I have a club that needs the following set up and I have no idea how to accomplish it. The have several TVs and want to access three sources with each TV. They have cable, satellite and karaoke. Right now I have it temporarily set up with a manual switcher that allows it to switch between cable, satellite and karaoke. In other words they can either have cable on all of the TVs, satellite or karaoke. I have seen other bars that have the TVs individually switchable. Can you tell me how this is done. I figure I should be replacing the three way switch with something else but I have no idea what.
