Just thought that I'd post my findings from reading my Denon manual. Denon's are made in Japan so if you read the manual keeping in mind how a Japanese visitor to the U.S. might talk to you in English, understanding the manual becomes much, much easier!
Why they didn't get a better translation from Japanese to English like Sony or from Korean to English like Samsung I suppose I will never know. But now that I've figured it out the manual has become quite clear to me.
