You are correct. Onkyo is supposed to switch off the THX Re-EQ when you go to Audyssey Movie mode that already has a built-in roll off. I am surprised that they are not. I wonder if there is a buried setting in the menu that you can use to undo that link.
Thanks Chris! I have basically memorized the manual, and have a good grasp on the unit, and if there is a way to prevent Audyssey Movie & THX Re-EQ from interacting, I don't know about it. I was hoping that the 709 would do it internally, and just not show it on the display, but it was fairly noticeable once I cycled through Movie/Music/Thx Re-EQ-ON-Off with test sweeps and real world material, that it was not the case.
In a way it's good, because I like to listen to music with Audyessy in Music (flat) mode, and I used to have to manually switch from Movie mode, but now, I have all of my inputs set to Audyssey Music mode with THX Cinema & Re-EQ for movies, and then I get a flat response for music without having to change anything.
Yes, everything is fine.
