You should keep the lowpass freq in all profiles as high as you can (probably 120Hz), so you are 100% sure the subwoofer does not mess up your receiver's idea of bass management. Phase should be identical in all profiles as well. I see no reason to change that if you go from music to movie or back. The room and speaker placements both stay the same so when it's set up correctly, leave it just there About the gain settings: I would say.. calibrate your setup with the sub in Music mode. If there exists an EQ-off/"leave the input signal alone" mode on the sub, choose that one. For the night mode you could lower the gain a bit and for movies raise it up a bit if you prefer so. My thoughts were that the Movie mode boosts sounds in the 50-60Hz range and Music mode boosts the lower <35 Hz end. But maybe I am confused with the RT series controller.. hmmzzz... That's a nice one to check in the manual. Anyway, I am not the kind of person who would switch his sub every time I go from a movie source to music... Personally I'd set it up right once so it sounds right with both movies and music. I do sometimes adjust the volume a little with that big side mounted volume control, but thats all.. no profiles or so. Hope this helps a bit. Now I gotta catch some sleep.. It's been past 2:30 AM here in NL haha

That is correct. The sub is a dumb device and can only switch itself on from standby mode. It won't auto-choose it's own EQ profile: it's the receiver which decides to output a LFE signal to the sub, depending on the input signal channels and/or the surround mode you put it in. If you select a 2 channel source and the receiver is in stereo or "pure direct" mode (or something similar), your subwoofer will not receive a signal. There is a possibility to get your sub pumping in stereo mode: set your fronts to small in the receiver settings. Your first question was about the crossover setting, so I assume your fronts are already set to small. The crossover has no job if the fronts are set to Large, cause there is nothing to cross (Large=fullrange) So set and keep them to Small, crossover to 60 or 80 Hz, depending to what sounds best and.. enjoy

A small addition: If you use the LFE connector, the sub's LPF is automatically bypassed. So if you forget to turn it to 120Hz there's nothing to worry about as the low pass filter is disabled.
