Owner's manual says "Night mode feature normalizes the overall volume loudness to avoid sudden changes in loudness. This feature is available with DTS:X and Dolby content via HDMI, HDMI ARC, Optical and Coaxial Inputs.
DRC 100 - 100% of volume normalization, perfect for night time listening
DRC 50 - 50% of volume normalization
DRC OFF - Volume Normalization Off"
Personally, I would think a typical NIGHT mode would remove the bass in order to not wake up people in the house with rumbling. But that actually isn't what it explains. It's explanation is more like a "Loud Commercial" feature where sudden changes in loudness are evened out. Or perhaps explosions might be not as loud, once they are "evened out", etc.
It has not really worked for me - I have ignored it for about a month, and then pressing it last night when listening to DOLBY input via HDMI ARC, seemed to "shutoff my front soundbar". And pressing SUR ON was the only solution.
