Hi .... Please forgive the (hopefully) simple question but it has been a few years since I took basic electronics. I have a Yamaha 5.1 home theater receiver (RXV-795) and I would like to hook up two separate pairs of surround speakers (one pair next to the couch, one pair in the rear of the room). Is it OK to connect both sets of cables to the surround speaker outputs? Will I be putting undue strain on my amp or will I impede either pair's sound? If it helps in answering the question, one pair of surrounds are Definitive Tech BP8's and the other pair are Cambridge Soundworks In-Wall speakers. Any assistance or advice would be greatly appreciated. Thanks!
