INTERNAL DIP SWITCH FUNCTIONS (FIGURE 5)

All MX392 and MX393 models have internal DIP switches that allow the user to change the behavior of the microphone

On/Off switch. To gain access to the logic terminals, remove the grille retainer screw, the grille retainer, foam screen, and grille, as shown in Figure 2.

NOTE: S4 is available for custom applications. When S4 is in the ON position, pad W4 is connected to pad W5 (see Figure 10).

MX392 LOGIC TERMINAL DEFINITIONS (Figure 6) LOGIC GND Terminal: Connects to the logic ground of an

automatic mixer, switcher, or other equipment. Can be modi- fied to prevent ground loops.

SWITCH OUT Terminal: Provides a TTL logic low when the membrane switch is pressed. This signal is available at all times for all switch settings. The Switch Out function pro- vides a momentary closure when S1 is Off and a latching clo- sure when S1 is On.

LED IN Terminal: Can be modified to remotely control the LED by flipping DIP switch S3 in the microphone to the ON position. As supplied, the LED IN terminal draws 5 Vdc. When this is shorted to the LOGIC GROUND terminal, the LED turns on.

MX392 LOGIC MODIFICATIONS

Open the microphone as shown in Figure 2.

Isolating Logic Ground from Audio Ground

1.Remove jumper R40 from the top of the circuit board.

2.Make sure LOGIC GND terminal connects to the logic ground of the automatic mixer, switcher, or other equip- ment.

Changing SWITCH OUT Terminal to Always Momentary

To accommodate interface equipment requiring momen- tary closure of the microphone (even when the desired mi- crophone function is latching on/off), proceed as follows:

1.Remove R45 from the top of the circuit board.

2.Reinstall R45 at location R46 on the top of the circuit board.
