About this Manual
About the MDA EQ Series Mini Distribution
Amplifiers
This manual provides information on the Extron VersaTools®
MDA EQ series video distribution amplifiers and discusses how
to install and operate them.
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.
Connection diagrams

mounted on the inside of the bracket.
3. Using the two included tie wraps, strap the power supply
to one of the brackets.
4. Place the contoured bracket base against the projector
ceiling pole and opposite the back plate. The pole should
fit snugly into the depression in the center of the
contoured base.
N The PMK 300 has a hole in the bottom plate that allows
the projector pole to be inserted through the center of the
plate, rather than outside of the plate (see the illustration
on the next page). To install the PMK 300 in this
configuration, slide the bracket up from the bottom of the
pole before the projector is installed on the pole.

5. Place the U-bolt around the ceiling pole and insert the two
legs of the U-bolt through the round holes in the
contoured base, then through the slotted holes in the
bracket’s mounting plate.
• For a typical (1.5" to 2.0" diameter) pole — You can
use the supplied U-bolt, which fits a typical ceiling
pole.
• For a smaller or larger pole — Locally obtain a
U-bolt that fits your ceiling pole. The slotted holes
on the bracket can accommodate a U-bolt for pole
sizes from 1.0" to 2.5" in diameter.
6. Secure the bracket to the U-bolt with the included hex
nuts.
PMK 350 Projector Mounting Kit
The PMK 350 Low Profile Projector Mounting Kit is an aboveprojector mounting kit that attaches to a 1.5" to 2" diameter
projector mounting pole. It can hold more than one device, in a
variety of sizes.
The PMK 350 is available in black (part #70-563-02) or white
(part #70-563-03).
Follow these steps to mount the MDA EQ on the PMK 350:
1. Remove the front panel from the PMK, using a #2 Philips
screwdriver. Retain the four screws to reattach the plate
when finished.
2. Remove any rubber feet from the bottom of the MDA EQ.
3. Secure the MDA to one side of the mounting bracket, using
two of the supplied 4-40 x 3/16" screws in opposite
(diagonal) corners. Use an Extron Tweeker (provided) or a
Philips #1 screwdriver to tighten the screws.
4. Using the two included tie wraps, strap the MDA EQ
power supply to the PMK bracket.
5. If desired, remove the back panel of the PMK 350 and
mount an additional MDA or other device(s) at the back of
the bracket, as described in step 3.
