Hi, was wondering if anyone knows a way to switch audio from one stereo to another. I am trying to build a sound board with 2 stereos and 2 speakers. The idea is to be able to turn  on the second stereo with a switch, and have audio cutoff  from the first stereo then go to the second stereo without any feedback to the first stereo. Any ideas  would be great, Thanks.

you would need to find a switch board.  one that does that automatically when th buttons are pushed.  something like you would find at your local audio shop.  they are used a bb, cc, frys etc. dont know where to pick one up though.

Here is a circuit for multiple displays. For 2 you could just use a couple of relays for each channel.
