I was watching a show on Amazon Prime through my Roku last night and was having problems with the dialog. I tried Dynamic EQ with a -10 reference offset, Dynamic Volume on Light, Audyssey on Reference and flat and off. I couldn't get it to something I found satisfactory.
The problem was that every time surround information became somewhat more active, the center channel dialog receded -- and I don't mean just got covered up by the surrounds (which it did), but actually seemed to get softer as if there wasn't enough power going to it and the volume pulled back. I tried turning up the center channel volume/trim, but it actually was too loud on some passages and then would get too soft on others. I was only watching at around -22 - -25 db, and there is plenty of power given my space, so that really shouldn't be a problem.
I need to continue to do more experimenting, and it is possible it was even something peculiar to the mix of that show, but is there anything you can think of that I should change in settings or try? I want to make sure that there isn't something wrong with the unit.
Thanks.
