a
The power connector on the rear panel is orange; however,
the plug for the power cord may be either orange or
blue. Either color plug can be connected to the rear panel
receptacle.
N
To wire the connector, do the following:
1.
2.
Cut the DC output cord to the length needed.
Strip the jacket to expose 3/16" (5 mm) of the conductors.
Exposing more than the amount of copper wire
described above could allow the stripped wires to
touch each other, causing a short circuit. This could
result in the external DC power supply overheating
and/or burning.
W
Stripping the wires to expose less than the recommended
amount causes them to slide out of the connector too easily,
even if they are tightly pinched by the captive screws.
N
3.

5.
Slide the leads into the supplied captive screw plug and
lock them, using a small screwdriver.
Use the supplied tie-wrap to strap the power cord to the
extended tail of the connector.
To verify the power cord’s polarity before connecting
it, plug in the power supply with no load and check the

To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
When connecting the power supply, voltage polarity
is extremely important. Applying power with
incorrect voltage polarity could damage the power
supply and the interface. Identify the power cord

Adjusting the MP 101 D
Adjustment options for the MP 101 D are located on its rear
panel (see “Rear Panel Features” in this chapter for details).
Therefore, you must perform these adjustments before
mounting into a wall.
To adjust the MP 101 D, do the following:
1.
If using a condenser microphone, set the Phantom power
switch to the “on” position.
If using a dynamic microphone, set the Phantom power
switch to the “off” position.
2.
When using the microphone for voice audio, flip the Low
Cut switch to “on” to reduce wind and “table rumble”
noise.
When using the microphone for music audio, set the Low
Cut switch to “off” to preserve the optimum sound quality.
3.
Set the Mic Gain potentiometer by saying a few words into
the microphone and adjusting for the maximum sound
level that is free of distortion.
If there is a remote control connection, unplug it while
adjusting the Mic Gain potentiometer. Replace the remote
control when finished.
N
If there is minimal distortion, but greater volume is
required, turn the Mic Gain potentiometer clockwise
(towards the 75 dB mark) to increase the volume, but not
past the point where distortion occurs.
Mounting the MP 101 D
The MP 101 D provides the same features as the other
MP 101 models in a convenient, Decora style wallplate.

Architectural Installation
Installation Instructions
Two versions of the MP 101 series, the MP 101 AAP and
MP 101 D, can be mounted into furniture, a wall, or an
Ackermann floor box. For specific mounting instructions for
each model, see “Mounting the MP 101 AAP” in chapter 4, and
“Preparing the Site and Installing the Wall Box`” in chapter 5.
Unless otherwise noted, both units (the MP 101 AAP and the
MP 101 D) are referred to as the "MP 101" in the following
instructions.
The MP 101 must be installed into an Underwriters
Laboratories (UL) approved electrical wall box. The
box is not included with the MP 101; the installer is
responsible for obtaining and installing the box.
C
Preparing the Site and Installing the Wall Box
Choose a location that allows cable runs without interference.
Allow enough depth for both the wall box and the cables.
You may need to install the cables into the wall, furniture, or
conduits before installing the mic driver.
•
The MP 101 AAP can be installed into an HSA 400 Series
surface access enclosure, or into a two-gang or four-gang
wall box. Its faceplate accepts up to four single height
Extron Architectural Adapter Plates (AAPs).
•
The MP 101 D can be installed into a standard or compact
one-gang electrical wall box using the included Decora®
style wallplate.
The installation must conform to national and local electrical
codes and to the MP 101’s size requirements. Dimensional
drawings and a template for the MP 101 D are provided in
appendix B of this manual.
1.
For the MP 101 D only, see the template in appendix B. A
template is not required for the MP 101 AAP.
The template is not shown at full size. Pay attention to the
measurements shown on the template.
N
2.
Mark the guidelines for the opening on the wall or
furniture.
• If the MP 101 will be installed in a wall box, place the
box against the installation surface and draw a line on
it around the outside of the box.

• If the MP 101 will be installed without a wall box
(using mud rings or fastening it directly to the wall or
furniture), measure and mark the surface for the cutout
area indicated in the template.
3.
4.
Cut out the material from the marked area.
Check the opening size by inserting the wall box (if used)
or the MP 101 (if no box is used) into the opening. The
box and preamplifier should fit easily into the opening.
Enlarge or smooth the edges of the opening if needed.
5.
6.
Feed cables through the wall box punch-out holes, and
secure them with cable clamps to provide strain relief.
Exposed cable shields (braids or foil) are potential sources
of short circuits. Trim back and/or insulate shields with
heat shrink.
