need an optional module to control volume from the 5.1 analog inputs.  
Othewise, you should use the volume control on your DVD player if so equipped.  
Audio Only Record Output Connections  
The audio signal from the source you selected for the main zone is routed to both pairs of  
Record Output connectors. Connect the left and right play/output of your tape deck to the  
left and right of any of theAVC-2500’s Audio 1-Audio 6 input connectors. Next, connect the  
left and right audio record/input connectors of your tape deck to either pair of Left and Right  
channel Record Output connectors of your AVC-2500.  
Front Left and Right Channel Outputs  
Connect the Left and Right Front channel outputs of your AVC-2500 to either the inputs of  
a two channel amplifier or to two channels of a multi-channel amplifier that are then connected  
to your main front left and right (L, R) speakers.  
Center Channel Output  
Connect the Center channel output of yourAVC-2500 to the input of a mono amplifier or to  
the channel of the multi-channel amplifier that is connected to your center (C) speaker.  
Left and Right Surround Channel Outputs  
Connect the Left and Right Surround output jacks of yourAVC-2500 to the inputs of the two  
channel amplifier or to two channels of a multi-channel amplifier that are connected to your  
left and right surround (LS, RS) speakers.  
Subwoofer Output Connections  
Two Subwoofer output jacks are provided for your convenience if you have two subwoofers.  
For passive subwoofers without built-in amplifiers, connect the Left and/or Right Sub outputs  
of your AVC-2500 to the input(s) of the amplifier channel(s) that are connected to your  
passive subwoofer(s). For powered subwoofers with built-in amplifiers, connect the Left  
and Right Sub outputs of your AVC-2500 to the left and right line inputs of your subwoofer.  
If your subwoofer has only one input jack, you can use either the Left or Right outputs of the  
AVC-2500 since both send the same monaural information. We recommend that you switch  
off the crossover on your subwoofer amp and use the 24 dB per octave low pass filter of the  
AVC-2500. If your sub doesn’t have a bypass switch for its crossover, adjust it to the highest  
frequency setting.  
AC Line Cord Connection  
The rear panel mounted IEC standardAC receptacle accepts theAC cord supplied with your  
AVC-2500. We recommend the use of an AC line filter to protect the AVC-2500 against  
potentially damaging line surges and voltage fluctuations. Plug the female end of the AC  
cord firmly into the rear mounted AC receptacle and make sure that it is properly seated,  
then connect the male end to an uninterrupted AC power line.  
Main External Remote Control  
The Main External IR allows for remote control operation via a wired infrared repeater  
system or system controller when infrared commands cannot directly reach the front panel  
infrared receiver. The input connector accepts a standard 1/8-inch (3.5 mm) two conductor  
mini plug. The tip is positive and the sleeve is negative. Your Authorized Parasound Dealer  
or Custom Installer can recommend a compatible infrared repeater system for the AVC-  
2500. Connect the output of an infrared repeater system to the Main IR input.  
18  
 
Zone External Remote Control  
The Zone External IR allows for control of the AVC-2500 from a remote zone. The input  
connector accepts a standard 1/8-inch (3.5 mm) two conductor mini plug. (The tip is positive  
and the sleeve is negative). Your Authorized Parasound Dealer or Custom Installer can  
recommend a compatible infrared repeater system for theAVC-2500. Connect the output of  
an infrared repeater system to the Zone IR input.  
Main DC Trigger (Labeled DC Trigger 1 on some units)  
This jack provides a +12 Volt DC trigger voltage to activate equipment that can be triggered  
with DC voltage such as power amplifiers, relays, motorized projection screen, fans, lights,  
or other components. Connect the Main (or 1) DC Trigger output of the AVC-2500 to the  
DC input of the component you want to activate. The DC trigger delivers up to 350 mA of  
current. The Main (or 1) DC Trigger accepts a standard 1/8 inch (3.5 mm) two conductor  
mini plug. The tip is positive and the sleeve is negative. You can program the AVC-2500 to  
activate the Main DC Trigger in response to turning on the AVC-2500 or to a button stroke  
on its remote control. Refer to the Setup section for details on programming the Main (or 1)  
DC Trigger.  
Zone DC Trigger (Labeled DC Trigger 2 on some units)  
This jack provides a +12 Volt DC trigger voltage to activate equipment that can be triggered  
with DC voltage such as power amplifiers, relays, motorized projection screen, fans, lights,  
or other components. Connect the Zone (or 2) DC Trigger output of the AVC-2500 to the  
DC input of the component you want to activate. The DC trigger delivers up to 350 mA of  
current. The Zone (or 2) DC Trigger accepts a standard 1/8 inch (3.5 mm) two conductor  
mini plug. The tip is positive and the sleeve is negative. You can program the AVC-2500 to  
activate the Zone DC Trigger in response to turning on the AVC-2500 from a remote zone,  
or to a button stroke on its remote control. Refer to the Setup section for details on  
programming the Zone (or 2) DC Trigger.  
Important Note  
The two DC Trigger jacks and the two External Remote jacks are the same size, despite their  
different functions. The DC Trigger jacks have small rubber plugs inserted into them to help  
you avoid accidentally damaging your infrared repeater system by plugging it into a live  
12V DC jack. Don’t remove a rubber plug until you are ready to plug in a DC trigger  
connection.  
Audio Trigger  
This connector provides a fixed level L + R monaural audio signal to activate equipment  
such as power amplifiers, audio sensing power strips, or other components that can be  
triggered with an audio signal. The Audio Trigger accepts a standard 1/8-inch (3.5 mm) two  
conductor mini plug. The tip carries the signal and the sleeve is ground. Connect the Audio  
Trigger output of the AVC-2500 to the audio sensing input of the component you want to  
activate.  
Digital Recording Output Connections  
To record through either of these digital output connectors, select the digital source you  
want to record on the front panel or remote control. The AVC-2500 simultaneously routes  
the digital bitstream to both the Coax and Optical Toslink output connectors. Connect either  
the Optical or the 75 Coax Digital Record Output connectors of the AVC-2500 to the  
digital record input of your digital recorder.You may also wish to refer to the owner’s manual  
of your digital recorder.  
19  
 
