In addition to mounting the MPA 181T unit to a rack or under
furniture, it can also be projector mounted using the optional
kits PMK 350 (part #70-563-02, -03) or PMK 300 (part #70-374-
01). See figures 2-4 and 2-5 on the following page.
To projector mount the MPA 181T, do the following:
1 . If necessary, remove the feet from the bottom of the device
to be installed.
2 . Mount the MPA 181T to one of the bracket’s three
mounting plates. The device can be horizontally mounted
facing either up or down, whichever is most convenient.
See the illustrations on the following page.
Use two supplied 4-40 x 3/16 screws in opposite
(diagonal) corners to secure the device to the bracket.

Under-desk mounting
In addition to using the MPA 181T unit on a rack or projector, it
can also be mounted under furniture (or under a desk). Mount
the unit by using the optional mounting kit (part #70-077-01) for
furniture, as follows:
1 . Attach the mounting brackets to the amplifier with the
machine screws provided (figure 2-3).
2 . Hold the amplifier with the attached brackets against the
underside of the table or other furniture. Mark the
location of the screw holes of the bracket on the mounting
surface.
3 . Drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.3 mm)
deep in the mounting surface at the marked screw
locations.
4 . Insert #8 wood screws into the four pilot holes. Tighten
each screw into the mounting surface until just less than
1/4" of the screw head protrudes.
5 . Align the mounting screws with the slots in the brackets
and place the interface against the surface, with the
screws through the bracket slots.
6 . Slide the unit slightly forward or back, then tighten all
four screws to secure it in place.
