This KD-CDA3 HDTV Distribution Amplifier accepts virtually any Component Video
input signal (YPbPr) with a matching left and right stereo audio pair (L&R audio can
be substituted by a single digital PCM audio connection), and distributes it to up to
three (3) Display devices around your home or showroom without the loss of signal
quality. “VGA”-like video, called RGBHV, can be used in place of the Component
Video and Audio. A typical hookup will consist of a “Source” device that outputs
Component Video (or Composite Video or S-Video with optional video adapters) such
as a DVD player, Set-Top Box unit, Satellite receiver, digital VCR, Sony-PlaystationÍ,
XBOXÍ, GameCubeÍ or any other consumer video device.
CAUTION: Always test all connections and final operation
first, before sealing cables behind walls or completing difficult wire routings. Since the KD-CDA3 HDTV Distribution
Amplifier does NOT perform video processing, the output
video format and resolution is the same as the input video
format and resolution. This means that the video resolution
is not changed and also that if you input one form of video,
for example Component Video (YPbPr), the output will be in
exactly the same format.

Getting Started
The
KD-CDA3 HDTV Distribution Amplifier
is capable of distributing any Analog
three-wire Component Video (YPbPr) and/or five-wire “VGA”Video (RGBHV) source,
as well as analog/digital audio, to as many as three (3) outputs (typically your displays
or projectors). If your source device output is on a VGA connector, you will need a
breakout cable to RGBHV on separate RCA connectors; RGBHV installations preclude Audio distribution with your KD-CDA3 unit. Once configured, there are no controls to operate and the unit will be “transparent” to your entire installation or application. It’s truly “configure and forget about it” - you are done.
