Hey guys. I have a Yamaha 5240 receiver. I hooked up some 125 watt JBL outdoor speakers to my "B" section. These speakers are outside by my pool, and I wanted to have sound from them without sound coming from any of my indoor speakers. Well, after pushing the "B" button, I got sound from the outdoor speakers, but I also got sound from my 2 rear surround sound speakers. How can I keep my indoor surround sound speakers the same and get sound from the outside speakers without any sound coming out of the indoor speakers??? Please help. Thanks Jack Pike.
