About this Manual
This manual provides information on the Extron VersaTools®
MDA EQ series video distribution amplifiers and discusses how
to install and operate them.
About the MDA EQ Series Mini Distribution
Amplifiers
The Extron MDA EQ series are compact composite video and
S-video mini distribution amplifiers with individual output gain
and equalization controls that compensate for different cable
lengths for each output. (Each adjustment on the MDA 4SV EQ
model equalizes two outputs.) The MDA EQ products are also
line drivers, able to handle 1000 feet of Extron Mini HR cable.
Models
MDA 2V EQ — One input, two outputs, composite video with
equalization and gain controls for each output
MDA 4V EQ — One input, four outputs, composite video with
equalization and gain controls for each output
MDA 4SV EQ — One input, four outputs, S-video with luma
(Y) equalization control, and luma and chroma gain controls for
every two outputs
Features
Individual equalization and gain controls — Gain and
equalization (EQ) adjustments allow optimized compensation
for outputs with various cable lengths for different applications.
Video loop-through — All models feature a 75 ohm video loop-
through connector, which provides for local monitoring and
cascading to another distribution amplifier.
Power supply — An external desktop 12 VDC power supply
with a two-pin captive screw connector accepts 100 to 240 VAC
input.
Enclosure — All models have the light, compact VersaTools 1U
quarter rack enclosure, three inches in depth.
Rack, projector, and furniture mountability — All models can
be mounted on a rack shelf, under a desk or podium, or on a
projector.
Global accessibility — Quad compatibility and universal
power supply enables the MDA EQ to be used worldwide.
