Where can I buy a premade vox / PA-style voice-override circuit? Answered
I have a pair of hearing protection headphones. I want to play radio & walkie-talkie through them. However, when the walkie talkie plays, I want the radio to cut out.
This is a basic PA-style circuit. Some sound mixers have this too. I can find circuit schematics online, but no time to build a circuit.
Is there a pre-made device I can buy to do this? Ideally it'd be a small box with 3 audio jacks - 2 inputs & 1 output. One of the audio inputs would override the other.
This would also be great for things like music + GPS in the car. Is there something premade that I can buy? I'd rather not have to build & debug a DIY circuit, as I really don't have the time right now.
