Lemme guess... is it a setting related to matching/complementing subwoofer or surround speaker levels?
Or this...
"The loudness control is simply intended to significantly boost low and high frequencies when listening at low levels so that the ear perceives an overall flatter sound pressure level." Like EQ?
Let's say it's for the soundbar/subwoofer/rear speakers. The default level is at 0 or after a reset of the soundbar the levels revert to factory settings of 0
Normally, if you want to hear louder sound you just adjust the volume positively upwards.
What I want to know is when you have 'minus' setting it means what? My soundbar can adjust the sound volume from minus(-) to plus(+) levels for the mentioned devices
Is setting at -4 the same loudness as +4 setting? In avsforums I can see people set to -4, -5 and -6 levels. Cannot be minus settings means lower loudness settings, right?
