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 (CDE-9846 only)
or press and hold MODE (CDE-9842 only) for at least
2 seconds to activate or deactivate the loudness mode.
The display shows "LD" when the loudness mode is activated.
