I'm beginning to wonder if the firmware in my 1066 has some bugs with regard to bass management. I was one of the people who verified that the 6.1 inputs had the “bass-doubling” issue. Now, I've noticed that the 1066 seems to have bass management issues in regular 2-channel as well.
I've found that if I set my mains to large, the subwoofer still gets a signal when playing music in 2-channel stereo. Basically, the "Yes" setting for the subwoofer in Speaker Setup seems to be having the same effect as the "Max" setting, which makes me wonder why they even have both. Now call me crazy, but doesn't that defeat the whole purpose of being able to set some of your speakers to large?
The only way I can get the subwoofer out of the picture is to go into the Speaker Setup screen and set Subwoofer to "No". Obviously that's not an acceptable solution since my other speakers need to be set as small.
Note, this testing was done using a coax digital connection, so this has nothing to do with the 2-channel analog bypass mode, which supposedly does have the bass-doubling problem. Since I'm giving the 1066 a digital signal that goes through the DSP, there is absolutely no reason I can think of that would make sense to send a full-range signal to large mains and still use the sub.
In the past when we were discussing the 6.1 inputs' bass-doubling issue, there was one person who claimed that his 1066 did not have this problem. This makes me wonder if Rotel has been playing around with the bass management code in the various software releases that have been made available. My 1066 has never been updated by me, and since it doesn't display the version number in the setup screen I assume it's running version 1.35. It would be helpful if some of you other 1066 users could perform the same test (digital input, 2-channel stereo, mains=large, sub=yes) and post not only your results but also your software version if you know what it is. Andrew, I'd also appreciate it if you could bring this thread to the attention of your contact at Rotel.
