MX400SE
Gooseneck Microphones
General Description
Shure Microflex MX400SE Series microphones are miniature gooseneck-mounted electret condenser microphones designed
primarily for speech and vocal pickup. Their high sensitivity and broad frequency range make them suitable for recording, as
well as sound reinforcement applications.
The MX400SE series can be screwed onto a mic stand or the supplied 5/8 in. 27-threaded flange. They can be easily changed
from side exit to bottom exit to conceal the cabling. All models include an in-line preamplifier, a 3.66 m (12 ft.) cable.
Wide dynamic range and frequency response for accurate sound reproduction
Interchangeable cartridges that provide a choice of polar pattern for each application
Shock mount provides over 20 dB of isolation from surface vibration noise
Snap-fit foam windscreen
RF filtering
Model Variations
MX400 microphones are available with 305 mm (12 in.) or 457 mm (18 in.) goosenecks, with or without a mute switch. They
are available in supercardioid, cardioid and omnidirectional polar patterns.
"S" models include a mute button and LED.
"D" models include a desktop base with programmable mute button and LED and logic input and output.
"SE" models feature a surface mount flange with side-exit cable.
The polar pattern of the included cartridge is indicated by a model number suffix:
/C Cardioid
/S Supercardioid
/O Omnidirectional
/N Cartridge not included

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.
Preamp Gain
If necessary, the preamplifier gain can be reduced by 12 dB. Contact an authorized Shure service center for information.
RFI Filtering
Important: Microphones must be used with the RK100PK or RK202PK plate-mounted preamp to optimize RF immunity.
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.
Permanent Installation
Changing from Side Exit to Bottom Exit
Do not cut the cable to reroute. This will compromise RF immunity.
Mount the microphone using one of the following methods.
Flange
Slip the mounting flange retaining ring over the bottom of the preamplifier and slide it up until it is flush to the bottom of the
flange. Then press the ring firmly into place.

Shock Mount
Drill a 44mm(1-3/4 in.) diameter hole in desired mounting surface.
Mark and drill starter holes for screws, using shock mount as a template.
Secure shock mount to mounting surface with screws.
Thread the supplied adapter onto the MX400SE microphone before inserting it into the shock mount.
