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.
