most Extron audio and switcher systems.

The MP 101 is rack-mountable, while the MP 101 AAP is an

AAP plate option for easy integration into Extron architectural

products. The MP 101 D works similarly to the other two units,

but features a Decora

wallplate mounting option. Information

on its installation and operation are found in chapter 4, “The

MP 101 D”.

Each model features a recessed Mic Gain potentiometer that

provides a 25 to 72 dB adjustment range, compensating for

different microphone sensitivities. Each model also features an

on/off switch for 48 volt phantom power and low cut ﬁ ltering.

Remote control is available through optional Extron VCM 100

AAP/MAAP panels, which control volume and muting.

Features

Compact size — The MP 101 is housed in a 1U high, 1/8 rack

width, 3" deep, metal enclosure, the MP 101 AAP is

housed in a two-space AAP plate; and the MP 101 D is

mounted into a wallplate. These three options allow for

diverse applications.

Quick plug input and outputs — Connectors are captive screw

or XLR (MP 101 AAP and MP 101 D only) for quick

installation.

Gain control — Provides a wide gain adjustment range of 25 to

72 dB.

Switchable low cut ﬁ lter — Provides low cut ﬁ lter to remove

wind and “table rumble” noise.

Switchable phantom power — Provides 48 volt phantom power

for condenser microphones.

Volume and mute remote control — Each model can be

remotely controlled for volume adjustment and muting

via a rear panel Remote connector.

Power — Plug the external 12 VDC power supply into this

2-pin, 3.5 mm captive screw connector. The power supply is

included with the unit.

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.

To wire the connector, do the following:

1. Cut the DC output cord to the length needed.

2. 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.

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.

3. Slide the leads into the supplied captive screw plug and

lock them, using a small screwdriver.

4. Use the supplied tie-wrap to strap the power cord to the

extended tail of the connector.

5. To verify the power cord’s polarity before connecting

it, plug in the power supply with no load and check the

output with a voltmeter.

The following ﬁ gure shows how to wire the connector.

Do not tin the stripped power supply leads before

installing the captive screw connector. Tinned wires

are not as secure in the captive screw connectors and

can be easily pulled out. They may also break after

being bent several times.

The two power cord wires must be kept separate while

the power supply is plugged in. Remove power before

wiring.
