So as a practical learning tool I want to put together an audio switch that takes one input and switches between two outputs. They will all be those Red/White component connectors. Input will be from a WDTV (line level) and outputs will be to a Home Theater receiver and a headphone amp. I also want this switch to be remote, either wifi/bluetooth controlled from my android phone (prolly very hard/expensive but very cool) or IR (remote controller). As a 3rd option (if the other two are out of my reach or too expensive), I've also thought of running a wire and having a physical switch run about 20ft away from the AV switch. I'd have to run headphone wire anyways so ....
Anyway so I'm trying to get just the switching part designed and I am thoroughly confused. I'm thinking to use something like a CD4066 and a micro controller for the wireless portion.
I'm a bit confused on the input voltage of that switch. I know how to get a nice clean voltage for power from a wall wart but that would give me say a +5v and 0v ground. If I'm understanding this correctly then I would it to be +5v and -5v if my audio signal alternates between the two.
