Hi,
I’m trying to use one microphone to work with 2 separate devices (a PA and a 2-way radio). It would have two independent Push-to-Talk (PTT) switches to activate each device, so essentially, when you push one PTT you activate the mic with the PA and not the 2-way radio, if you push the other PTT, you would use the same mic with the 2-way radio and not the PA.
I designed a harness that feeds the audio MIC+/- from the microphone to both inputs of the devices, and 2 switches on different PTT circuits to each device. However, I’m concerned about noise because the MIC +/- from both devices are tied together. Is this a legitimate concern? Is there something out in the audio world that already does this?
Hope you can help!
thanks…
