An earlier posting made me bring up the pdf for my Denon 3806. My eyeballs happened to catch this item even though it's unrelated to what I was looking for.
----------------------------
LFE (Low Frequency Effect):
This sets the level of the LFE (Low Frequency Effect) sounds
included in the source when playing program sources recorded
in Dolby Digital, DTS, DVD-audio or Super Audio CD.
Program source and adjustment range:
–10 dB to 0 dB
When DTS encoded movie software is played, it is
recommended that the LFE LEVEL be set to 0 dB for
correct DTS playback.
When DTS encoded music software is played, it is
recommended that the LFE LEVEL be set to –10 dB for
correct DTS playback.
---------------------------

This appears to be separate from the sub channel setting when you set the db levels for all your speakers. I never spotted it before, so I'm not sure.

Will this automatically adjust when Dolby changes to DTS or does it have to be manually changed.

If manual, is anybody doing this? I can't imagine it being manual but it is not clear.

Am I misunderstanding this? 10db is a lot of SPL in the difference.....