Antenna Connections  
You will not be able to receive any radio stations unless you connect FM and AM antennas  
to the AVC-2500. The following are options to connect FM and AM antennas:  
FM Dipole Antenna  
A standard FM “folded dipole” 300 wire antenna is included with your AVC-2500. This  
dipole antenna is adequate for most urban and suburban locations. Connect the spade lugs  
of the dipole antenna to the two screw terminals on the included small “balun” matching  
transformer. Press the balun over the female 75 connector of the rear panel of your AVC-  
2500. Next, spread out the antenna and hang it on the wall or the back of the equipment  
cabinet. Experiment with the direction and placement of the dipole antenna to obtain the  
best reception.  
75 Coaxial Antenna  
TheAVC-2500 has a standard DIN-type 75 connector with a push-on coaxial FM antenna  
plug. An adapter is included to accommodate the threaded F-type connectors that are used  
in North America.  
Outdoor Roof Antenna  
For best reception and maximum noise rejection, we recommend the use of a high-quality  
outdoor FM antenna. The additional stations you can receive and the superior sound quality  
will make the extra effort worthwhile. Connect the outdoor antenna with a 75 coaxial  
cable directly to the 75 FM Antenna Input of the AVC-2500. If you use 300 twin lead,  
connect the two bare wire leads to the included “balun” adapter and press it onto the female  
75 coaxial FM antenna input connector.  
Cable TV and Community Antenna  
In many situations, you may be able to use the FM antenna output of a cable TV or a  
community antenna jack. These connect in the same way as an outdoor antenna.  
AM Antenna  
A molded plastic loop antenna is supplied with your AVC-2500. Connect the two wires of  
the AM loop antenna to the posts labeled AM and GND. Position the loop antenna for best  
AM reception. If you are trying to pick up very distant stations, you may connect a single  
long wire to the AM terminal and a good earth ground to the GND terminal.  
RS 232 Control  
The RS-232 External Control port is the interface for connecting one of the many software  
based system controllers such as AMX, Phast, or Creston. This 9-pin serial port provides  
two-way communication for control and status feedback from the AVC-2500. Contact your  
Parasound Dealer or Custom Installer for more information regarding interfacing an external  
control system to your AVC-2500.  
Component Video Connections  
Each Component Video Input and the ComponentVideo Output includes three separate jacks.  
Separating the video signal components of luminance (Y) and the color difference (Cb and  
Cr) delivers the very highest quality video reproduction. Not every source or monitor labels  
its component video Y, Cb, Cr. Equivalent labeling for component video connections may  
be Y, B-Y R-Y or Y, PB, PR. Refer to the owner’s manual of your video component for  
details.  
20  
 
Outputs  
Connect the Component Video Monitor Output connectors of your AVC-2500 to the  
corresponding input connectors of your video line processor or directly to your monitor or  
projector.You can select whether the on-screen display will appear at the Component Video  
Output connectors during the setup process. Refer to the setup section for more details  
about assigning the on-screen display to the component video output.  
Inputs  
Connect the component video outputs of your DVD player to the corresponding Component  
Video Input connectors of the AVC-2500. Once you have connected the component video  
sources to the inputs of theAVC-2500, you will need to assign the component video sources  
to any of the six Audio/Video Inputs. Refer to the setup instructions for component video  
assignment procedures.  
Digital Audio Input Connections  
Your AVC-2500 has eight digital input connections: four Coax RCA jacks, two Optical  
Toslinks, one AES/EBU XLR connector, and an Ext RF 8 pin connector for an optional  
Parasound RFD-1 demodulator. You may use the digital output of a source component in  
conjunction with its own analog output or that of another source component. Once you have  
connected the digital output of your source component to one of the Digital Inputs of the  
AVC-2500, you can assign that Digital input to be selected simultaneously with any of the  
six Audio/Video or six Audio-only sources. Refer to the setup instructions for Digital Input  
assignment procedures. Use only cables intended for digital signal transmission.  
Coaxial Digital Inputs  
The four Coax Inputs on theAVC-2500 accept a standard S/PDIF digital bitstream from any  
CD player, DVD player, DSS receiver, or other digital component equipped with a 75 Ω  
coaxial output. Connect the coaxial output of your digital source to any of the Coax Inputs  
using an interconnect cable designed for this application.  
Fiber-OpticToslink Input Connections  
Each of the two fiber-optic Toslink inputs on theAVC-2500 accept a standard S/PDIF digital  
bitstream from any CD player, DVD player, laserdisc player, DSS receiver, or other digital  
component equipped with a Toslink optical output. Connect the optical output of your digital  
source to either of the Optical Inputs using a Toslink fiber optic cable.  
AES/EBU 110 Balanced Input Connection  
The AES/EBU (Audio Engineering Society/European Broadcast Union) 110 balanced  
connection is the standard for professional digital audio equipment and high-end consumer  
digital equipment because of its inherent noise rejection capability. Connect the AES/EBU  
output of your CD transport, or other digital source to the Digital AES/EBU input.  
External RF Demodulator  
To decode Dolby Digital encoded laser discs, you will need to purchase and connect the  
optional Parasound RFD-1 RF demodulator between the External RF Demodulator input  
and the RF or AC-3 RF output jack of your laser disc player. Use a 75 cable with an RCA  
plug on each end to connect your RFD-1 to your laser disc player.

