Introduction

Congratulations on your purchase of this precision component and thank you for selecting
Parasound. Your new AVC-2500 Audio V ideo 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 your AVC-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 dual­stereo “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 extensiv e 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

notice any , contact your Parasound Dealer immediately. Be sure to sa ve 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. Y ou should also k eep the unit away from heat sources such as hot air
ducts, radiators and moisture sources such as open windows.

Optional Rack Mounting Kit

Making Connections to Y our 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 the AVC-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 six Audio/Video inputs also switches an accompan ying NTSC/P AL 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 the AVC-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 V ideo 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 discr ete 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 the AVC-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 amplif ier that are then connected
to your main front left and right (L, R) speakers.

Center Channel Output

Connect the Center channel output of your AVC-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 Surr ound output jacks of your AVC-2500 to the inputs of the two
channel amplifier or to two channels of a multi-channel amplif ier that are connected to your
left and right surround (LS, RS) speakers.

Subwoofer Output Connections

T wo Subwoofer output jacks are pro vided for your conv enience if you have two subwoofer s.
For passiv e 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. W e recommend that you switch
off the crossover on your subw oofer amp and use the 24 dB per octav e lo w 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 standard A C receptacle accepts the A C 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.

best reception.

ΩΩ

75

Ω

Coaxial Antenna

ΩΩ

The AVC-2500 has a standard DIN-type 75 Ω 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 receiv e and the superior sound quality
will make the extra effort worthwhile. Connect the outdoor antenna with a 75 Ω coaxial
cable directly to the 75 Ω FM Antenna Input of the AVC-2500. If you use 300 Ω twin lead,
connect the two bare wire leads to the included “balun” adapter and press it onto the female

75 Ω 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 Contr ol 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 re garding interfacing an external
control system to your AVC-2500.

Component Video Connections

Each Component V ideo Input and the Component V ideo Output includes three separate jacks.
Separating the video signal components of luminance (Y) and the color difference (Cb and
Cr) delivers the v ery 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. Y ou can select whether the on-screen display will appear at the Component V ideo
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
V ideo Input connectors of the AVC-2500. Once you have connected the component video

sources to the inputs of the AVC-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 hav e
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 the AVC-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-Optic T oslink Input Connections

Each of the two fiber-optic T oslink inputs on the AVC-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 T oslink 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

Ω Ω

Ω

Balanced Input Connection

Ω Ω

The AES/EBU (Audio Engineering Society/European Broadcast Union) 110 Ω 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 A C-3 RF output jack of your laser disc player . Use a 75 Ω cable with an RCA
plug on each end to connect your RFD-1 to your laser disc player.

21

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 e xclude
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 six Audio/Video inputs has both composite and S-video connectors with se parate
video circuits and amplifiers. The AVC-2500 can only convert video signals from S-video to
composite video, but not vice versa. F or example, when you connect a video signal to one of
the six composite RCA input jacks, the video signal will only be available thr ough 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

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 the AVC-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 the AVC-2500 has automatically detected an
analog, PCM, or 2/0 Dolby Digital signal. Howev er , Pro Logic processing is only a v ailable
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. The AVC-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 f lashes,
the AVC-2500 will attenuate the signal just until the internal analog-to-digital converters
are no longer overdriv en and the overload indicator stops flashing. This new le vel 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.

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 adv anced feature takes the guesswork out of selecting the
correct surround mode every time you play a dif ferent source. Source components transmit
their signals in two channel Analog, Pulse Code Modulation (PCM), Dolby Digital, or DTS.

Cinema Mode

Dolby Digital

Dolby Digital deliv ers 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, r ealistic ambience. The sixth channel, the Low Frequency Ef fects Channel
(LFE), contains additional bass information to maximize the impact of scenes with special
effects such as explosions, crashes, etc. The LFE channel frequenc y 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 Cinema ASP mode, the AVC-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 3/2 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 D VD 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.

