Step 1

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

 

Step 2

— Mount the amplifier in either a

plenum

space, on

a rack, under a desk, or on a projector.

 

 

 

 

ATTENTION: Although the amplifier 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 amplifier 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 amplifier and does not provide secure mounting for the unit.

Step 3 — Attach the speakers to the MPA 401 using the 2-pole, 5 mm screwlock captive screw speaker receptacle on the rear panel. (The old and new silk screens for the MPA 401100V are shown to the right).

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

amplifier.

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:

zz One pair of RCA receptacles (unbalanced)

zz One 3.5 mm stereo tip-ring-sleeve receptacle (unbalanced)

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