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.Eachof the sixAudio/Videoinputs alsoswitchesanaccompanyingNTSC/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 fiveAudio/Video or six Audio-only inputs you select.
1. Connect the left and right audio output connectors from theVCR 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 theAVC-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 andVideo 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 theZone 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.

18
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 theAVC-
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 6input 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
atwochannelamplifierorto two channels ofamulti-channel amplifier thatarethen connected
to your main front left and right (L, R) speakers.

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 yourAVC-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 uninterruptedAC 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.

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.
AudioTrigger
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 ΩCoax 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.

Antenna Connections
You will not be able to receive any radio stations unless you connect FM andAM antennas
to the AVC-2500. The following are options to connect FM and AM antennas:
FM Dipole Antenna
A standard FM “folded dipole” 300 Ω 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 Ω
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
ΩΩ
ΩΩ
Ω Coaxial Antenna
TheAVC-2500 has a standard DIN-type 75 Ωconnector with a push-on coaxial FM antenna
plug. An adapter is included to accommodate the threaded F-type connectors that are used
in NorthAmerica.
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 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 T V 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 theAVC-2500. Contact your
Parasound Dealer or Custom Installer for more information regarding interfacing an external
control system to your AVC-2500.
ComponentVideo Connections
EachComponentVideo 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 videoY, 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.
