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 pull­up resistor circuits can be added for each microphone. Visit www.shure.com/FAQ for de­
tailed instructions.
