KD-CDA3 Operating Instructions

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 pre- clude Audio distribution with your KD-CDA3 unit. Once configured, there are no con- trols to operate and the unit will be “transparent” to your entire installation or applica- tion. It’s truly “configure and forget about it” - you are done.

KD-CDA3 Operating Instructions

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 diffi- cult 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.
