Low-Profile Boundary Microphone
MX395 Low-Profile Boundary
Microphone
General Description
Shure®MX395 low-profile microphones are for use
in boardrooms and other sites where aesthetics
are important. The MX395 is only 2.5 cm (1 in.) in
diameter, and extends just 2 cm above the mount-
ing surface when installed. Despite its small size,
the MX395 delivers clear, high quality sound.
Features
• Low profile, aesthetic design
• Wide dynamic range and smooth frequency
response
• RF filtering with CommShield®technology
• Available with logic-controlled bi-color status
indicator
Model Variations
The MX395 is available in cardioid, omnidirection-
al, and bidirectional polar patterns, with or without
an LED status indicator, with a black, white, or
aluminum finish.

Polar Patterns

Microphone Placement
For best low-frequency response and rejection
of background noise, place the microphone on a
large, flat surface, such as a floor, table, or lectern.
To reduce reverberance, avoid reflective surfaces
above or to the side of the microphone, such as
beveled sides of pulpits or overhanging shelves.
Installation
Install the microphone into a tabletop as shown.
Important:
• Align indentation toward talker
• Do not over tighten the wing nut, as this reduces
shock isolation
DIP Switches
Set DIP Switch 1 up to engage the low cut filter,
which attenuates frequencies by 6 dB per octave
below 150 Hz.

LED Logic
For models equipped with an LED, use the includ-
ed 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 il-
luminate 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 resis-
tor" logic circuits, such as ClearOne DSP products.
External pull-up resistor circuits can be added for
each microphone. Vistit www.shure.com/FAQ for
detailed instructions.
