You Need The RU-VDA4!
The RU-VDA4 is part of the group of RACK-UP products from Radio Design Labs. RACK-UPs feature the
advanced circuitry for which RDL products are known, combined with accessible user-friendly controls and
displays. The ultra compact design permits high-density installations, with three products mounted in a
single rack unit! Single RACK-UPs can be mounted right where they are needed using the adhesive
method popularized by RDL’s STICK-ON
a RACK-UP module above, below, or in front of any flat surface!
APPLICATION: The RU-VDA4 is the ideal choice in most applications where video signals need to be
distributed. Video inputs and outputs are made on the front panel BNC jacks. Power connections are
made using full-size barrier block terminals on the rear panel.
The RU-VDA4 has two jacks in the bridging input stage. One jack is for the input signal; the other is a
loop-through output of the source signal. If 75-Ohm termination of the input signal is required, the
terminator (provided) is plugged onto the Loop Out jack.
Gain is user adjustable from the front panel. The gain potentiometer allows adjustment from –1 dB to +7 dB.
Four source-terminated outputs are provided through the BNC output jacks. Unused outputs need not be
terminated. A convenient (write-on) label area is provided to identify the feed from each output jack.
A unique feature of the RU-VDA4 is the 1V VIDEO INTO TERMINATED LOAD LED indicator. While not
intended as precision test equipment, this indicator can prove very helpful in field and remote location
setup. The indicator is off when the video signal drops below 1 Vp-p, and comes on when the signal just
achieves 1 volt.
Wherever a video distribution amplifier is needed to provide wide-band video feeds, gain adjustment,
reliability, compactness and unsurpassed versatility, the RU-VDA4 is the ideal choice. Use the RU-RA3
rack-mount adapter to mount multiple RU-VDA4s, or to combine related products (such as audio mixing,
audio distribution, or audio metering) into a single rack unit!

... OUTPUT: Connect the coaxial cable to the desired output(s) on the RU-VDA4, and label them as desired. GAIN ADJUSTMENT: Adjust the GAIN potentiometer for 1 Vp-p video level on your instrumentation. In the absense of test equipment, the 1V VIDEO INTO TERMINATED LOAD LED may be used. First turn the gain counter-clockwise. Then advance the GAIN clockwise until the 1V VIDEO INTO TERMINATED LOAD LED just illuminates ...
