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.
Important: Align the Shure logo as shown for proper coverage.
To configure the MX396 for 360° "omnidirectional" coverage, open the grille and reposition the internal mic elements as shown.
The MX396 comes with a 20 ft. attached, unterminated cable.

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 model 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.
Caution: Failure to reinstall the setscrew will reduce RF immunity.
|Mute button enabled, LED illuminates when mic is active||Disable mute button (microphone always on), logic controls LED|
|Full Frequency Range||6dB/octave Low Cut Filter|
Set DIP Switch 4 up to activate the low cut filter. Attenuates 6 dB per octave below 150 Hz.
The mircophone 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.
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
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 released, SWITCH OUT returns to +5 V.|
|Toggle: Push and release to toggle the microphone on or off. Mic is active when powered 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|
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).
|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.|
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.
