Late Night mode is to compress the dynamic range of the sound volume - meaning the Amp will auto bring down the volume when the scene is loud, and auto bring up the volume when the scene is quiet - no good for watching action film because a scene with explosion will sound in similar volume with a scene with people talking - totally losing the experience of watching a film.
