Sound
You can adjust the sound settings (bass,
middle and treble) separately for each
source (radio, CD, CD changer, USB, AUX,
and telephone/navigation). The volume
distribution settings (balance and fader)
and X-BASS apply to all the audio sources
except for telephone/navigation. You can
adjust the volume distribution settings sep-
arately for telephone/navigation.
Note:
The settings of the sound for telephone/
navigation can only be made during a
telephone call/voice output.
This device features a digital 3-band equal-
izer. This equalizer allows for selecting one
frequency each for bass, treble and middle
and to adjust the level for the selected fre-
quency between -7 and +7. In addition, you
can adjust the quality factor for bass and
middle.
Note
The quality factor determines the fi lter
quality of the equalizer, i.e. the edge
steepness and fi lter bandwidth, de-
pendent upon the characteristic fre-
quency.
A low quality factor means a low edge
steepness and a high fi lter bandwidth;
a high quality factor means a high edge
steepness and a low fi lter bandwidth.
