SDP-3 Digital Surround Processor/Controller
Installation
Video Connections
The SDP-3 has eight composite and S-Video inputs. Connection to an
S-Video input will override the composite signal connected via the RCA-
type connector. Note that an S-Video input will be output on both the
composite and S-Video outputs. Composite input signals will not be
output as S-Video.
You can assign any video source to any (or all) of the eight SDP-3 inputs
via the Input Configuration submenu of the Setup menu. This can be
very useful in systems which use a VCR as the tuner for TV viewing, as
the video feed from the VCR can be assigned to both the VCR and TV
inputs. The VCR's audio signals can be fed to both inputs with Y-
connectors. (Do not use Y-connectors on video signals.) This allows the
audio and video signals from the VCR to be used for both TV and VCR
viewing.
You can also assign any video source to audio-only sources such as an
AM/FM tuner, to enjoy music from another source while viewing a video
source.
It is important to remember that the impedance characteristics of
composite video and digital audio are different from analog audio. You
should only use cables specifically designed for video and digital audio.
Digital Audio Connections
The SDP-3 has eight S/PDIF digital audio inputs: five coax via RCA and
three optical via TOSLINK™. The digital inputs can be set up to be
selected with any (or all) of the eight inputs via the Input Configuration
menu. Using the digital inputs will always provide superior performance.
Expansion Port Input Connections
The SDP-3 also has three digital audio expansion ports (A, B and C).
These coaxial digital audio inputs are capable of accepting stereo PCM
signals up to 24-bit/96kHz. Expansion Port A feeds the Left and Right
Front channels directly. Expansion Port B feeds the Center and
Subwoofer channels directly, and Expansion Port C feeds the Left and
Right Surround channels directly.
Note: These inputs are designed to completely bypass all of the digital
signal processing of the unit, including the crossovers and effects.
For DVD players that support true 24/96 digital audio outputs, we
recommend connecting one DVD digital audio output to Expansion Port
A, and another DVD digital audio output to one of the SDP-3's eight
S/PDIF digital audio inputs.