Composite and S-Video Monitor Output Connections  
If your video monitor or projector is equipped with separate input connections and switching  
for NTSC/PAL composite video, S-video, and component video, you can connect all three  
video formats to the AVC-2500’s corresponding Composite Video, S-Video or Component  
Video Output connectors. Note that the AVC-2500 can convert S-video input signals to  
composite video output signals, but it does not convert from composite video to S-video,  
nor to or from component video.  
Both composite video and S-video have a choice of output connectors that include or exclude  
the on-screen display (OSD) information. This feature gives you the option of sending the  
output with on-screen display capability to a separate monitor or to the picture-in-picture  
input of your monitor instead of having the on-screen display superimposed over the picture  
in your main monitor or projector screen.  
S-Video and Composite Video Input Connections  
Each of the sixAudio/Video inputs has both composite and S-video connectors with separate  
video circuits and amplifiers. TheAVC-2500 can only convert video signals from S-video to  
composite video, but not vice versa. For example, when you connect a video signal to one of  
the six composite RCA input jacks, the video signal will only be available through the RCA  
composite Monitor and Record output jacks.  
AVC-2500 Front Panel Controls and Auto Cal Mic Connection  
We designed the AVC-2500 user interface to be simple and intuitive, so we avoided  
unnecessary front panel controls and indicators that tend to make operation confusing. During  
setup, you will have the opportunity to program many typical functions and operations into  
memory for easy subsequent control of your AVC-2500.  
On-Off Button  
Press the On-Off button to turn the unit on and off. When you turn on the AVC-2500, the on-  
screen display and front panel displays show you the status of the settings that were made  
before the unit was last turned off. The items displayed are the Input Source, Digital Input,  
Surround Mode, and Volume Level. If the tuner was selected, the frequency and preset num-  
ber are displayed. The on-screen display will turn off about four seconds after the AVC-  
2500 is turned on.  
Infrared Receiver  
Infrared signals from the remote control are received through the infrared receiving eye.  
Volume Control - Rotary Knob  
The large round Rotary Knob normally controls volume for all channels. You can adjust  
volume up and down in 1 dB steps by turning this knob. It also serves as the rotary selector  
for Surround Modes, Digital Inputs, Tuner Presets, and Input Sources. When you press any  
of the 4 buttons marked Surround, Digital, Preset, or Source, its corresponding blue LED  
will light for about 5 seconds, during which time the Rotary Knob is available for making  
that selection. Five seconds after making your selection, the rotary knob resumes master  
volume control. If you want the knob to revert to volume control without waiting five seconds,  
simply press the same selector button again.  
Source Button  
Pressing the Source button once temporarily converts the Rotary Knob from controlling  
volume to become the Input Source Selector. Its blue LED will stay lit for five seconds  
during which time you can choose any of the six Audio/Video or six Audio-only sources.  
The rotary knob is available for this function only while this LED is on. If you want the knob  
to revert to volume control without waiting five seconds, press the Source button again.  
22  
 
Preset Button  
Pressing the Preset button once automatically selects the tuner, even if a different source  
was already selected. It temporarily converts the knob from controlling volume to become  
the Preset Selector for the stations that were stored into the 20 possible memory presets. Its  
blue LED will stay lit for five seconds during which time the rotary knob is available for  
selecting presets. If you want the knob to revert to volume control without waiting five  
seconds, press the Preset button again.  
Digital Button  
Pressing the Digital button once temporarily converts the knob from controlling volume to  
become the Digital Input Selector. Its blue LED will stay lit for five seconds during which  
time you can choose any of the eight digital inputs, the 5.1 channel analog input, or return to  
analog. If you want the knob to revert to volume control without waiting five seconds, press  
the Digital button again.  
Surround Button  
Pressing the Surround button once temporarily converts the knob from controlling volume  
to become the Surround Mode Selector. Its blue LED will stay lit for five seconds during  
which time you can choose any of the five ASP modes. If you want the knob to revert to  
volume control without waiting five seconds, press the Surround button again.  
Surround Mode Indicators  
These indicators let you know the type of digital bitstream the AVC-2500 has detected and  
how it is being decoded.  
DTS indicator  
The blue DTS indicator illuminates when the AVC-2500 has detected a DTS bitstream,  
regardless of which ASP mode you have selected.  
Dolby Digital  
The blue Dolby Digital indicator illuminates when theAVC-2500 has automatically detected  
a Dolby Digital bitstream, regardless of which ASP mode you have selected.  
Pro Logic Indicator  
The blue Pro Logic indicator illuminates when theAVC-2500 has automatically detected an  
analog, PCM, or 2/0 Dolby Digital signal. However, Pro Logic processing is only available  
in the Cinema ASP mode.  
Overload Indicator  
The red Overload indicator will illuminate when any of the internal analog-to-digital  
converters are being overloaded. This only occurs when an unusually high output analog  
source is selected. TheAVC-2500 monitors the extent and duration of the signal overload to  
determine the optimum signal level applied to the A/D converters. If this indicator flashes,  
the AVC-2500 will attenuate the signal just until the internal analog-to-digital converters  
are no longer overdriven and the overload indicator stops flashing. This new level will remain  
while the source is playing so there are not audible volume fluctuations.You can also manually  
adjust the input level to the analog to digital converters in the setup menu.  
23  
 
Automatic Calibration Microphone Input Connection  
The front panel Cal Mic jack is for the ACM-2500 Automatic Calibration Microphone that  
is used for automatic calibration of individual channel levels and delay times. Plug theACM-

Autoformat Surround Processing Modes (ASP)  
Your AVC-2500 automatically detects the type of digital signal present at the chosen digital  
input and will decode it based upon the Autoformat Surround Processing (ASP) mode you  
have selected for that input. This advanced feature takes the guesswork out of selecting the  
correct surround mode every time you play a different source. Source components transmit  
their signals in two channelAnalog, Pulse Code Modulation (PCM), Dolby Digital, or DTS.  
Cinema Mode  
Dolby Digital  
Dolby Digital delivers six totally separate (discrete) channels of sound. Like Dolby Surround  
Pro Logic, it includes Left, Center and Right channels across the front of the room. Dolby  
Surround Pro Logic provides a single limited-bandwidth (100 Hz to 7,000 Hz) surround  
channel that is typically played back in the home through two-channels of amplification and  
two surround speakers. In comparison, Dolby Digital provides separate (discrete) center,  
left surround and right surround channels, for more precise localization of sounds and a  
more convincing, realistic ambience. The sixth channel, the Low Frequency Effects Channel  
(LFE), contains additional bass information to maximize the impact of scenes with special  
effects such as explosions, crashes, etc. The LFE channel frequency response is 3 Hz to 120  
Hz. All six channels in a Dolby Digital system are digital, and the AVC-2500 can transfer  
them without loss from the producer’s mixing console to your home system.  
While in the CinemaASP mode, theAVC-2500 automatically decodes Dolby Digital encoded  
source material. If the material was encoded in Dolby Digital 5.1, theAVC-2500 plays back  
all six channels independently. If the material was encoded in Dolby Digital 3/2 or 2/0, the  
AVC-2500 automatically switches to Dolby Surround Pro Logic.  
DTS  
Like Dolby Digital, DTS Digital Surround is an encode/decode system that delivers six  
channels (5.1) of high-quality audio. The Digital Theater Surround (DTS) surround format  
lets you enjoy up to 6 discrete channels of digital surround sound from most laser disc  
players but only DVD players that are equipped with DTS output capability. Six independent  
channels of DTS material are played back when the Cinema ASP mode is selected and a  
DTS signal is present.  
Choosing the Cinema ASP mode for DTS music playback is not recommended because it  
may accentuate the bass in DTS music discs.  
Two-channel PCM  
PCM encoded material is found on compact discs and laser discs digital outputs. In the  
CinemaAutoformat Surround mode, theAVC-2500 automatically decodes two-channel PCM  
material into Dolby Pro Logic Surround .  
Analog Audio  
Two-channel analog material is typically found on VCR tapes and the analog outputs of  
DVD players and cassette decks. In the CinemaAutoformat Surround mode, the AVC-2500  
automatically decodes two-channel analog audio into Dolby Pro Logic Surround.  
29  
 
