Shure Microflex MX400SE Serie Manual De Instrucciones

GENERAL

Shure Microflex MX400SE Series microphones are miniature
gooseneck-mounted electret condenser microphones designed
for speech and vocal pickup. Their high sensitivity and broad fre-
quency range make them suitable for recording, as well as sound
reinforcement 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 in-
clude an in-line preamplifier and a 3 m (10 ft) cable. Each micro-
phone is available with interchangeable cardioid, supercardioid, or
omnidirectional cartridges.
FEATURES
•
Wide dynamic range and frequency response for accurate
sound reproduction across the audio spectrum
•
Interchangeable cartridges that provide an optimal polar
pattern 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
surface transmitted noise
w
Supplied threaded flange mount for permanently securing the
microphone to a lectern, pulpit, or conference table
•
Snap-fit foam windscreen

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.
2. Place the microphone within 15 to 30 cm (6 to 12 in.) of the de-
sired sound source.
3. Always use the supplied foam windscreen or the optional met-
al 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 recommended.
MICROPHONE INSTALLATION
Installing a Microphone onto a Threaded Flange (Figure 1)
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)
1. Drill a 44 mm (1-3/4 in.) diameter hole through the mounting
surface 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 adapt-
er and insert the adapter into the shock mount.
Changing from Side Exit to Bottom Exit (Figure 3)
1. Unscrew the preamplifier cap.
2. Loosen the retaining screw and push the XLR plug up until the
circuit 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)
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
carefully.
