I have looked around in the forum and decided to post this question here...if there is a better place please let me know... I would like to do some in house demos for friends. Is there and a/b switcher that will support 2 or 3 recievers/amps and three to five 5.1 speaker set ups. Ideally I would like to be able to have everything pre programmed and wired to the point that all that would need to be done is set it in place( plug it in?) and hook the speakers up. Something simular to what you might see at a B&M store but a little more mobile.
