GENERAL
Models MX183, MX184, and MX185 are wired lavalier
electret condenser microphones designed for speech and
vocal pickup, general purpose sound reinforcement, record-
ing, and remote monitoring applications. They can be clipped
to neckties, lapels, and other articles of clothing. Interchange-
able cartridges make it possible to easily reconfigure micro-
phone coverage as the need arises.

sound reproduction across the audio spectrum
• Interchangeable cartridges that provide an optimal choice
for each application
• Rotatable tie-clip that pivots in 90_ increments for place-
ment flexibility
• Supplied snap-fit foam windscreen that controls breath

GENERAL RULES FOR LAVALIER MICROPHONE USE
1. Attach the lavalier microphone approximately 76 mm 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.
USING THE TIE CLIP
Insert the top of the microphone through tie clip loop from
below until tie clip loop snaps into place over the lower
groove on the microphone. Refer to Figure 1.
USING THE WINDSCREENS
Snap-fit windscreen: press it down on the microphone
until it clicks into place inside the upper groove on the micro-
phone. Provides 30 dB of "pop" protection.
NOTE: The snap-fit windscreen can be removed by
spreading the slot in the plastic snap-fit ring.
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.
CHANGING CARTRIDGES
The MX183, MX184, and MX185 microphones use inter-
changeable cartridges. To remove the cartridge, unscrew it
from the microphone body, as shown in Figure 2. Install the re-
placement cartridge by screwing it onto the microphone body.
