Turning Loudness On/Off

Loudness introduces a special low- and high-frequency emphasis at
low listening levels. This compensates for the ear's decreased
sensitivity to bass and treble sound.
Press and hold the Rotary encoder (MODE/LOUD)
for at least 2 seconds to activate or deactivate the
loudness mode.
The display shows "LOUD ON" when the loudness mode is
activated.
