As required by the installation specifications, wire the SWITCH OUT conductor in the microphone cable to the au-
tomatic mixer or other TTL logic device. When the talker presses the button on the microphone, it changes the
voltage level at the SWITCH OUT conductor, 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).
Button Configuration
For logic control operation, DIP Switch 1 determines the button behavior (DIP Switch 2 has no effect).
Button Behavior
DIP Switch Setting
Momentary:
When pushed, SWITCH OUT (red wire) falls to 0 V. When released,

Toggle:
Push and release sets SWITCH OUT to 0 V. Push again to toggle back to +5
V.
Controlling the LED Using Logic LED IN
When configured for logic mute control, connect the LED IN conductors to an external switch, relay, or a TTL gate
(gate out) on an automatic mixer.
