MODEL MX183, MX184, MX185 MICROPHONES
OVERVIEW
Models MX183, MX184, and MX185 a re w i r ed l a v a li e r
electret condenser microphones designed for speech and
vocal pickup, general purpose sound reinforcement, recording, and remote monitoring applications. They can be clipped

to neckties, lapels, and other articles o f clothing. I nterchangeable cartridges make it possible to easily reconfigure microphone coverage as the need arises.
FEATURES
S Wide dynamic range and frequency response for accurate
sound reproduction across the audio spectrum
S Interchangeable cartridges that provide an optimal choice
for each application
S Rotatable tie-clip that pivots in 90_ increments for place-
ment flexibility
