Connect your Output Displays
Now that the Video and Audio Inputs are connected to your KD-CDA3, run each of
the individual set of Output connectors to their respective “Display” devices. The
three (3) Output port banks are labeled Output 1, Output 2, and Output 3.
Always test all connections and final operation first, before sealing cables
behind walls or completing difficult wire routings.
Caution: For proper operation of the high-quality electrical
circuits in your KD-CDA3 unit, you MUST ensure for each Output:
Each run of YPbPr cable MUST be the same length
Maximum run length = 300 feet

Input
S-Video
For SDTV S-Video, simply follow the labels on your KD-CDA3 and connect the Y and
color (chrominance) signals. Use the “Y” Input of the KD-CDA3 for the S-Video Y sig-
nal. Note that if you may use either the Pr or Pb Input for the S-Video chrominance
signal. However, be sure to correspondingly use the same (Pr or Pb) when driving
your displays. For example, if you input the S-Video color signal on the Pr path, then
you MUST use the Pr Outputs of the KD-CDA3 to drive your S-Video displays. You
may require breakout cables or adapters to the RCA Inputs of the KD-CDA3.
Composite Video
SDTV Composite Video, frequently called CV or CVBS, is a single-wire video format.
You must use one of the three KD-CDA3 inputs for the Composite Video Input, and
correspondingly use the same Output label to drive your Composite Video display.
For example, use the “Y” Inputs and Outputs. This way, you will have three (3)
Composite Video Outputs. You can achieve a higher level of CVBS distribution, for
driving up to seven (7) Composite Video displays, by feeding back the KD-CDA3
Outputs to the open KD-CDA3 Inputs. Refer to the Application Example for
Composite Video provided later in this Operating Manual. You may require breakout
cables or adapters to the RCA Inputs of the KD-CDA3.
