Changing the sound and
beep tone
Boosting the bass sound — D.bass
You can enjoy clear and powerful bass sound.
The D-bass function boosts the low frequency
signal with a sharper curve than conventional
bass boost.
You can hear the bass line more clearly even if
the vocal sound is the same volume. You can
emphasize and adjust the bass sound easily
with the D-bass control. This effect is similar to
the one you get when you use an optional
subwoofer system.
Moreover, the Digital D-bass* function creates
even sharper and more powerful bass sound
than Analog D-bass.
* Digital D-bass is available during CD playback.
Adjusting the bass curve
Turn the D-BASS dial to adjust the bass
level (1, 2 or 3).
“D-BASS” appears in the display.
During CD playback, “DIGITAL D-BASS”
appears in the display.
To cancel, turn the dial to the OFF position.
Note
The bass sound becomes distorted, adjust the D-
bass dial or volume control.
Attenuating the beep tone
Press (6) while pressing (SOUND).
To obtain the beep tone again, press these
buttons again.
Note
If you connect an optional power amplifier and do
not use the built-in amplifier, the beep tone will
be disabled.