THX Cinema  
By pressing the THX button on the remote control or on the front panel, you can activate the  
advanced Home THX Ultra enhancements listed below. The AVC-2500 is among the very  
few AV Controllers designed and qualified for THX Ultra Certification. Films that have  
been encoded in Dolby Digital, DTS, Dolby Pro Logic, Stereo or even Mono can all benefit  
from activating THX Ultra technologies. THX should be selected when watching movies  
that were mixed primarily for playback in large movie theater environments in which speakers  
are always mounted behind the screen. THX engineers developed patented technologies to  
accurately translate the sound from the movie theater environment into the home, correcting  
for significant tonal and spatial discrepancies between these environments. When the THX  
mode is selected on the AVC-2500, the decoded signal is modified with the following THX  
Ultra features:  
THX Re-Equalization  
The tonal balance of a film soundtrack may be excessively bright and harsh when played  
back over audio equipment in the home because film soundtracks were designed to be played  
back in large movie theaters using very different professional equipment. Re-Equalization  
restores the correct tonal balance of a film soundtrack in a small home environment.  
THXTimbre Matching  
The human ear changes our perception of a sound depending on the direction from which  
the sound is coming. Large movie theaters must use arrays of speakers to provide surround  
information for everyone in the audience. In a home theater, you need only two surround  
speakers located at the sides of your head. The Timbre Matching feature filters the information  
going to the surround speakers so that they more closely match the tonal characteristics of  
the sound coming from the front speakers. This ensures seamless panning between the front  
and surround speakers and an uninterrupted sense of spaciousness.  
THX Adaptive Decorrelation  
In a movie theater, there is always a large distance from your seat to the speakers. In a home  
theater there are usually only two surround speakers that are usually located close to your  
listening position.Adaptive Decorrelation slightly changes one surround channel’s time and  
phase relationship with respect to the other surround channel. This has the effect of expanding  
the apparent size of your room and broadens your listening position to simulate the same  
spacious surround experience as in a movie theater, but with only two surround speakers.  
THX Bass Limiter  
This THX feature prevents distortion and possible damage to the woofers in your speakers  
or subwoofer. Details about the Bass Limiter are in the Setup section.  
Music Mode  
Dolby Digital  
While in the MusicASP mode, theAVC-2500 automatically decodes Dolby Digital encoded  
source material. If the material was encoded in Dolby Digital 5.1, the AVC-2500 plays back  
all six channels independently. If the material was encoded in Dolby Digital 3/1 or 2/0, the  
AVC-2500 downmixes the signal to Pro Logic Surround.  
DTS  
In the MusicASP mode, theAVC-2500 automatically decodes DTS encoded source material.  
Since DTS is always encoded in 5.1, the AVC-2500 will play back all six channels while in  
the Music mode. Choose this mode for DTS music discs. Choosing the Music mode for  
DTS movies is not recommended because bass response may be attenuated.  
30  
 
Two-channel PCM  
PCM encoded material is found on compact discs and laserdiscs. In the Music ASP mode,  
theAVC-2500 plays back audio in the left, center, and right channels. Proprietary ambiance  
effects are routed to the surround channels. The subwoofer is active in this mode.  
Analog Audio  
Two-channel analog material is typically found on VCR tapes and the analog outputs of  
DVD players and cassette decks. In the Music ASP mode, the AVC-2500 plays back two-  
channel audio in the left, center, and right channels. Proprietary ambiance effects are routed  
to the surround channels. The subwoofer is active in this mode.  
Party Mode  
Dolby Digital  
While in the Party ASP mode, the AVC-2500 automatically decodes Dolby Digital encoded  
source material. Even if the material was encoded in Dolby Digital 5.1, theAVC-2500 plays  
back downmixed two-channel in the front left and right and rear surround channels in a  
“dual-stereo” configuration. The subwoofer is active in this mode. This mode is a great  
choice for a party because guests standing near the surround speakers will hear downmixed  
stereo rather than ambient surround effects. The center speaker is defeated in this mode.  
DTS  
In the PartyASP mode, theAVC-2500 automatically decodes DTS encoded source material.  
DTS is always encoded in 5.1, but theAVC-2500 plays back downmixed two-channel in the  
front left, right and rear surround channels in a “dual-stereo” configuration. The subwoofer  
is active in this mode.  
Two-channel PCM  
PCM encoded material is found on compact discs and laser discs. In the Party ASP mode,  
the AVC-2500 plays back downmixed two-channel audio in the front left, right and rear  
surround channels in a “dual-stereo” configuration. The subwoofer is active in this mode.  
Analog Audio  
Two-channel analog material is typically found on VCR tapes and the analog outputs of  
DVD players and cassette decks. In the Party ASP mode, the AVC-2500 plays back two-  
channel audio in the front left, right and rear surround channels in a “dual-stereo”  
configuration. The subwoofer is active in this mode.  
Mono Mode  
Dolby Digital  
While in the Mono ASP mode, the AVC-2500 automatically downmixes the signal from  
Dolby Digital, DTS, PCM or Analog monaurally to the center channel. All other channels  
are inoperative in the Mono ASP mode.  
Stereo Mode  
Dolby Digital  
While in the StereoASP mode, theAVC-2500 automatically decodes Dolby Digital encoded  
source material. Even if the material was encoded in Dolby Digital 5.1, the AVC-2500  
downmixes all information from all the channels to play two-channel audio in the left and  
right channels. The subwoofer is active in this mode.  
31  
 
DTS  
In the StereoASP mode, theAVC-2500 automatically decodes DTS encoded source material.  
TheAVC-2500 plays back downmixed two-channel audio in the left and right channels. The  
subwoofer is active in this mode  
Two-channel PCM  
PCM encoded material is found on compact discs and laser discs. In the Stereo ASP mode,  
the AVC-2500 automatically decodes two-channel PCM material to two-channel stereo.  
The subwoofer is active in this mode.  
Analog Audio  
Two-channel analog material is typically found on VCR tapes and the analog outputs of  
DVD players and cassette decks. In the Stereo ASP mode, the AVC-2500 plays back two-  
channel stereo. The subwoofer is active in this mode.

