ATTENTION:
• The DC output cables must be kept separate from each other while the power
supply is plugged in. Remove power before wiring
• Les câbles de sortie CC doivent être séparés les uns des autres tant que la
source d’alimentation est branchée. Coupez l’alimentation avant d’effectuer les
raccordements.
• Do not connect power to the amplifier until you have read the ATTENTION
notifications.
• Ne branchez pas l’alimentation au l’amplificateur avant d’avoir lu les mises en garde
« ATTENTION ».
• Always use a power supply supplied or specified by Extron. Use of an unauthorized
power supply voids all regulatory compliance certification and may cause damage
to the supply and the end product.
• Utilisez toujours une source d’alimentation fournie ou recommandée par Extron.
L’utilisation d’une source d’alimentation non autorisée annule toute certification de
conformité réglementaire et peut endommager la source d’alimentation et l’unité.
• If not provided with a power supply, this product is intended to be supplied by a
power source marked “Class 2” or “LPS” and rated at 12VDC and a minimum of
0.5A.
• Si le produit n’est pas fourni avec une source d’alimentation, il doit être alimenté par
une source d’alimentation de classe 2 ou LPS, avec une tension nominale 12 Vcc,
0,5 A minimum.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.
• Cette installation doit toujours être conforme aux dispositions applicables du Code
américain de l’électricité (National Electrical Code) ANSI/NFPA 70, article 725, et
du Code canadien de l’électricité, partie1, section16. La source d’alimentation ne
devra pas être fixée de façon permanente à une structure de bâtiment ou à une

• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the unit. The ridges on the side of the cord (see figure2 on the
previous page) identify the power cord negative lead.
• La polarité de la source d’alimentation est primordiale. Une polarité incorrecte
pourrait endommager la source d’alimentation et l’unité. Les stries sur le côté
du cordon (voir figure2) permettent de repérer le pôle négatif du cordon
d’alimentation.
• To verify the polarity before connection, plug in the power supply with no load and
check the output with a voltmeter.
• Pour vérifier la polarité avant la connexion, brancher l’alimentation hors charge et
mesurer sa sortie avec un voltmètre.
MP 101 Series • MP 101 Series Rear Panels 3
ATTENTION:
Slee
(high impedance)
• The length of the exposed (stripped) wires is important. The ideal length is
3/16inch (5mm). Any longer and the exposed wires may touch, causing a short
circuit between them. Any shorter and the wires can be easily pulled out even if
tightly fastened by the captive screws.
• La longueur des câbles exposés est primordiale lorsque l’on entreprend de les
dénuder. La longueur idéale est de 5mm (3/16inches). S’ils sont trop longs, les
câbles exposés pourraient se toucher et provoquer un court circuit. S’ils sont trop
courts, ils peuvent être tirés facilement, même s’ils sont correctement serrés par les
borniers à vis.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling
spaces or in wall cavities.
• Sauf mention contraire, les adaptateurs CA/CC ne conviennent pas à une utilisation
dans les espaces d’aération ou dans les cavités murales.
• Remote power is intended for indoors use only. No part of a network that uses
remote power can be routed outdoors.
• L’alimentation à distance est exclusivement réservée à un usage en intérieur. Un
réseau utilisant une alimentation à distance ne peut pas être routé en extérieur.

Mounting the MP 101
There are many optional accessories for mounting the MP 101 (see accessories on
the MP101 page of the Extron website). The following Underwriters Laboratories (UL)
guidelines pertain to the safe installation of the MP 101 in a rack.
UL Rack Mounting Guidelines
1. Elevated operating ambient temperature — If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment can be greater
than room ambient temperature. Therefore, install the unit in an environment compatible
with the maximum ambient temperature (Tma = +122°F, +50°C) specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when
addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (for example: use of power strips).

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,
Decorator-style wallplate.
NOTE: Before mounting, the MP 101 D should be tested to verify that its connections
and settings are correct.
To mount the MP 101 D into a Decorator-style faceplate, do the following:
1. Secure all cables and connections onto the MP 101 D.
2. If it was not done previously, adjust the MP 101 D from its rear panel (see Adjusting
the MP 101 D on the previous page for detailed instructions).
3. Place the MP 101 D through the opening in the wall or furniture and into the wall box.
Take care not to damage the output cables, which fit behind the preamplifier at the back
of the wall box.
4. Attach the Decorator-style wallplate to the MP 101 D, as shown below.

Architectural Installation
Topics covered in this section are:
• Installation Instructions
• Preparing the Site and Installing the Wall Box
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 a floor box. 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.
ATTENTION:
• 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.
• Le MP 101 doit être installé dans un boîtier mural électrique homologué UL
(Underwriters Laboratories). Le boîtier n’est pas fourni avec le MP 101 ; il incombe à
l’installeur d’obtenir et d’installer le boîtier.
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 Decorator-style wallplate.
The installation must conform to national and local electrical codes and to the MP 101
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 on page19. A template is not required for
the MP101AAP.
NOTE: The template is not shown at full size. Pay attention to the measurements
shown on the template.
MP 101 Series • Architectural Installation 15
2. Mark the guidelines for the opening on the wall or furniture.
Connecting Shields.eps
Foil Shield
• 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. Cut out the material from the marked area.
4. 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. 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.

ATTENTION:
• To prevent short circuits, cut back the outer foil shield to the point where the
cable exits the cable clamp.
• Afin d’éviter les courts-circuits, réduisez le blindage en aluminium extérieur
jusqu’à ce que le câble sorte de la cosse de câble.
• Both braided and foil shields should be connected to an equipment ground at
the other end of the cable, as shown above.
• Les blindages tressés et en aluminium devraient être connectés à la masse d’un
équipement à l’autre bout du câble, comme illustré ci-dessus.

7. Insert the wall box into the opening, and attach it to the wall, stud, or furniture.
Installation Cab
• If the MP 101 AAP or MP 101 D are being installed in a two- or four-gang AAP
plate, attach the wall box to the wall stud or furniture with nails or screws, leaving
the front edge flush with the outer wall or furniture surface. See the illustration
below, which applies to one-, two-, three-, and four-gang wall boxes.
