Shure MX405, MX410, and MX415 miniature
gooseneck microphones are suitable for boardrooms and other sites where aesthetics are important. Permanently mount them at conference tables
or lecterns using the MX400SMP surface mount, or
use the MX400DP moveable desktop base, which
includes a configurable mute button with logic
output. Also compatible with the MX890 wireless
desktop base.
Features
• Low profile, aesthetic design
• Choice of bi-color indicator or light ring
• Wide dynamic range and smooth frequency
response
• RF filtering with CommShield® technology
• Logic input for external LED control
Model Variations
These gooseneck microphones are available in
different lengths with a cardioid or supercardioid
cartridge and either a bi-color LED status indicator
or a light ring.
Coverage and Placement
• Cardioid: One microphone for one or two people.
• Supercardioid: One microphone for each person.

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.
Interchangeable Cartridges
Microflex microphones use interchangeable cartridges that allow you
to choose the polar pattern for different installations.

LED Logic
To operate the LED indicator, use the included 5-pin XLR connector to wire the microphone to an automatic mixer or other logic
device.
Note: Connect the LED IN to the gate output to illuminate the LED
when the channel is gated on.
Do not use the relay ports on Crestron and AMX devices. Use the
I/O logic ports instead.
The LED logic may not function when connecting to devices
that do not have internal "pull-up resistor" logic circuits, such as
ClearOne DSP products. External pull-up resistor circuits can be
added for each microphone. Visit www.shure.com/FAQ for detailed
instructions.

Local Mute Control
The microphone ships configured for local (manual) mute control
(DIP Switch 3 down). In this mode, the PUSH button on the microphone mutes the audio signal at the microphone. Audio is not sent
to the audio outputs when muted.
In this configuration, the LED color reflects the microphone state,
as controlled by the user with the PUSH button.

Logic Mute Control (Automatic Mixing)
Set DIP Switch 3 up to configure the microphone for logic control
applications where audio from the microphone is muted by an external device, such as an automatic mixer. In this mode, the local
mute function of the PUSH button is bypassed (the microphone
always sends audio) and the LED does not respond directly from
pushing the button.
As required by the installation specifications, wire the SWITCH
OUT conductor in the microphone cable to the automatic mixer or
other TTL logic device. When the talker presses the button on the
microphone, it changes the voltage level at the SWITCH OUT conductor, which signals the device to mute audio for that channel or
perform some other function.
To control the LED on the microphone, wire the LED IN conductor
to the gate output on the automatic mixer (or any TTL logic device).

For logic control operation, DIP Switch 1 determines the button behavior (DIP Switch 2 has no effect).

Controlling the LED Using Logic LED IN
When configured for logic mute control, connect the LED IN conductors to an external switch, relay, or a TTL gate (gate out) on an
automatic mixer. The MX400DB contains an internal pull-up resistor circuit.
• The LED illuminates green/red when the MX396 LED IN is
grounded (orange wire connected to the green wire).
• The LED illuminates red/off when LED IN is lifted (orange wire
is NOT connected to the green wire).
Preamp Gain
If necessary, the preamplifier gain can be reduced by 12 dB.