Tw o-channel PCM

PCM encoded material is found on compact discs and laser discs digital outputs. In the
Cinema Autoformat Surround mode, the AVC-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 Cinema Autoformat 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 benef it
from activating THX Ultra technologies. THX should be selected when watching movies
that were mixed primarily for playback in large mo vie theater environments in which speakers
are always mounted behind the screen. THX engineers dev eloped patented technologies to
accurately translate the sound from the movie theater environment into the home, correcting
for significant tonal and spatial discrepancies between these en vironments. When the THX
mode is selected on the AVC-2500, the decoded signal is modified with the follo wing 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 f ilm 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.

THX Timbre 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 pro vide 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 f ilters 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 speak ers. 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 Music ASP mode, the AVC-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 Music ASP mode , the AVC-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

Tw o-channel PCM

PCM encoded material is found on compact discs and laserdiscs. In the Music ASP mode,
the AVC-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 two­channel audio in the left, center, and right channels. Proprietary ambiance ef fects 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, the AVC-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 Party ASP mode, the AVC-2500 automatically decodes DTS encoded source material.
DTS is always encoded in 5.1, but the AVC-2500 plays back downmixed tw o-channel in the
front left, right and rear surround channels in a “dual-stereo” configuration. The subwoofer
is active in this mode.

Tw o-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 two­channel audio in the front left, right and rear surround channels in a “dual-stereo”
configuration. The subwoofer is acti ve 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 Stereo ASP mode, the AVC-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 Stereo ASP mode, the AVC-2500 automatically decodes DTS encoded source material.

Placement of Your Home Theater Speakers

Speaker Placement

Proper speaker placement is essential for optimum performance of your home theater sys­tem. The following are basic guidelines for speaker placement based upon idealized condi­tions. You may need to make placement compromises to allow for room shape, furniture
placement, windows, doorways, and other considerations. The AVC-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 r eproduce 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 prev ent 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 r ight
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 loca­tion, 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 (b ut certainly understandable) desire for intense bass. Ho we v er note
that positioning two subs for ideal response is more challenging than positioning one, be­cause 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.
Howev er , there are eight le vels 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

T o make the setup process easier , we have segreg ated 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 f actory 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/Tr im. Once you have opened the complete
menu, all levels of setup are accessible until you press Shift then Setup/T rim again or restor e
the system defaults.

For easy identification, advanced setup options are gray highlighted in the
following setup pr ocedures.

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 fi v e ASP modes to be matched to an y of the twelv e
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

g g

Digital button and Rotary Knob or the Digital

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

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 and ASP 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.

The next steps in the setup process are to:

1. Rename the AVC-2500’s twelv e 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 v olume level of that Source to match the lev els of the other sources (if desired).

5. Set the input level to the analog to digital converters (if necessary).

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

on the front panel and on-screen displays.

Setting the Bass Limiter:

With the e xtra low frequency content mix ed 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, lea ve the Bass Limiter at its default 0 dB setting and use
sensible master volume lev els.

Setup Menu Level Three - Calibrating Channel Levels

The AVC-2500 is equipped with advanced circuitr y 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 al wa ys insure that its battery
is fresh. If you accidentall y drop the microphone or use it with a weak battery , you ma y 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.

3. Press and hold the Setup/Trim button on the remote control until SOURCE SETUP appears
on the front panel or on-screen display. Press Setup/Trim button until SPEAKER LEVEL

appears in the displays.

the displays.

8. Press Setup/Trim to advance to SPEAKER DELA Y SETUP, or press and hold the Setup/T rim
button for three seconds to exit SPEAKER LEVEL SETUP and return to normal operation.

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 relati ve signal strength from
your listening position. The AVC-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.

g g

before the Volume
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 pr obably 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) le vel if any LFE material is encoded in a 5.1 DVD.

Maintaining Y our AVC-2500

Your AVC-2500 requires no periodic maintenance and has no user serviceable parts inside.
T o av oid the risk of electric shock, do not remove the top cov er . Clean the chassis with a soft
cloth moistened with glass cleaner or water. Never use solvents or abrasive s

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 pos­sible 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.

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 prob­ably result in shipping damage. Common carriers such as UPS will not pay claims for dam­age incurred during shipment when products are surrounded only with styrofoam “peanuts”
or placed in non-original factory cartons. Repairs for shipping damages because of mis­packing 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.
