I can turn them off via on-screen display! and then turn them back on via on screen display, when I need to. I wanted to cut off all channels except l+r surrounds for sleeping because I can't do it any other way and the neighbours can even get disturbed by just the centre being on sometimes. Thanks for the help. There's only 2 chnl streo or 7 chnl stereo and the unit will go to 1,2,3,4,5,6, channel stereo instead of 7 channel stereo because it reads what speakers are plugged in and only utilizes them, so bmxtrix it actually does what you were saying there and I can turn them on or off(regardless of what's plugged in or what the machine reads) so there's actually no downfall at all, and you guys helped me figure that out, I didn't realize that, so I owe you guys a coffee. Thanks.
