Oh yeah, sub's on and working when listening to music in "stereo", "bypass" and "upsample" modes. But when I use "Test"-"OK"-"OK" to trim the sub with the remote, I appear to get no change until -- BOOM -- at -12 dB or whatever.

Using the same song and method in "5-channel stereo", the sub trim via remote seems to work OK -- probably because the 990 has not applied any 2-ch sub offset in 5-ch mode, and the 2-ch offset is playing into this somehow.

I've never tried this during the channel calibration in the OSD, but I can try tonight. So far, I've only tried to trim the sub, via remote, while listening to a 2-channel mode.
