Step 1 — Turn all of the equipment off and disconnect all power sources.

Step 2 — Mount the amplier in either a plenum space, on a rack, under a desk, or on a projector.

ATTENTION:Although the amplier is plenum rated, the power supply provided with it is not. The power supply must not be

placed in the plenum space. Cables to and from the amplier must be plenum rated.

NOTE:Use only the two round mounting holes for mounting the MPA 401. The other four (hexagonal) holes anchor stand-offs

for the internal circuit boards. Using them may damage the amplier and does not provide secure mounting for the unit.

Step 3 — Attach the speakers to the MPA 401 using the 2-pole, 5 mm screw-lock

captive screw speaker receptacle on the rear panel. (The old and new silk screens for the

MPA401-100V are shown to the right).

ATTENTION:Do not ground or short the speaker outputs as this will damage the

amplier.

NOTE:The mono audio speaker receptacle may be labeled in one of two ways (see

the images to the right). The wiring and function are the same whichever way the

product is labeled.

Step 4 — Attach sources to the MPA 401 unit from the audio source or projector.

The three rear panel audio inputs can be used individually or together:

zOne pair of RCA receptacles (unbalanced)

zOne 3.5 mm stereo tip-ring-sleeve receptacle (unbalanced)

zOne 3.5 mm, 5-pole captive screw receptacle (balanced or unbalanced)
