So i've had my Denon AVR-791 for about 3 years now and other than the manual/menus, i've had no complaints. Great receiver. However, I recently moved my living space around and now I no longer get any sound from the center channel. I've hooked up 3 different speakers using a few different speaker wires and i've had no luck. All the speakers i'm using work fine when connected to other inputs.
The strange part is, when I run the test tone, I get feedback from whatever speaker is connected via the center channel input. The receiver seems to detect that there is a speaker connected, but when I go to adjust the channel levels, the "C" option is mysteriously missing. I also tried re-adjusting the amp output but no luck there, either.
I'm seriously baffled. I was ready to chalk it up as defective until I ran the test tone and I was able to get sound(it's a scratchy feedback that tells you how loud your speakers are) coming through whatever speaker I had connected to the center channel input.
I know many of you are far smarter and more experienced than me, so I was hoping by slim chance one of you could help me! I've searched but nobody else seems to have this issue that I can find. I would greatly appreciate some feedback. Thanks!
