HD View4

KD-ADA4

STEP D: Adjust the front-panel potentiometers to compensate for the long cable Output runs of Y, Pr, Pb, and CV (Composite Video).

•The front panel of the KD-ADA4 HD View4 unit has four groupings, labeled Output 1 through Output 4, which match the physical distribution Output Groups 1-4.

•You will need an Ohmmeter set in the range of 75 Ohms. You will need to per- form the following procedure for each signal (CV, Pb, Y, Pr) for each Output Group (1-4).

•For the PCMD4 Mode distribution of PCM digital audio, be sure to set all KD- ADA4 Resistance values to 75 Ohms in the following procedures.

NOTE: POWER MUST BE TURNED OFF FOR THE KD-ADA4 AND ALL OTHER UNITS CONNECTED TO THE I/O CABLES WHEN PERFORMING THESE STEPS AND DIP SWITCHES SET TO ADA4 MODE.

STEP D1: Determine the resistance of each cable at the KD-ADA4 HD View4 end, when the cable is terminated at its destination. Use your Ohmmeter to measure the resistance of the cable, by removing the cable from the back of the KD-ADA4 HD View4 unit. This measurement is from the center point of the RCA jack to the outside of the RCA jack. Make note of this resistance value, called "Rload".

STEP D2: Determine the resistance of the KD-ADA4 HD View4. It is a simple calculation, KD-ADA4 Resistance = 150 Ohms - Rload.

STEP D3: Set the KD-ADA4 HD View4 resistance. First, insert the Ohmmeter cables into the top and bottom test sockets on the front of the KD-ADA4 HD View4 for the signal corresponding to the cable you measured. Using a small, slotted screwdriver or other implement, set the corresponding potentiometer (to the lower left of each signal’s Ohmmeter test socket) to the value calculated above for KD-ADA4 Resistance by comparing the Ohmmeter value to the desired value for KD-ADA4 Resistance.

STEP D4: Repeat the above procedure in its entirety for each output cable.
