LED Logic
For models equipped with an LED, use the includ-
ed 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 il-
luminate the LED when the channel is gated on.
Do not use the relay ports on Crestron and AMX
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 connect-
ing 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. Vistit www.shure.