Placement ofYour Home Theater Speakers  
Speaker Placement  
Proper speaker placement is essential for optimum performance of your home theater sys-  
tem. The following are basic guidelines for speaker placement based upon idealized condi-  
tions. You may need to make placement compromises to allow for room shape, furniture  
placement, windows, doorways, and other considerations. TheAVC-2500 permits electronic  
compensation when asymmetrical speaker placement is required.  
Front Speakers  
Try to locate your front left and right speakers an equal distance to the right and left of your  
monitor or projection screen. Ideally, your listening position should be at one point of an  
equilateral triangle with the left and right speakers at the other two points. To achieve what  
is commonly called the “sweet spot,” your left and right speakers might sound better facing  
forward or slightly toed-in, depending on their dispersion characteristics, room reflections,  
and the number of people in the room.  
Center Speaker  
The center speaker’s main function is to reproduce most of the cinema dialog and blend the  
sonic image from your speakers with the visual image on the screen. It is best to place your  
center speaker directly above or below the monitor, as close to the same height as the left  
and right speakers as possible. Be sure your center speaker is shielded to prevent discoloration  
of the picture tube. If you have a projection screen that is perforated to allow sound to pass  
through, you should locate the center speaker behind the screen at the same vertical plane as  
the left and right speakers. The distance from your preferred listening position to the center  
channel speaker should be the same as the distance from your listening position to the left  
and right speakers. You can accomplish this by measuring the distance to a left or right  
speaker and locating the center speaker as far behind the plane of the left and right speakers  
as required to be the same distance. If you can’t move your center channel behind the plane  
of the left and right speakers, you can compensate for its shorter distance electronically  
during setup. The purpose of physical placement or electronic adjustment assures the sound  
from all three front speakers will arrive at your listening position at precisely the same time.  
Conventional Surround Speakers  
Surround speaker placement is a little more flexible than the front speakers are. Although  
5.1 channel processing offers discrete surround channel information, movie soundtracks  
use the surround channels more for creating an ambient effect than for defining precise  
sonic images. To avoid drawing your attention from the action on the screen and enhance  
the blend of sound and picture, you should not be able to localize the sound coming from  
your surround speakers except momentarily during certain special effects. Therefore, you  
should try to avoid pointing the surround speakers directly toward your listening position  
and place them behind you and above your ear level when you are seated. You should be  
prepared to experiment with surround speaker placement for optimum results.  
Dipole Surround Speakers  
If you are using front and rear firing dipole surround speakers, locate them above and to the  
sides of your listening area. This deliberately places you in the “null” of the dipole speakers  
to minimize localization of the surround speakers. Refer to the owner’s manual of your  
speakers for further information in locating dipole speakers.  
33  
 
Subwoofer  
Because of their long wavelengths, low bass frequencies are critically dependent on room  
placement to avoid bass-robbing standing waves or null points. Sometimes moving a  
subwoofer a few inches makes the difference between thin, weak bass and room shaking,  
foundation-rattling bass. One of the most reliable methods to correctly position your  
subwoofer is to first hook it up and place it next to your favorite listening position.  
While it is playing music or a movie with strong bass in it, slowly walk around the various  
room locations where the sub could be located.You should be able to find a place where you  
hear balanced bass without excessive boominess. Once you have found this optimum loca-  
tion, simply move the subwoofer there. If you change your listening position, you should  
repeat this procedure. If you are unable to place the sub where it sounds best, you might  
improve its sound by turning the sub’s cabinet to one side or the other. The AVC-2500 has  
two subwoofer outputs, in case you prefer two smaller subs in place of one large sub, or if  
you have an insatiable (but certainly understandable) desire for intense bass. However note  
that positioning two subs for ideal response is more challenging than positioning one, be-  
cause they will interact with each other as well as with your room.

Setting up your AVC 2500  
The AVC-2500 will work without any initial setup, so you may enjoy it right out of the box.  
However, there are eight levels of setup procedures that you can perform one at a time or all  
at once to assure easy operation and future enjoyment. Your remote control is required for  
all setup procedures. We have pre-programmed several of the default settings to make the  
AVC-2500 as ready to “plug and play” as possible. The chart on the previous indicates all of  
the settings that are pre-programmed as “defaults,” as well as for the setup options of the  
AVC-2500.  
Basic and Complete Setup Menus  
To make the setup process easier, we have segregated the setup menus into basic and complete  
categories. The basic setup menu is actually an abbreviated version of the complete setup  
menu. In most cases, the basic setup menu is more than adequate for most day-to-day  
operation. The complete menu provides access to more advanced setup operations such as  
DC trigger assignment, turning the on-screen display on or off, and resetting factory defaults.  
The basic setup menu is accessed by pressing and holding Setup/Trim, and the complete  
setup menu is accessed by pressing Shift then Setup/Trim. Once you have opened the complete  
menu, all levels of setup are accessible until you press Shift then Setup/Trim again or restore  
the system defaults.  
For easy identification, advanced setup options are gray highlighted in the  
following setup procedures.  
Programming Individual Input Sources  
Digital Input and ASP Mode Programming  
The first level of the setup process is to program each of the AVC-2500’s twelve input  
Sources to match its audio with one of the analog input pairs or one of the eight Digital  
Inputs.You can also program any of the five ASP modes to be matched to any of the twelve  
input Sources. For example, you may want to match Video 1 Source with audio from Digital  
Coaxial Input 1 from your DVD player, and process it in the Cinema ASP mode.  
Programming a Digital Input and ASP Mode to Source Inputs  
1. Select the source you want to program.  
2. Select the digital input you want to assign to that input source on the front panel with the  
Digital button and Rotary Knob or the Digital ̅ or ̃ buttons on the remote control.  
3. Select the ASP mode you want to assign to that input source on the front panel with the  
Surround button and Rotary Knob or the Surround ̅ or ̃ buttons on the remote control.  
4. Press Mem/Enter on the remote control or press Memory on the front panel  
5. [INPUT NAME] MEMORIZED will be appear in the front panel and on-screen displays for  
three seconds indicating that the desired Digital Input andASP mode have been assigned  
to that source.  
6. Repeat the process for as many of the twelve inputs as your source components require  
you to use.  
Setup Menu Level One - Input Source Setup  
The next steps in the setup process are to:  
1. Rename the AVC-2500’s twelve Source Inputs (if desired).  
2. Assign Component Video to the Source (if desired).  
3. Have the Source engage the rear panel DC trigger (if desired).  
4. Adjust the volume level of that Source to match the levels of the other sources (if desired).  
5. Set the input level to the analog to digital converters (if necessary).  
38  
 
