Orange (LED IN): Set DIP switch 3 on to use LED IN. When shorted to LOGIC GROUND, the LED turns on.
White (SWITCH OUT): Provides TTL logic (0 Vdc or 5 Vdc) in response to the mute button. Set DIP switch 1 for momentary or
toggle. When phantom power is applied, logic initializes high (5 Vdc). DIP switch 2 has no effect on SWITCH OUT.
Changing SWITCH OUT to Always Momentary
Use the following modification in situations where your logic interface requires momentary closure of the SWITCH OUT, but
you want the mute button to toggle the microphone (DIP switch 1 ON, 3 OFF):
Access the circuit board inside the microphone base.
Remove the resistor at R45 and reinstall it at location R46.
