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)

NOTES:

• The input receptacle may be labeled in one of two ways: the ground pins of the input

connector port may be labeled or (see the images to the right). The wiring and

function are the same whichever way the product is labeled

• The MPA 401 amplifier sums the left and right signals from both the TRS and RCA

inputs to form Sum 1. Sum 1 is then weighted. At the same time, the amplifier sums

the left and right signals from the captive screw input to form Sum 2. Sum 1 and Sum 2

are then summed together to form a single mono signal. See figure 6 on page 9 of the

MPA401 Series User Guide for more details.

• The captive screw, RCA and TRS inputs are buffered.

Ensure that the audio output of the projector is set to variable out. Multiple input options can be

used simultaneously and result in summing.

Step 5 — Connect power cords to the MPA 401 and other audio

equipment. The MPA401 ships with an Extron 36W desktop power

supply.

Connect the pre-wired captive screw connector into one of the two pole,

3.5 mm captive screw outlets on the power supply and the other end into

the power receptacle on the amplier (see the gure to the right). The

power cord connectors are correctly wired when shipped.

ATTENTION:

• See the attention notices in the Power Input section of the

MPA401 Series User Guide for important information about using

power supplies.

• When the 36 W power supply is connected to the MPA 401, it

must not be shared with any other devices.

Step 6 — Adjust the MPA 401 input level, bass, and treble from the front panel (see gure at right).

1. If necessary, unplug the remote connector from the unit (see step 7, below).

2. If connecting the amplier to a system with adjustable volume, set the volume to its lowest

point. Then adjust the MPA401 front panel level potentiometer fully counterclockwise.

3. Set the system volume to its maximum volume level (no sound should come out).

4. Return to the MPA 401 and raise the level until sound distortion rst occurs, then lower slightly until the distortion disappears.

This setting ensures that, whatever the system volume setting may be, no clipping occurs.

5. Adjust bass and treble to preference.

Step 7 — The rear panel 3-pole Remote captive screw receptacle on the amplier can be

used for remote control of the volume by an Extron volume controller such as an Extron

VCM100 AAP, VC 50, or MLA VC10 Plus. A MediaLink controller can also adjust the audio

volume via a network connection or by IR remote (see the MPA 401 Series User Guide).

NOTE: Control signal ground pins may be labeled as or “G.” The wiring and function

are the same, whichever way the product is labeled.
