Mute Button Configuration

Logic Wiring

NOTE: Bottom

cover must

be closed for microphone to function.

Use the DIP switches to configure logic settings and mute button behavior.

The DIP switches are covered with a piece of clear tape at the factory. Remove tape to modify the switch settings.

	OFF (factory	ON
	default)
1	Momentary	Toggle
2	Push-to-mute	Push-to-talk
3	Mute button enabled,	Disable mute button

4	--	--

Wiring Diagram

NOTE: Audio and logic ground are connected at microphone base.

Use DIP switches 1 and 2 to configure the mute button, as follows.

Be sure to set DIP switch 3 off (factory default) so that the mute button controls audio from the microphone.

Switch Function

DIP Switch Setting

Momentary: push-to-mute (as shipped).

Momentary: push-to-talk

Toggle: (Push On/Push

Off): Mic is active when powered on

Toggle: (Push On/Push

Off): Mic is mute when powered on

Connecting to an Automatic Mixer

Use these settings if connecting the microphone to an automatic mixer or other device that mutes audio and controls the LED.

1.Connect logic leads to the automatic mixer. Connect the LED IN to the gate output to illumi- nate the LED when that channel is gated on.

2.Set DIP switch 3 on. This disbles the mute but- ton (the microphone passes audio regardless of whether the button is pressed or not).

3.Set DIP switch 1 to configure how the mute but- ton sends SWITCH OUT logic:

Green (LOGIC GROUND): Connects to the logic ground of an automatic mixer, switcher, or other equipment.

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 but- ton to toggle the microphone (DIP switch 1 ON, 3 OFF):

1. Access the circuit board in- side the microphone base. 2. Remove the resistor at R45

and reinstall it at location R46.
