There just should not be a 10db swing of bass levels when the processor goes from a matrix surround mode (PL2,DTS Neo) to a digital surround mode (Dolby 5.1, DTS. I have no analog sources input to my system and levels change anytime the source changes from 2.0 to 5.1
I was able to confirm it by using an analog input, a test generator, a meter and my ears.

During initial setup, I think some of the problem might be where the 990 noise generator falls in the circuit. On my unit it appears the test generator is after the crossover and bass management so I get noise level up to the highest frequency my sub (an LFM-1) can produce. The LFM is set with its crossover to bypass but when I engage it I can hear it working. The 990 crossover was set at 80Hz. My experience with other preamps has been when the noise generator was before the bass manager I would not be able to hear any difference switching the sub crossover in and out with the sub crossover set to its highest frequency.

There has been no information regarding this Bypass issue for a number of days. What has been resolved? I do not dare buy a 990 unless I know the Bypass mode is working because I listen to a lot of 2 channel stereo.

Still no update. Last I heard, Scott told me they are working on it. I have faith that they will fix it eventually...

Hello Otto and sailorman,

I am working with the software team on this issue. Thanks for your patience and understanding while we take the time to get it right!

Best!

Scott

Scott,

While you and the software Outlaws are working on this BYPASS problem, have you ever discussed whether the BYPASS option could also be made apply for the 7.1 analog input too? The 990's full digital processing and bass management are great and will always be needed for digital sources like cable TV boxes, but it would be nice to be able to bypass it for a high end 5.1/7.1 analog source.

Scott would have a better answer than I, but I do recall this being discussed a year or so ago. I'm not sure of the reasons why it wasn't able to be implemented at that time, but Outlaw was unable to do so then. If they were able to work out a way between then and now, of course, it would be a nice touch (even if I doubt that I'd use it ).

I check this thread everyday hoping the fix is near.

You are not alone.

my issue is that I have to go to the menu and change the mains to large every time I want to listen to full range 2 channel in bypass. I would imagine if you are running Klipschorn's and LaScala's you have the speakers set at large all of the time. You must have lots of space for those speakers. I know they are the size of a washing machine because I had a pair of LaScala's way back when and I constantly fried the tweeter. Lucky for me there was a speaker repair shop close to me and he would change out the diaphragm for $60 every time. I always wanted a pair of Klipschorn's, they must sound incredible with the Macintosh amps.

Any word on a timeline yet?
