When I first got into home theater, some 17 years ago, it was early in the digital age of AV. What interested me was the DVDs with 5 discrete digital audio channels. Their sound was noticeably better than AV audio systems I'd heard before.
When I first got an AVR and DVD player, it took me some time to feel comfortable with the transition from the rather simple 1970s analog gear and 2 channel sound to the modern digital receiver and the 5 (or more) channel sound. I found the owners manuals from Denon to be especially obtuse. They did a poor job explaining what the new functions of the digital AVR were. It wasn't immediately obvious, and I think all of us have been there.
So, I don't have any problem with DCS0760's apparent difficulty in understanding the intended use of modern AV receivers, even though it is 2017 and not 2000. I can't criticize DCS0760 for not knowing what I also once didn't know. However, I do fault his remarkable resistance to learning what AVRs are intended to do and can do. Instead he seems to prefer his own spin on things, no matter how bizarre it seems to the rest of us.
Finally, his unusual language constructions don't help us understand what he is trying to say. (I could be wrong, but it does seem that English is DCS0760's native language.) Perhaps he has the same resistance to standard grammar and word usage that he also has to standard AV acoustic layout ideas.
