MX400D Series microphones are miniature electret
condenser gooseneck microphones 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.
• 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 automat-
ic microphone mixers
• Balanced, transformerless output for increased immunity to noise over
long cable runs
• RF filtering
Desktop Microphones
MX400 microphones are available with 305 mm (12 in.) or 457 mm (18 in.)

dioid, cardioid and omnidirectional polar patterns.
• "S" models include a mute button and LED.

LED and logic input and output.

Cartridge Polar Patterns
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.
Securing to a Surface
Drill two holes in the mounting surface 50.8 mm (2 in.) apart.
Use #6-32 screws to secure the microphone.
