Hello diyAudio family,
I require help regarding a project I am working on. I have a drive thru setup of my own where I have a base station microphone, the document says its a phantom powered microphone but with +18V, +18V and GND line instead of standard 48V phantom power. The current base station model doesn't support the recording feature so I decided to make my own. I am looking to tap the signals from the microphone and record them whenever a vehicle is present. I have done the tapping of the vehicle detect logic which is a simple relay logic turning on and off. But I am stuck in the microphone signals tapping phase. Can someone please guide me where should I start with? Your help will be highly appreciated.
