I'm looking to set up a small home theater. I would like to set up all my devices to one set of 5 speakers that I bought. Is there a device that will allow me to control and turn off the speakers while still allowing the TV for example to still play through it's speakers, or letting the DVD player connect to the TV and play sound while the device is off? I would like to set my boom box (Which only has a speaker connection) My DVD player and my TV player all to the same set of speakers. Is this possible?
