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
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.
