MX392 Mic element active - LED controlled by switch

FAQ #3484 Updated July 01, 2015

Question:

I need the MX392 mic element to always active, but the LED to follow the action of the switch.  Can this be done?

Answer:

MX392 Modification

Mic element always active.  LED lights up only when switch is pushed.

1. Set internal DIP switch:

S1 = OFF - if SWITCH OUT logic signal needs to be momentary (push and hold)

OR

S1 = ON - if SWITCH OUT logic signal needs to be latching (push on/push off)

S3 = ON

S4 = OFF


2. Inside of the mic, insert a jumper wire between the LED IN screw terminal and the SWITCH OUT screw terminal. The SWITCH OUT terminal will now activate the LED whenever the mic membrane switch is activated.
