Running surround sound speaker system through this tuner? Is anyone running surround sound speaker system through this tuner? I just need a basic tuner that gives me remote volume and control and on/off capability since my surround sound system has neither of these accessible by remote. I have my TV, cable box, game systems and DVD all going through my surround sound speakers via a switchbox which is then output to the speakers. The problem is that my surround sound speaker system doesn't have a remote and on/off switch is way in the back and hard to get to. I would like to run the output of the switch box to this tuner and then run the output of the tuner to the surround sound system so I can control the volume and on/off via this tuner. All that being said I just want to make sure I'll still get all 5 speakers and subwoofer receiving their appropriate sound outputs since they will be running through the tuner. Will this tuner do that for me?
