Shure Microflex MX400 Series microphones are miniature
gooseneck-mounted electret condenser microphones designed
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.
MX400SE models feature a side exit, 3 m (10 ft) cable and
in-line preamplifier. They can be easily changed from sideexit
to bottom-exit to conceal the cable.
FEATURES
Wide dynamic range and frequency response for accurate
sound reproduction across the audio spectrum
Interchangeable cartridges that provide the optimal polar
pattern for any application
Balanced, transformerless output for increased immunity
to noise over long cable runs
