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 pos-
sible to easily reconfigure microphone coverage as the need
arises. The supplied MX1BP battery-powered preamplifier al-
lows use of these microphones in situations where phantom pow-
er is not available.
FEATURES

_
increments for placement
flexibility
•
Supplied snap-fit foam windscreen that controls breath noise
and stays on securely
•
Balanced transformer output for increased immunity to noise
over long cable runs
•
Supplied dual tie clip holds two microphones for dual miking
applications

APPLICATIONS
MX183BP (Omnidirectional): Recommended for general
purpose sound reinforcement, recording, or remote monitoring
applications. Pickup angle = 360
°
.
MX184BP (Supercardioid): Recommended for sound rein-
forcement applications requiring high rejection of ambient noise
and narrow pickup angle. Use of windscreen is highly recom-
mended. Pickup angle (–3 dB) = 115
°
.
MX185BP (Cardioid): Recommended for general purpose
sound reinforcement applications requiring good rejection of
ambient noise. Use of windscreen highly recommended. Pick-
up angle (–3 dB) = 130
°
.
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 mi-
crophone until it clicks into place over the upper groove on
the microphone. The snap-fit windscreen provides 30 dB
of “pop” protection.
NOTE: The snap-fit windscreen can be removed by spread-
ing the slot in the plastic-fit ring. To install the smaller foam
windscreen, slip the windscreen over the top of the micro-
phone 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 2.
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 bat-
tery is installed. To conserve battery life, remove the bat-
tery when preamplifier is not in use.