Renaming Inputs  
You can rename each of AVC-2500’s twelve Source inputs (Audio/Video 1-6, Audio 1-6)  
from a built-in library of popular source component names or you can create your own  
names. For example, you can program your Audio/Video 1 Source to read DVD PLAYER,  
your Audio/Video 2 Source to read VCR 1, and your Audio 2 Source to read CASSETTE  
DECK on the front panel and on-screen displays.  
To Rename Inputs from the Built-in Library:  
1. Select the source you want to program.  
2. Press and hold the Setup/Trim button on the remote control until SOURCE SETUP appears  
on the front panel or on-screen display.  
3. Press the Tune or buttons until LABEL and the [CURRENT SOURCE NAME] appears  
in the displays.  
4. Use the Volume ̅ or ̃ buttons to scroll through the names in the menu.  
5. Stop on the name you want the input to be called.  
6. Press the Tune button to advance to the next SOURCE SETUP procedure, or press and  
hold the Setup/Trim button for three seconds to return to normal operation.  
To Create a New Name or Radio Station Call-Letters  
1. Select the source you want to program or tune to a radio station to program call letters.  
2. Press and hold the Setup/Trim button on the remote control until SOURCE SETUP appears  
on the front panel or on-screen display.  
3. Press the Tune < and > buttons until LABEL and the [CURRENT SOURCE NAME] OR PRESET  
[NUMBER] appears in the displays.  
4. Press Mem/Enter. A cursor will appear under the first letter of the current name.  
5. Use either the Volume ̅ or ̃ buttons to scroll through the alphanumeric menu.  
6. Stop on the letter or number that you want for the first character.  
7. Press the Tune and buttons to move to the next or previous character.  
8. Repeat steps 2 through 7 until you have created the new name of up to eight characters.  
9. Press Mem/Enter to store the new name.  
10. Press the Tune button to advance to the next SOURCE SETUP procedure, or press and  
hold the Setup/Trim button for three seconds to return to normal operation.  
When you create new names, you are only adding to the library of the input you were  
programming. Over-written names are not erased and will remain in the original library.  
Assigning Component Video Switching to Source Inputs  
While in Source Setup you can assign any of the six Audio/Video source inputs to receive  
its video signal from either of the two ComponentVideo inputs. TheAVC-2500 then switches  
the assigned Component Video in addition to composite and S-video. Since you can assign  
component video to any of the six Audio/Video inputs, this effectively expands the video  
switching capability from six to eight.  
To Program a Component Video Input to the Source Input:  
1. Select the source you want to program.  
2. Press and hold the Setup/Trim button on the remote control until SOURCE SETUP appears  
on the front panel or on-screen display.  
3. Press the Tune or buttons until COMP VIDEO: YES OR NO appears in the displays.  
4. Use either the Volume ̅ or ̃ buttons to choose between INPUT 1, INPUT 2, OR NONE.  
5. Press the Tune button to advance to the next SOURCE SETUP procedure, or press and  
hold the Setup/Trim button for three seconds to return to normal operation.  
39  
 
Assigning the Input Source to Activate the External DC Trigger  
You can program the input source to activate the external Main and/or Zone 12 V DC  
trigger located on the rear panel, whenever the source is selected. When programmed  
together with DC TRIGGER SETUP, you can activate the external DC trigger whenever you  
select a particular source. This feature provides automation options such as turning on  
projectors, lowering projection screens, etc.  
To assign an Input Source to Activate the External DCTrigger when selected:  
1. Select the source you want to program.  
2. Press and hold the Setup/Trim button on the remote control until SOURCE SETUP  
appears on the front panel or on-screen display.

4. Use either the Volume ̅ or ̃ buttons to register your yes and no responses.  
5. Press the Tune button to advance to the next SOURCE SETUP procedure, or press  
and hold the Setup/Trim button for three seconds to return to normal operation.  
Setting the Input Source Level  
Input level adjustment sets the signal level relative to all the other input sources. This  
adjustment allows you to match the levels between all twelve inputs so they all have the  
same apparent loudness. You can adjust the analog input level from –16 dB to + 16 dB.  
To Set the Input Source Level:  
1. Select the source you want to program.  
2. Press and hold the Setup/Trim button on the remote control until SOURCE SETUP appears  
on the front panel or on-screen display.  
3. Press the Tune or buttons until LEVEL appears in the displays.  
4. Use the Volume ̅ and ̃ buttons to adjust the Input Source level from –16 dB to + 16  
dB. The input level defaults to 0 dB. In most cases, the default level of 0 dB is an  
optimum setting.You should only need to change this level if the source component has  
an unusually high or low output.  
5. Press the Tune > button to advance to the next SOURCE SETUP procedure, or press and  
hold the Setup/Trim button for three seconds to return to normal operation.  
Analog Input Level Adjustment Procedures  
Analog Input Level Adjustment sets the incoming signal level to prevent distortion caused  
by overloading the input of the internal analog-to-digital converters. You can adjust the  
analog input level from –16 dB to + 16 dB. Even if you do not manually adjust the analog  
input level, theAVC-2500 will automatically attenuate input levels to prevent overload when  
necessary.  
To Manually Set the Input Source Level:

about 30 seconds.  
6. Press the Tune > button to advance to the next SOURCE SETUP procedure, or press and  
hold the Setup/Trim button for three seconds to return to normal operation.  
Setup Menu Level Two - Bass Management  
Bass management is designed to assure overall balanced bass response by accommodating  
many different types of speaker systems that may or may not be able to reproduce frequencies  
below 80 Hz. The Bass Management setup menu lets you configure all of your speakers to  
accept low frequencies below 80 Hz, or to filter out these frequencies and route them to your  
front speakers, or send them only to your subwoofer channels. THX certified speaker systems  
should always be set to "SMALL/THX for the left, right, center, and surround outputs.  
Additionally, there should always be a subwoofer in a THX speaker system  
To Setup Bass Management forYour Front Left and Right Speakers:

