Shure Microflex® MX400D Series microphones
are miniature electret condenser gooseneck mi-
crophones 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.
Features
• 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 automatic microphone
mixers
• Balanced, transformerless output for increased
immunity to noise over long cable runs
• RF filtering
MX400 Series Model Variations
MX400 microphones are available with 305 mm
(12 in.) or 457 mm (18 in.) goosenecks.
• “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 indi-
cated by a model number suffix:
/C Cardioid
/S Supercardioid
/N Cartridge not included
Interchangeable Cartridges
Microflex microphones use
interchangeable cartridges
that allow you to choose
the polar pattern for differ-
ent 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.
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.

Connecting to an Automatic Mixer
Use these settings if connecting the microphone
to an automatic mixer or other device that mutes
audio and controls the LED.
1. Connect logic leads to the automatic mixer.
Connect the LED IN to the gate output to illumi-
nate the LED when that channel is gated on.
2. Set DIP switch 3 on. This disbles the mute but-
ton (the microphone passes audio regardless of
whether the button is pressed or not).
3. Set DIP switch 1 to configure how the mute but-
ton sends SWITCH OUT logic:
Logic Wiring
Green (LOGIC GROUND): Connects to the logic
ground of an automatic mixer, switcher, or other
equipment.
Orange (LED IN): Set DIP switch 3 on to use LED
IN. When shorted to LOGIC GROUND, the LED
turns on.
White (SWITCH OUT): Provides TTL logic (0 Vdc
or 5 Vdc) in response to the mute button. Set DIP
switch 1 for momentary or toggle. When phantom
power is applied, logic initializes high (5 Vdc). DIP
switch 2 has no effect on SWITCH OUT.
DIP Switches
Use the DIP switches to configure logic settings
and mute button behavior.
The DIP switches are covered with a piece of
clear tape at the factory. Remove tape to modify
the switch settings.

Momentary
Use the following modification in situations where
your logic interface requires momentary closure
of the SWITCH OUT, but you want the mute but-
ton to toggle the microphone (DIP switch 1 ON, 3
OFF):
1. Access the circuit board in-
side the microphone base.
2. Remove the resistor at R45
and reinstall it at location
R46.
Mute Button Configuration
Use DIP switches 1 and 2 to configure the mute
button, as follows.
Be sure to set DIP switch 3 (factory default) off
so that the mute button controls audio from the
microphone.
Switch Function DIP Switch Setting
Momentary: push-to-mute
(as shipped).
Momentary: push-to-talk
Toggle: (Push On/Push
Off): Mic is active when
powered on
Toggle: (Push On/Push
Off): Mic is mute when
powered on
Momentary:
push = 0 Vdc,
release = 5 Vdc
Toggle:
initial = 5 Vdc,
push = 0 Vdc
