Caution: To prevent bending pins, line up key with notch and seat
connector fully before twisting to lock.
Cable
The 20 ft. attached cable is terminated with a 3-pin XLR connector.
For logic applications, open the XLR connector to access the three
unterminated logic conductors.

Local Mute Control
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

Button Configuration

For local mute control operation, use DIP Switches 1 and 2 to con-
figure the button behavior.

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 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.
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.
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).
