So I finally hooked up my SACD player's 6-channel output to my Marantz SR-7000's 6-channel input. I pressed the 6-channel button on the front panel of the SR-7000, the sound is fine, everything seems ok. But when I try to use the remote to change sources it stays stuck on 6-channel no matter what source I try to switch to. The display panel on the SR-7000 just blinks a few times and remains in 6-channel mode. I have to press the 6-channel button before I can switch to anything else. Does anybody have the same problem or have a solution?
