Model MX1BP Preamplifier User Guide

27D3026 (Rev. 4)

Printed in U.S.A.

GENERAL

The MX1BP is a battery-powered preamplifier designed to be

used with Microflex

or other condenser microphones. It allows

use of these microphones in situations where phantom power is

not available.

FEATURES

• 4-pin mini connector allows use with a variety of condenser

microphones

• Power LED Indicator indicates power status to the pream-

plifier

• Mute/On switch attenuates microphone without turning off

preamplifier

• Belt clip allows mobility while using lavalier and headset

microphones

• Preamplifier operates on 9 V battery or phantom power

• Features 3.7 m (12 ft) cord with attached male XLR con-

nector

BATTERY INSTALLATION

1. Move the Mic Mute/On switch on preamplifier to the Mute

position.

2. Press down on the OPEN side of the battery compartment

cover, slide it back and flip it open.

3. Insert a 9 V battery as shown, observing proper battery polar-

ity (“+/-”). Close the battery compartment cover.

4. Move the Mic Mute/On switch on the preamplifier to

the On

position when ready to use the unit.

NOTE: A minimal power drain occurs while the 9 V battery is

installed. To conserve battery life, remove the battery when

preamplifier is not in use.

OPERATION

1. With the Mic Mute/On switch in the Mute position, plug the

microphone into the preamplifier's 4-pin mini connector.

(NOTE: The Power LED Indicator will remain lit in both the

Mute and On microphone modes.)

2. Plug the XLR cable from the preamplifier into the respective

audio device microphone input.

3. Switch the Mic Mute/On switch to the On position.

4. Adjust the gain level of the audio input device, if necessary.

INTERNAL LOW-CUT FILTER

The MXIBP has an internal low-cut filter. As shipped from the

factory, it attenuates 6dB per octave below 25 Hz. To change the

filter to attenuate 12dB per octave below 95 Hz, follow the instruc-

tions below:

1. Remove the three screws from the underside of the MX1BP.

2. Remove the plastic cover and lift the printed circuit board with

the attached faceplate up and out of the pack.

3. Turn over the printed circuit board and locate the jumper strad-

dling the first and second pins nearest the input jack. Reposi-

tion the jumper to straddle the second and third pins.

4. Re-assemble the MX1BP by re-seating the printed circuit

board and faceplate. Replace the plastic cover and the three

screws.

USE WITH PHANTOM POWER

The MX1BP can also be used in situations where phantom pow-

er is available.

Phantom power may be applied with a 9 V battery in place or re-

moved. With the battery installed, the MX1BP will silently and au-

tomatically switch to the battery reserve should phantom power

fail. Battery depletion will not occur while phantom power is ap-

plied.
