MX400SE
Shure Microflex®MX400SE Series microphones are miniature goose-
neck-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 bot-
tom 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
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 supercar-
dioid, 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
Interchangeable Cartridges
Microflex microphones use interchangeable cartridges that allow you to
choose the polar pattern for different 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.
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 and 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
Flange
1. Drill a 22 mm (7/8 in.) diameter hole in the desired location.
2. Trace and drill three starter holes for the sup-
plied screws using the flange as a template.
3. Insert the preamplifier through the mounting flange.
4. Slip the mounting flange retaining ring over the bottom of
the preamplifier and slide it up until it is flush to the bot-
tom of the flange. Then press the ring firmly into place.
5. Secure the flange to the mounting surface with three screws.

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