Optimal sound reproductionThe audio system is calibrated for optimal
sound reproduction through the use of digital
signal processing. This calibration takes into
account the speakers, amplifier, cabin acous-
tics, the seating position of the listener, etc., for
each combination of vehicle and audio system.
There is also dynamic calibration that takes
into account the setting of the volume control,
radio reception, and the vehicle's speed. The
sound settings described in this manual, such
as
BASS
,TREBLE
, and
EQUALIZER
are only
intended to enable the user to adapt sound
reproduction to his/her personal preferences.
