Turning Loudness On or
Off
Loudness introduces a special low and high
frequency emphasis at the lower volume
settings. This compensates for the ear's
decreased sensitivity to bass and treble sound
at these low listening levels.
Note: When an equalizer or digital sound
processor is connected, this function is
inoperative.
