SOURCE-COMPONENT POWER AND HOME THEATER
SYNCHRONIZATION SIGNALS
1. Video Synchronization from a Source Component
to a ZR-4630 Sync Input
An RCA Y-adapter is used to split the video output of a
source component for connection to one of the three
Sour
ce Sync Inputs of the ZR-4630 (2, 3, or 4). One side
of the RCA Y-adapter connects to the appropriate Source
Sync Input and the other side connects to the intended
destination for the video signal (i.e., the video input of a
TV, receiver or RF modulator).
The need for an RCA Y-adapter can be avoided if your
video source has two video outputs. One video output
connects to a Source Sync Input and the other to the
intended destination of the video signal.
Important Note: Source Sync Inputs are designed with
high-input impedances so as not to affect the quality of
the video signal w
hen using an RCA Y-adapter.
2. Voltage Sync from a Source Component to a
ZR-4630 Sync Input
When obtaining a 12V sync signal from a source compo-
nent (refer to the Source Po
wer Synchronization section of
this manual for more information), a Niles Accessory Cable
(FG00724) connected to a Radio Shack 274-326 mini-plug
to male RCA adapter provides proper connection to any of
the three Source Sync Inputs.
