Shure MX183BP User Manual

GENERAL
Models MX183BP, MX184BP, and MX185BP are wired lavalier
electret condenser microphones designed for speech and vocal
pickup. They can be clipped to neckties, lapels, and other articles
of clothing. Interchangeable cartridges make it possible to easily
reconfigure microphone coverage as the need arises. The sup-
plied MX1BP battery-powered preamplifier allows use of these mi-
crophones in situations where phantom power is not available.

Wired Lavalier Microphones
GENERAL RULES FOR LAVALIER MICROPHONE USE
1. Attach the lavalier microphone approximately 76 to 152 mm
(3 to 6 in.) below the neckline for the best sound.
2. Do not cover the microphone with your hand or clothing.
3. Use one of the supplied windscreens to minimize wind
and breath noise.
4. If four or more microphones will be active at any given
time, use of an automatic mixer, such as the Shure
SCM810 or FP410, is recommended.
TIE CLIP AND WINDSCREEN INSTALLATION
1.
Insert the top of the microphone through tie clip loop from be-
low until tie clip loop snaps into place over the lower groove on
the microphone. Refer to Figure 1.
2.
To install the snap-fit windscreen, press it down on the micro-
phone until it clicks into place over the upper groove on the mi-
crophone. The snap-fit windscreen provides 30 dB of "pop"
protection.
NOTE: The snap-fit windscreen can be removed by spreading the
slot in the plastic-fit ring. To install the smaller foam windscreen,
slip the windscreen over the top of the microphone so that it covers
the side slots. The foam windscreen provides 5 to 10 dB of "pop"
protection.
MX1BP BATTERY INSTALLATION
1. Move the Mic Mute/On switch on the preamplifier to the Mute
position.
2. Press down on the OPEN side of the battery compartment
cover, slide it back and flip it open. Refer to Figure .
3. Insert a 9 V battery, observing proper battery polarity ("+/-").
Close the battery compartment cover.
4. Move the Mic Mute/On switch on the preamplifier to the On
position when ready to use the system.
NOTE: A minimal power drain occurs while the 9 V battery is in-
stalled. To conserve battery life, remove the battery when pream-
plifier is not
in use.
