Add 2nd TV & wireless speakers to Onkyo HT-S5100 7.1 Channel Receiver?
We have a 7-year old Onkyo HT-S5100 7.1 Channel Home Entertainment System in our living room. We're adding a TV and wireless speakers outside. Can use our existing receiver and connect it to the TV outside and project the sound through the wireless speakers? What do we need to make this happen? Or would we be better off getting an inexpensive AV receiver for outside and connecting the TV and wireless speakers to that? If so, can you recommend one?
