Multi-Element Boundary Microphone
General Description
Shure MX396 Dual-Element and Tri-Element microphones provide
full coverage of large tables with fewer microphones, and feature a
low profile design. This makes them ideal for use in boardrooms and
other installations where aesthetics are important.
Features
• Low profile, aesthetic design
• Wide dynamic range and smooth frequency response
• Configurable mute switch with logic output
• Logic input for external LED control
• RF filtering with CommShield®technology
Placement
Important: Align the Shure logo as shown for proper coverage.

Reconfiguring the MX396-TRI for 360° Coverage
To configure the MX396 for 360° "omnidirectional" coverage, open the grille and reposition the internal mic elements as shown.
Permanent Installation
Note: Overtightening the wing nut reduces shock isolation.

Cable
The MX396 comes with a 20 ft. attached, unterminated cable.

Phantom Power
Each element in the microphone requires 12 to 48 V phantom power.
The LED also uses phantom power, and dims slightly when phantom
power voltage drops below 48 V DC.
The Tri-element model draws 22 mA at 48 V. The Dual-element mod-
el draws 19 mA at 48 Vdc. (Each element draws 3 mA and the LED
draws 13 mA, distributed equally among each element.)
NOTE: Do not connect multiple elements in parallel to a single mic
input. The phantom power current draw could exceed the maximum
allowable for one mic input.
Accessing the DIP Switches
Caution: Failure to reinstall the setscrew will reduce RF immunity.

Local Mute Control
The mircophone ships configured for local (manual) mute control
(DIP Switch 3 down). In this mode, the PUSH button on the micro-
phone mutes the audio signal at the microphone. Audio is not sent
to the audio outputs.
In this configuration, the LED color reflects the microphone state, as
controlled by the user with the PUSH button.
Green: microphone active
Red: microphone muted
Button Configuration
For local mute control operation, use DIP Switches 1 and 2 to configure the button behavior.
Button Behavior SWITCH OUT Logic Signal DIP Switch Setting
Momentary: push-to-mute (as
shipped).
When pushed, SWITCH OUT
(red wire) falls to 0 V. When re-
leased, SWITCH OUT returns
to +5 V.
Momentary: push-to-talk
Toggle: Push and release to
toggle the microphone on or
off. Mic is active when pow-
ered on.
Push and release sets
SWITCH OUT to 0 V. Push
again to toggle back to +5 V.
Toggle: Push and release to
toggle the microphone on or
off. Mic is mute when powered
on
Low Cut Filter
Set DIP Switch 4 up to activate the low cut filter. Attenuates 6 dB per octave below 150 Hz.

7
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 de-
vice, 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 sig-
nals 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).
Button Configuration
For logic control operation, DIP Switch 1 determines the button behavior (DIP Switch 2 has no effect).
Button Behavior DIP Switch Setting
Momentary: When pushed, SWITCH OUT (red
wire) falls to 0 V. When released, SWITCH OUT
returns to +5 V.
Toggle: Push and release sets SWITCH OUT
to 0 V. Push again to toggle back to +5 V.
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 LED illuminates green when the MX396 LED IN is grounded (black wire connected to the bare silver wire).
• The LED illuminates red when LED IN is lifted (black wire is NOT connected to the bare silver wire).
