I recently bought an ONKYO AV receiver TX-NR555 and I have very little knowledge about audio tech. I bought the receiver to hook up bedroom in ceiling speakers and outdoor speakers to play music. I have no intention on hooking up a tv, dvd, gaming console or any other device to the receiver, strictly music. My question is do I still need to hook the receiver to a tv to do my initial setup because right now my outdoor speakers are connected to the front right and left and work fine but my bedroom speakers connected to zone two right and left dont work. need help!!!
