MODEL MX400 SERIES MICROPHONES

OVERVIEW

Shure Microflexr MX400 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 frequency response 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
