MX400D Series microphones
are miniature electret condenser gooseneck mi-
crophones with a desktop base and a 3 m (10 ft.)
cable. Desktop base allows microphones to be
used in multi-purpose rooms where quick setup
is required, or where permanent installation is
impractical.
Features
• Wide dynamic range and frequency response
for accurate sound reproduction
• Interchangeable cartridges that provide a
choice of polar pattern for each application
• Programmable mute button and LED indicator
• Logic input and output terminals for remote
control or use with automatic microphone
mixers
• Balanced, transformerless output for increased
immunity to noise over long cable runs
• RF filtering
MX400 Series Model Variations
MX400 microphones are available with 305 mm
(12 in.) or 457 mm (18 in.) goosenecks.
• “S” models include a mute button and LED.
• “D” models include a desktop base with
programmable mute button and LED and logic

The polar pattern of the included cartridge is indi-
cated by a model number suffix:
/C Cardioid
/S Supercardioid
/N Cartridge not included
Interchangeable Cartridges
Microflex microphones use
interchangeable cartridges
that allow you to choose
the polar pattern for differ-
ent installations.
Snap-Fit Windscreen
• Snap into the groove
below the cartridge.
• To remove, spread
the gap with a
screwdriver or
thumbnail.
• Provides 30 dB of
“pop” protection.
Microphone Placement
• Aim the microphone toward the desired source,
such as the talker.
• Aim it away from any unwanted source, such
as a loudspeaker.
• Place the microphone within 15 to 30cm (6 to
12 in.) of the desired sound source.
• Always use the supplied windscreen or optional
metal windscreen to control breath noise.
• If four or more microphones will be open at
the same time, use of an automatic mixer,
such as the Shure SCM810 or SCM410, is
recommended.
