This manual provides information on the Extron VersaTools®  
MDA EQ series video distribution amplifiers and discusses how  
to install and operate them.  
The following diagrams give examples of how the various  
supported devices can be connected to an MDA EQ series  
product. (These diagrams show connections for the

About the MDA EQ Series Mini Distribution  
Amplifiers  
LCD  
Projector  
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.

PMK 100 Mini Projector Mounting Kit  
The PMK 100 is a projector mounting kit (part #70-217-01)  
designed for use with Extron 1U high, quarter-rack width  
products like the VersaTools products. It allows them to be  
mounted near or on a projector support.

3.  
Attach the projector mounting bracket to the side of the  
MDA EQ, using the provided machine screws.  
On the side mounting plates, the MDA is typically  
mounted on the outside of the bracket.  
On the front mounting plate, the device is typically  
mounted on the inside of the bracket.  
Secure the unit to a projector mount or other surface by  
inserting the mounting bolt through the bracket’s slotted  
hole.  
3.  
4.  
Using the two included tie wraps, strap the power supply  
to one of the brackets.  
See the illustration on the previous page.  
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.  
PMK 300 Projector Mounting Kit  
The PMK 300 Multi-Product Projector Mounting Kit  
(#70-374-01) mounts up to three quarter-rack width products to  
a projector ceiling mount pole. The MDA EQ can be mounted  
above the display device with the front panel facing either  
down or up. The quarter rack width plate can also be used to  
mount the MDA external desktop power supply.  
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.

Follow these steps to mount the MDA EQ on the PMK 350:  
7.  
Assemble the U-bolt and the following parts in the order  
they are listed below:  
1.  
Remove the front panel from the PMK, using a #2 Philips  
screwdriver. Retain the four screws to reattach the plate  
when finished.  
a.  
Pass the legs of the U-bolt through the slotted holes  
on the back of the mount plate flange.  
b.  
c.  
Place the U-bolt legs around the ceiling pole.  
2.  
3.  
Remove any rubber feet from the bottom of the MDA EQ.  
Pass the U-bolt legs through the round holes in the  
contoured base.  
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.  
Place the contoured base against the pole and  
opposite the mount plate flange. The pole  
should fit snugly into the depression in the  
center of the contoured base.  
4.  
5.  
Using the two included tie wraps, strap the MDA EQ  
power supply to the PMK bracket.  
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.  
d.  
Pass the U-bolt legs through the round holes in the  
L bracket.  
8.  
Align the two round holes in the bottom of the L bracket  
with the two slotted holes in the base of the PMK 350, on  
either side of the opening for the pole; and attach the L  
bracket to the base by inserting the two provided 6-32 x  
5/16" screws through the aligned slots. Tighten the screws  
slightly; you should still be able to slide the L bracket to  
adjust it as needed.  
6.  
Place the PMK 350 mounting tray around the projector  
ceiling mounting pole. (See the illustration on the next

however, the plug for the power cord may be either  
orange or blue. Either color plug can be connected to the  
rear panel receptacle.  
The following figures show the back panel configurations of the  
three MDA EQ models.

To wire the connector:  
1. Cut the DC output cord to the length needed.

2. Strip the jacket to expose 0.2" (5 mm) of the conductors for  
the blue captive screw plug, or 0.3" (7 mm) for the orange  
plug.

Exposing more than the amount of copper wire  
described above could allow the stripped wires to  
touch each other, causing a short circuit. This  
could result in the external DC power supply  
overheating and/or burning.

Stripping the wires to expose less than the recommended  
amount causes them to slide out of the connector too  
easily, even if they are tightly pinched by the captive  
screws.

5. To verify the power cord’s polarity before connecting it,  
plug in the power supply with no load and check the  
output with a voltmeter.

Your MDA may have shipped with a blue captive screw  
plug. The blue connector does not have the extended tail

Do not tin the stripped power supply leads before  
installing the captive screw connector. Tinned  
wires are not as secure in the captive screw  
connectors and can be easily pulled out. They may  
also break after being bent several times.
