If you're asking how to change the reference level offset (RLO), it's in the Denon menus, as someone else pointed out.
But if you're asking what number to choose, it's a matter of personal preference. The RLO controls how much increase in subwoofer and surround speaker volume you want at volume levels below reference (which is set at 0 dB after calibration). If RLO = 0, you get the maximum increase in both of these things. That is supposed to work with the way BluRay movies are mastered for the home (I say "supposed to," because this isn't always the case).
If you set RLO = -15 dB, then you are getting the minimum level of added subwoofer and surround volumes at lower volume levels. Obviously, the other setting given you more moderate levels of adjustment. With Dynamic EQ off, there is no additional subwoofer or surround volume added at lower volume levels.
Basically, using Dynamic RQ and choosing the reference level you want is totally up to your preference. You'll find a range of opinions here on this. I generally have it set to RLO = 0 for movies unless the surrounds seem too loud; I leave it at RLO = -10 for most cable TV (shows from the BBC seem better with DynEQ off, or else the surround channels are ridiculously loud), and I turn off DynEQ for all music.
