7.2 CD compression
CD compression reduces the dynamic
range of the CD by reducing the
amplitude of high level signals and
increasing the amplitude of low level
signals.
Compression is useful in car audio
systems when the dynamic range
of CDs exceed that of the listening
environment.
A typical car audio system will play a
maximum level of about 105dB SPL
(Sound Pressure Level). Road and
engine noise at 100km/h can be around
70dB SPL, leaving an acoustic dynamic
range in-vehicle of 35dB SPL. On a CD
with a dynamic range of 80dB, the soft
passages of the disc will not be audible
above the acoustic road and engine
noise.
By compressing the CD signal and more
closely matching the dynamic range of
the vehicle, quiet passages can once
again be heard.
Press the OK button (12) to select or
deselect CD Compression.
7.3 Audio off with driver door
open
This feature ensures the currently playing
media continues to play when you
remove the key from the ignition.
The audio unit will then switch off
automatically when the driver’s door is
opened.
Press the OK button (12) to select or
deselect audio off with driver door open.
7.4 Speed dependent volume
This feature allows automatic adjustment
of the volume with vehicle speed. The
amount of compensation is proportional
to the vehicle speed which translates to
vehicle road noise.
Eight levels of adjustment are available.
Turn the ICC Control Dial (2) clockwise
to increase the level of compensation
applied.
Turn the ICC Control Dial (2)
counterclockwise to decrease the
amount of compensation applied.
