KD-CDA3 Operating Instructions

Be careful not to confuse the Red lead of a Component Video (YPbPr) cable with the Right or Red audio channel. To avoid confusion, note that the Red lead (Pr) from the Component Video cable is often bundled to the Green lead (Y) and Blue lead (Pb) from the component cable. Typically an analog Audio cable is comprised of a Right- channel stereo (Red-colored) connector together with a Left-channel stereo (White- colored) connector.

KD-CDA3 Operating Instructions

Connect your COMPONENT VIDEO Source Input

Before supplying power to your KD-CDA3 HDTV Distribution Amplifier unit, connect the Output of the Component Video Source device you wish to distribute to your dis- plays to the Inputs of KD-CDA3.

Typically, connecting the KD-CDA3 HDTV Distribution Amplifier into your system is as simple as matching the proper color-coded connectors. When inserting the RCA con- nectors use a slight twisting motion when inserting the cables, this assures a proper connection by seating the RCA connector all the way in. Be sure to use high-quality 75 Ohms cables for the video. When running long lengths of cable please make sure to use heavy shielded high quality cables.

Caution: For proper operation of the high quality electrical

circuits in your KD-CDA3 unit, do NOT “daisy chain” Inputs:

■Each Input of the KD-CDA3 has its own 75 Ohms termination

■Do NOT feed a Source to multiple KD-CDA3 Inputs without proper Distribution equipment

Note: Since the KD-CDA3 HDTV Distribution Amplifier does NOT perform video processing, the output video format is the same as the input video format. This means that the video resolution is not changed and also that if you input one form of video, for example Component Video, the output will be in exactly the same format.

“VGA” Video Inputs

The “Source” device Outputs should be connected to the jacks marked “Input” on the KD-CDA3. After hooking up the “Source” device to the marked input connectors, the KD-CDA3 will distribute the selected input signal to all of the output connectors.

Alternate Video Inputs

RGBHV

RGBHV installations with separate H & V syncs preclude Audio distribution with your KD-CDA3 unit. Simply follow the labels on your KD-CDA3 and connect the RGB Video signals, and H&V Sync signals, accordingly. You may require breakout cables or adapters to the RCA Inputs of the KD-CDA3.
