Introduction
Included in this package:
• One KD-ADA4 HD View4
• One external power supply
• One 75 Ohm terminator
• One Operating Manual with included Warranty statement
The KD-ADA4 HD View4 is a very versatile and novel Distribution Amplifier
(DA) that will suit your needs for crystal-clear distribution of HDTV and SDTV
Component Video (YPrPb) or Composite Video (CV) sources to Component
Video "HDTV-ready" monitors, or Composite Video monitors. Signal process-
ing circuitry permits excessive distribution cable runs of up to 1000 feet, sim-
ply by adjusting the front-panel knobs. And you can drive four component or
composite monitors simultaneously. Each unit handles Left and Right stereo
audio, or digital PCM audio.
HD View4 provides so much flexibility, yet will not degrade the image quality
of your input signals. Each unit can be cascaded to other KD-ADA4, KD-DA6,
or KD-CDA12 DA’s by Key Digital Systems, to drive as many outputs as
desired from one source. HD View4 has an added feature (via internal DIP-
switch control) whereby you can distribute only Composite Video (CV) or digi-
tal PCM audio inputs to as many as 24 destinations.

Product Overview
Why do you need a Distribution Amplifier?
For installations where you need to distribute your HD and SD video and analog or dig-
ital audio to more than one destination, you need a high-quality Distribution Amplifier
(DA). Perhaps you have a configuration where you need to distribute an HDTV Set
Top Box output to several different display monitors. You’ll want to feel confident that
the DA introduces little or no degradation to your signals.
Our DA’s produce crystal-clear images which do not harm your input signals, can drive
long cables (typically up to 300 feet, and our ADA4 which can drive up to 1000 feet),
and can be cascaded to accommodate future expansion requirements. Let us help you
choose exactly the right DA for your specific installation application.
The KD-ADA4 HD View4 Distribution Amplifier offers versatility, convenience, and well
thought-out features:

Quick Set Up
Connecting and using your KD-ADA4 HD View4 is a simple process.
KD-ADA4
STEP A: Configure your KD-ADA4 HD View4 Distribution Amplifier.
NOTE: Do not attempt to connect power to the unit during any of
the configuration steps.
STEP A1: Determine your configuration requirements. The KD-ADA4 HD
View4 has an "ADA4 Mode" and a "PCMD4 Mode" as described below.
Typical "ADA4 Mode" applications:
• Distribution of your YPrPb and Left & Right analog or digital PCM audio inputs
to as many as four separate Component Video monitors. In this case, the I/O
Connectors Groups would be used as shown:
KD-ADA4
Pr Y
LRPCM

STEP A2: Set the internal DIP switches to match the Configuration Mode
you need for your application.
• Remove the front panel using a screwdriver, and find the six 8-bit DIP
Switches. Be sure to configure the six 8-bit DIP Switches as shown in the table
below for either the ADA4 or PCMD4 Mode:
STEP B: 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 con-
nect 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
distributed, 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 dis-
tributing 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

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.
