Under-desk mounting

In addition to using the MPA 122 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 (Extron part #70-

212-01) for furniture, as follows:

1.	Attach the mounting brackets to the amplifier with the
	machine screws provided (figure 2-3).
2.	If feet were previously installed on the bottom of the
	interface, remove them.
3.	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.
4.	Drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.3 mm)
	deep in the mounting surface at the marked screw
	locations.
5.	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.
6.	Align the mounting screws with the slots in the brackets
	and place the interface against the surface, with the
	screws through the bracket slots.
7.	Slide the unit slightly forward or back, then tighten all
	four screws to secure it in place.

(part #70-374-01).

Only VersaTools products and most IP Link products

	can be mounted using the multi-product projector
	mounting kit.
To projector mount the MPA 122, do the following:
1.	If necessary, remove the feet from the bottom of the device
	to be installed.
2.	Mount the MPA 122 to one of the bracket’s three mounting
	plates. The device can be vertically mounted facing either
	up or down, whichever is most convenient. See the
	illustration below.
	Use two supplied 4-40 x 3/16 screws in opposite
	(diagonal) corners to secure the device to the bracket.