Volume ̅ or ̃ buttons to select either YES or NO.  
3. Select YES if you are using a subwoofer. Low frequency effects (LFE) are then routed to  
the subwoofer. If you have selected SMALL/THX or NONE for the Main, Center, or Surround  
speakers, frequencies below 80 Hz are also routed to the subwoofer channel.  
4. Press the Volume ̅ or ̃ buttons to select NO if you are not using a subwoofer. Low  
frequency effects (LFE) are then evenly distributed to the Main, Center, and Surround  
speakers as specified.  
5. Press the Tune button to advance to bass limiter settings, or press and hold the Setup/  
Trim button for three seconds to exit BASS MGMT SETUP and return to normal operation.  
6. For proper operation defeat the low pass crossover in your powered sub and use the crossover  
built into the AVC-2500. If your subwoofer has no switch to bypass or defeat its built in  
crossover, set it to its highest crossover frequency.  
Setting the Bass Limiter:  
With the extra low frequency content mixed into film soundtracks, especially in the LFE channel,  
it is sometimes preferable to limit overall bass energy to prevent overloading your speakers  
and/or subwoofer. The Bass Limiter is designed to protect woofers from over excursion,  
distortion, or damage. When in doubt, leave the Bass Limiter at its default 0 dB setting and use  
sensible master volume levels.  
Use caution when setting the Bass Limiter since high volume levels are required  
during this adjustment.  
1. If you are not already in the Bass Management setup menu, follow steps 1 and 2 above.  
2. Press the Tune or buttons until BASS LIMITER and 0 dB appear in the displays.  
3. Press the Mem/Enter button to engage the noise generator. The Bass Limiter is then set to  
its -55 dB maximum level.At the same time, the master volume is turned up to the maximum.  
4. Press the Volume ̅ or ̃ buttons to slowly raise the Bass Limiter level from -55 dB until  
the any of the woofers in the system start to “overload”. When this happens, you may hear  
some mechanical clattering sound or other evidence of distress. Sometimes the noises you  
hear are not produced by the subwoofer, but are objects that are vibrating or rattling.  
5. Quickly reduce the Bass Limiter level until you can no longer hear the distortion, clattering,  
or other unmusical sounds from any of the woofers in the system.  
6. The Bass Limiter is now set to its optimum level. Typical Bass Limiter settings should  
generally be around -20 dB.  
7. Press the Setup/Trim button to advance to SPEAKER LEVEL SETUP, or press and hold the  
Setup/Trim button for three seconds to exit BASS MGMT SETUP and return to normal operation.

Setup Menu Level Three - Calibrating Channel Levels  
TheAVC-2500 is equipped with advanced circuitry that automatically calibrates your home  
theater system’s individual channel levels. The easiest method to calibrate channel output  
levels and delay times in your home theater system is with Automatic Calibration. Before  
you start this procedure, make sure the battery is installed correctly in the ACM-2500  
Automatic Calibration Microphone and it is switched on, with the switch closest to the  
white dot on its housing.  
Treat the ACM-2500 Autocalibration Microphone with care and always insure that its battery  
is fresh. If you accidentally drop the microphone or use it with a weak battery, you may end up  
with incorrect speaker levels and delay times. If you store it for extended periods, remove the  
battery to prevent damage.  
To Automatically Calibrate Channel Levels:  
1. Connect the ACM-2500 Auto Calibration Microphone to the Cal Mic jack on the front  
panel.  
2. Locate the calibration mic upright at ear level at your listening position.

Manually Calibrating Channel Levels  
Manual calibration requires independent adjustment of the output level for each of the six  
channels of your AVC-2500 so that all channels have the same relative signal strength from  
your listening position. TheAVC-2500 lets you program its internal noise generator to advance  
from channel to channel automatically or manually.You also have the option of using either  
the internal noise generator or an external reference noise recording from an external source  
such as a DVD player or laser disc player.  
If you wish, you can calibrate your system with the aid of a sound pressure level (SPL)  
meter such as the Realistic Sound Level Meter (Radio Shack catalog # 33-2050). When you  
use an SPL meter for calibration, you should hold it upright directly in front of your head  
and make adjustments while you are seated in your listening position. If an SPL meter is  
unavailable, you can still adjust levels by ear with adequate results.  
To Manually Calibrate Channel Levels with the Internal Noise Generator:  
1. Press and hold the Setup/Trim button on the remote control until SOURCE SETUP appears  
on the front panel or on-screen display.  
2. Press Setup/Trim until SPEAKER LEVEL SETUP appears in the displays.  
3. Press the Mem/Enter button on the remote control once until the noise generator engages.  
4. After three seconds the noise generator automatically will advance to the next channel  
in the order of L, C, R, LS, RS, and Sub.  
5. Press Volume ̅ or ̃ buttons to adjust individual channels to 75 dB on an SPL meter.  
(Make sure the meter is set to C weighting and slow response time.) The noise generator  
will not advance to the next channel until you are finished setting the channel level.  
6. Press the Tune or buttons if you want to select a certain channel for level readjustment  
or if you prefer to manually control the noise sequencing.

