Connect your KD-ADA4 HD View4 Distribution Amplifier to your Input and Output sources.

NOTE: Do not attempt to connect power to the unit during the cable hook-up.

STEP B1: Based on your configuration selection, be sure to set the DIP Switches as described in STEPS A. Use color-coded RCA cables to connect the Inputs and Outputs to the back of the KD-ADA4 HD View4 unit. Output runs should not exceed 1000 feet. Each run of YPrPb cable MUST be of equal length per Output Group.

STEP B2: For the ADA4 Mode where less than four video outputs are distrib- uted, be sure to use the 75 Ohm terminator (supplied) to terminate either Y, Pr, or Pb of the first unused Output Group. For example, if distributing with only Output Groups 1 and 2, then place the terminator on Y, Pr, or Pb of Output Group 3. You should use the Output Groups in sequential order.

STEP C: Apply power to the unit:

Use ONLY the external wall-plug power supply provided with your unit, 110- 240V AC, 50-60 Hz, 0.9 Amps

Connect the 5-pin DIN external power supply connector to your unit, and plug the power supply into a power outle
