Topic: Help with unmuting an input momentarily using GPIO and remote button
I am trying to figure out how to unmute an input (mic from our stage manger) using GPIO . The guys have a physical button and we would like to wire it to a GPIO so when the stage manager hits the button, it unmutes his annce mic to the house. I know, seems simple, but I can't figure out how to trigger the unmute when it senses the voltage or what not that will come in when they hit their remote button.
we were going to use the HCO pin so we could disable the power if needed and then use a GPIO for the return but it needs to sense the voltage and then trigger the unmute.
