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 12VDC and a minimum of

0.5A.

• 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, partie1, section16. La source d’alimentation ne

devra pas être fixée de façon permanente à une structure de bâtiment ou à une

structure similaire.

• 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 ﬁgure2 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 ﬁgure2) 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 4

ATTENTION:

• The length of the exposed (stripped) wires is important. The ideal length is

3/16inch (5mm). 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 5mm (3/16inches). 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.

Power LED (MP 101 only) (see figure1 on page2) — This LED lights green to

indicate that the unit is receiving power.

Remote Connection

Mounting the MP 101

There are many optional accessories for mounting the MP 101 (see accessories on

the MP101 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).

MP 101 Series • MP 101 7

Adjusting the MP 101

After the MP 101 has been properly mounted and connected, do the following to adjust it:

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, flip 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.

NOTE: If there is a remote control connection, unplug it while adjusting the Mic Gain

potentiometer. Replace the remote control when finished.

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.

Remote Control

The wiring and control options described below pertain to all models in the MP 101 series.

Remote Connector Wiring

As shown below, Pin 1 is 10 VDC reference voltage. Pin 2 is volume control DC voltage;

range is 0 to 10 V, where 0 V is mute and 10 V provides maximum volume. Pin 3 is ground.

5. If it was not done previously, adjust the MP 101 AAP from its rear panel (see Adjusting

the MP 101 AAP on the previous page for detailed instructions).

6. Pretest the MP 101 AAP before final mounting of the faceplate.

7. Perform the final mount by attaching the cabled device faceplate or AAP wallplate into

a wall or piece of furniture. For detailed installation information, refer to the installation

guide shipped with the faceplate.

Remote Control Options

The MP 101 AAP has three remote control options:

1. The Extron VCM 110 AAP volume/mute controller, VCM 200 Series volume/mute

controller, VC 50 volume controller, MLC 55 RS VC, and MLC 64 RS VC D and VC 50

volume controller use a 10 k ohm potentiometer as the main method for controlling

volume levels.

The VCM 110 AAP mute button overrides the mute button of the MP 101 D.

2. The Extron MLA-VC10 Plus converts RS-232 serial command to 0 to 10 volt variable

DC for volume control.

3. Generic volume/mute controllers are standard 10 k ohm potentiometers.

MP 101 D

The Extron MP 101 D provides the same features as the other MP 101 models in a

convenient, Decorator-style wallplate. Like the MP 101 and MP 101 AAP, this mic to line

preamplifier can be remotely controlled via a VCM volume/mute control module.

Topics covered in this section are:

• Front Panel Features • Mounting the MP 101 D

• Remote Control

Front Panel Features

Active LED — This LED lights green to indicate that

the unit is receiving power.

Mute LED — This LED lights red to indicate mute.

Mic Gain — A recessed, adjustable potentiometer

defines the amount of input signal (between 25 and

72dB) allowed into the preamp.

This potentiometer is covered by a plastic cap to

avoid tampering. To adjust the potentiometer, use

a small screwdriver to remove the covering, make

adjustments, then replace the cap.

XLR mic input — An XLR connector for a standard

microphone connection.

Adjusting the MP 101 D

Adjustment options for the MP 101 D are located on its rear panel (see Front Panel

Features). 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.

NOTE: If there is a remote control connection, unplug it while adjusting the Mic

Gain potentiometer. Replace the remote control when finished.

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,

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.
