They certainly think they do... That's not to say that there can't be a bug in the firmware as there was one in the recent past.

The G68's calibration routines should set you up with a 10dB boost on the *LFE* channel*. Using the G68 calibration tones, are you setting *every* channel to the same level on your SPL meter?

I now have a working sub again and plan to do quite lots of A and V calibration over the Easter w/end. Hopefully I'll be able to report back then.


* Any non-LFE bass transferred from the other channels should *not* have the boost.
