To operate the LED indicator, use the included 5-pin XLR con-  
nector 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.  
Note: Over tightening the wing nut reduces shock isolation.  
Attached Cable  
Do not use the relay ports on Crestron and AMX devices. Use the  
I/O logic ports instead.  
Caution: To prevent bending pins, line up key with notch and seat  
connector fully before twisting to lock.  
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  
instructions.

Function  
Audio +  
The microphone 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 when muted.

SWITCH OUT  
LED IN  
Set DIP Switch 3 up to configure the microphone for logic control  
applications where audio from the microphone is muted by an ex-  
ternal 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.  
In this configuration, the LED color reflects the microphone state,  
as controlled by the user with the PUSH button.

Logic Ground  
Mic Common Ground  
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 con-  
ductor, which signals the device to mute audio for that channel or  
perform some other function.
