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.
