LFE is a specific coding done during production which is why you see the "play low range and LFE signals of all speakers set to small" or 'LFE + main "play low range and LFE signals of all channels", it's just that the specific LFE signal is now getting played through the front main speakers as well as the sub with the LFE + Main setting.


The low range should be what ever is below your crossover setting in the receiver.

2 channel stereo for Denon, I do believe, they don't use the sub except in LFE + Main mode, but in direct mode the sub is always on regardless of any xover settings..
