MODEL MX400 SERIES MICROPHONES
OVERVIEW
Shure MicroflexrMX400 Series microphones are miniature
gooseneck-mounted electret condenser microphones de-
signed primarily for speech and vocal pickup. They can be
mounted on lecterns, pulpits, or conference tables. All models
include a preamplifier and are available with interchangeable
cardioid, supercardioid, or omnidirectional cartridges.
FEATURES
SWide dynamic range and frequencyresponse for
accurate sound reproduction across the audio spectrum
SInterchangeable cartridges provide the right polar pattern
for every application
SBalanced, transformerless output for increased immunity
to noise over long cable runs
SShock mount that provides over 20 dB isolation from
surface vibration noise
SLocking flange mount for permanently securing
microphone to lecterns, pulpits, or conference tables
SSnap-fit foam windscreen
