Installation Instructions
Two versions of the MLP 101 series, the MLP 101 AAP and
MLP 101 D, can be mounted into furniture, a wall, or an
Ackermann floor box. For specific mounting instructions for
each model, see "Mounting the MLP 101 AAP" in chapter 4, and
"Mounting the MLP 101 D" in chapter 5.
Unless otherwise noted, both units (the MLP 101 AAP and the
MLP 101 D) are referred to as the "MLP 101" in the following
instructions.
C
The MLP 101 must be installed into an Underwriters
Laboratories (UL) approved electrical wall box. The
box is not included with the MLP 101; the installer is
responsible for obtaining and installing the box.
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 MLP 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 MLP 101 D can be installed into a standard or
compact one-gang electrical wall box using the included
®
Decora
style wall plate.
The installation must conform to national and local electrical
codes and to the MLP 101's size requirements. Dimensional
drawings and a template for the MLP 101 D are provided in
appendix B of this manual.
1.
For the MLP 101 D only, see the template in appendix B.
A template is not required for the MLP 101 AAP.
N
The template is not shown at full size. Pay attention to the
measurements shown on the template.
2.
Mark the guidelines for the opening on the wall or
furniture.
•
If the MLP 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 MLP 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.
Cut out the material from the marked area.
4.
Check the opening size by inserting the wall box (if used)
or the MLP 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.
Connecting Shields.eps
5.
Feed cables through the wall box punch-out holes, and
secure them with cable clamps to provide strain relief.
6.
Exposed cable shields (braids or foil) are potential sources
of short circuits. Trim back and/or insulate shields with
heat shrink.

To prevent short circuits, cut back the outer foil shield
to the point where the cable exits the cable clamp.
Both braided and foil shields should be connected to
an equipment ground at the other end of the cable, as
shown above.
7.
Insert the wall box into the opening, and attach it to the
wall, stud, or furniture.
