I need help with switching one audio output between two sets of speakers.
To complete a project, I need to be able to switch one stereo audio output back and forth between two sets of speakers or headphones, (or be able to do something equivalent to this). I would like to be able to have one set of speakers playing the audio, and then at the push of a button or flip of a switch, switch the output to a second set of speakers. If there's something like this available commercially, my Google-fu hasn't been strong enough to locate it.
It would have to be fairly compact and portable.
Does anyone know where to buy something like this or how to make something that can do what I want? Any helpful suggestions?
Edit: This link has something that would work if it weren't (I suspect) grossly overpriced and somewhat oversized: electronicsusa.com/mk8.html
