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 de
tailed 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.

Toggle: Push and release to toggle the mi
crophone on or off. Mic is mute when

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 mi
crophone 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).
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 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).
