I either turn it on manually or temporarily bump up the volume until it's on.
Didn't know there actually was a way to use the sub in Pure Direct mode on Denons.
You still haven't told us what bookshelves you're using; they may require a higher crossover.
Also with Pure Direct you won't get the benefits of Audyssey room correction so the sub will likely be more affected by room modes and the like.
I am using the Focal Chorus 807V bookshelf speakers. Below are the specs of the 807V:
Type: 2-way bass reflex bookshelf loudspeaker
7" Polyglass mid-bass
1" TNV inverted dome tweeter
Frequency response (±3dB): 50Hz-28kHz
Sensitivity (2.83V/1m): 92dB
Nominal impedance: 8 ohms
Power handling: 160/110W
Dimensions (HWD): 17-5/8" x 9-1/3" x 13-1/8"
What would be the best Crossover for these speakers? Right now, I have the Crossover at 80Hz from the Denon receiver.
Thanks for any advice!
