Shure Microflex MX400SE Series User Manual

GENERAL
â
Shure Microflex MX400SE Series microphones are miniature
gooseneck-mounted electret condenser microphones designed for
speech and vocal pickup. Their high sensitivity and broad frequency
range make them suitable for recording, as well as sound reinforce-
ment applications.
MX400SE microphones can be screwed onto a mic stand or the
supplied 5/8 inch 27-threaded flange. They can be easily changed
from side-exit to bottom-exit to conceal the cable. All models include
an in-line preamplifier and a 3 m (10 ft) cable. Each microphone is
available with interchangeable cardioid, supercardioid, or omnidirec-
tional cartridges.
FEATURES
• Wide dynamic range and frequency response for accurate
sound reproduction across the audio spectrum
• Interchangeable cartridges that provide an optimal polar pat-
tern choice for each application
• Balanced transformerless output for increased immunity to
noise over long cable runs
• Supplied shock mount for more than 20 dB isolation from sur-
face transmitted noise
• Supplied threaded flange mount for permanently securing the
microphone to a lectern, pulpit, or conference table
• Snap-fit foam windscreen
MODEL VARIATIONS
All Microflex microphones are available with any one of three inter-
changeable cartridges. The polar pattern is indicated by the model
number suffix:
/C = Cardioid, /S = Supercardioid, /O = Omnidirectional
MX412SE/C, MX418SE/C: Recommended for general sound rein-
forcement applications. Pickup angle (-3 dB) = 130°.
MX412SE/S, MX418SE/S: Recommended for sound reinforcement
applications requiring narrow or more distant coverage. Pickup angle
(-3 dB) = 115°.
MX412SE/O, MX418SE/O: Recommended for recording or remote
monitoring applications. Pickup angle = 360°.
GENERAL INSTALLATION GUIDELINES
1. Aim the microphone toward the desired sound source, such as
the talker, and away from any unwanted sound source, such as a
loudspeaker.

Gooseneck Microphone User Guide
2. Place the microphone within 15 to 30 cm (6 to 12 in.) of the
desired sound source.
3. Always use the supplied foam windscreen or the optional metal
windscreen to control breath noise.
4. If four or more microphones will be open at the same time, use of
an automatic mixer, such as the Shure SCM810 or FP410, is rec-
ommended.
MICROPHONE INSTALLATION
Installing a Microphone onto a Threaded Flange
(Figure 1 on page 9)
1. Trace and drill three starter holes for the supplied screws using
the threaded flange as a template.
2. Secure the flange to the mounting surface using the three sup-
plied screws.
3. Thread the microphone onto the flange.
Installing a Microphone in a Shock Mount (Figure 2 on page 9)
1. Drill a 44 mm (1-3/4 in.) diameter hole through the mounting sur-
face in the desired location.
2. Trace and drill three starter holes for the screws using the shock
mount as a template.
3. Secure the shock mount to the mounting surface with three
screws.
4. Thread the microphone onto the supplied shock mount adapter
and insert the adapter into the shock mount.
Changing from Side Exit to Bottom Exit (Figure 3 on page 9)
1. Unscrew the preamplifier cap.
2. Loosen the retaining screw and push the XLR plug up until the cir-
cuit board screw terminals are accessible.
3. Remove the cable from the screw terminals, and slide the cap off
of the cable.
4. Push the outer threaded nut on the microphone back to access
the inner hex nut on the bottom of the gooseneck.
5. Unscrew the inner hex nut from the gooseneck. Then remove the
outer threaded nut.
6. Insert the cable through the outer threaded nut, then through the
inner hex nut.
7. Replace the outer threaded nut on the gooseneck.
8. Screw the inner hex nut back onto the gooseneck.
9. Install the flange mount or shock mount, and route the cable
though the center of the mount.
10. Reinsert the cable through the preamplifier cap.
11. Reconnect the cable to the preamplifier screw terminals (Red to
R; Black to B; Shield to S) and wrap the cable around strain relief
notches. Then screw the preamplifier cap back on tight.
Installing the Snap-Fit Foam Windscreen (Figure 4 on page 9)
1. Press the foam windscreen onto the microphone until it snaps into
the groove located below the cartridge.
2. To remove the windscreen, spread the gap in its mounting ring
with a screwdriver or thumbnail and pull the windscreen off care-
fully.
ADJUSTING PREAMP GAIN
This MX microphone includes an adjustable gain preamplifier, al-
lowing the user to specify a 12 dB or 0 dB gain setting. The preamp
ships at the 12dB setting. Gain may be decreased by 12dB by moving
the preamp jumpers to the 0dB setting.