1. When Zone is selected, you have about five seconds to press a button to control the  
Zone. If the Zone is currently off, ZONE OFF appears in the displays. Use the On-Off  
button to activate the zone.  
2. Press the Zone button first to control the remote zone from the main zone. ZONE appears  
in the front panel and on-screen displays while you are controlling the remote zone.  
3. When ZONE is selected, the On-Off switch, the Volume ̅ and ̃ buttons and the Selector  
buttons operate in the same way as in the main zone except they are temporarily controlling  
the outputs at the Zone Audio and Video output jacks.  
4. Five seconds after making your adjustments to the remote zone, the AVC-2500 reverts  
to main zone operation. If you press the Zone button a second time within five seconds,  
controls revert to main zone operation.  
From the Remote Control  
1. When Zone is selected, you have about five seconds to press a button to control the  
Zone.  
2. Press the Zone button to control the remote zone from the remote control.  
3. When ZONE is selected, the On-Off switch, the Volume ̅ and ̃ buttons and the Selector  
buttons operate in the same way as in the main zone except they are temporarily controlling  
the outputs only at the Zone Audio and Video output jacks.  
4. Five seconds after making your adjustments to the remote zone, the AVC-2500 reverts  
to main zone operation. If you press the Zone button a second time within five seconds,  
controls revert to main zone operation.  
5. When controlling the remote Zone via an infrared repeater connected to the Zone 2 IR  
input there is no need to press the Zone button first.  
6. Press the Zone button first to control the main zone from the remote zone infrared control  
input.  
“P” Power indicator  
There is a P symbol in front panel display to let you know when either or both zones are  
powered on. When both zones are turned off, the entire P symbol appears in the display.  
When you turn on the main zone, the normal status indicators appear in the front panel  
display.  
If the main zone is turned off while the remote zone is active, the leg "|" of the P remains  
lit as long as the AVC-2500 is in this operational state. If the remote zone is turned off while  
the main zone is active, the loop "  
" of the P remains lit for five seconds before the front  
panel display returns to normal. If you press the Zone button when the remote zone is turned  
off, ZONE OFF appears in the displays.  
Temporary Level Adjustment Using the Trim Function  
The Trim button on the remote control temporarily reassigns the Volume ̅ or ̃ buttons to  
adjust channel levels as you listen. You have about five seconds to make a level adjustment  
before the Volume ̅ or ̃ buttons return to normal operation. The order of the AVC-2500’s  
channel Trim function matches established listener priorities for making adjustments quickly:  
Subwoofer, Surround (LS and RS together), Center, and LFE. The Trim function is for  
making adjustments “on-the-fly”, so its on-screen display is superimposed on the picture  
you are viewing instead of turning the entire screen blue or red as during Calibration. Trim  
settings are temporary; pre-calibrated levels are reset when the AVC-2500 is turned off.  
You will probably adjust the Subwoofer channel most frequently, because bass levels vary  
widely between movies and music sources.You will most likely choose to adjust the Surround  
channels next to affect spaciousness and depth. Since there is no reason to trim the LS and  
RS channels separately, their adjustment is combined for your convenience. The Center  
channel is the next priority trim adjustment for dialog. Last, you can trim the low frequency  
effects (LFE) level if any LFE material is encoded in a 5.1 DVD.

To Trim Individual Channel Levels  
1. Press the Setup/Trim button on the remote control until source SPEAKER LEVEL TRIM,  
SUBWOOFER [PRESET CAL LEVEL] dB appears on the front panel or on-screen display.  
2. Press the Volume ̅ or ̃ buttons to adjust the subwoofer to the desired level.  
3. Press the Tune or buttons to select the next or previous channel for adjustment.  
4. Repeat steps 2 and 3 to set levels for surround, center, and LFE channels.  
5. Press the Setup/Trim button at any time during the Trim process to exit Trim and restore  
the Volume ̅ or ̃ buttons to their normal function.  
Activating the Sleep Timer  
The Sleep button sets the AVC-2500 to automatically turn itself off. Each press of the Sleep  
button adds 15 minutes to the sleep timer, up to a maximum of 90 minutes. During the last  
two minutes of the sleep timer, the volume level gradually drops before theAVC-2500 turns  
off.  
To Activate the Sleep Timer  
1. Press the Sleep button on the remote control until source SLEEP TIMER ON appears in the  
on-screen display. A clock symbol appears in the front panel display.  
2. Each press of the Sleep button adds 15 minutes to the sleep timer. When the sleep timer  
is active, the front panel display automatically dims.  
3. Press and hold the Sleep button to cancel the sleep timer.  
MaintainingYour AVC-2500  
Your AVC-2500 requires no periodic maintenance and has no user serviceable parts inside.  
To avoid the risk of electric shock, do not remove the top cover. Clean the chassis with a soft  
cloth moistened with glass cleaner or water. Never use solvents or abrasives  
In Case of Trouble  
Call your Parasound dealer or Parasound Technical Service Department. We can suggest  
other diagnostic tests you can easily perform. If we determine that your amplifier should be  
returned to Parasound or an Authorized Parasound Warranty Center for inspection and pos-  
sible servicing, call Parasound for the location of a warranty center near you or shipping  
instructions for return to Parasound.  
Returning your AVC-2500 to Parasound for Service  
If we determine that you should send your AVC-2500 to Parasound, you will need to obtain  
a Return Authorization (RA) number. The RA number must be clearly marked on the outer  
carton only. Ship the unit with adequate insurance and a copy of your purchase receipt  
inside to validate your warranty. Warranty repairs will only be performed by Parasound or  
authorized warranty centers on sets where your purchase receipt is from an Authorized  
Parasound Dealer or Parasound Reseller. Units purchased from unauthorized dealers are  
not eligible for warranty repair.  
Units that arrive without an RA number, without a suitable shipping carton or with evidence  
of improper internal packing materials may be refused. We do not accept collect shipments.  
After repair under warranty, the unit will be returned to you via prepaid UPS within the  
Continental United States. In the case of a non-warranty repair, contact us and we will  
advise you of the repair charges before you ship the unit to us. The same packing and Return  
Authorization number requirements apply.  
54  
 
Important Notice Before Shipping your AVC-2500  
Before you ship the unit to Parasound, you MUST repack the unit into its fitted foam insert  
sandwich and its original carton. Use of any other carton and packing materials will prob-  
ably result in shipping damage. Common carriers such as UPS will not pay claims for dam-  
age incurred during shipment when products are surrounded only with styrofoam “peanuts”  
or placed in non-original factory cartons. Repairs for shipping damages because of mis-  
packing are your sole responsibility. If you do not have the original packing cartons and  
foam inserts, call us for new packing material that we can provide to you at a nominal  
charge.
