AUDIO
ADDITIONAL FEATURES (LEVEL 1)
Speed Dependent Volume (SDV)
The SDV system adjusts the radio volume depending on the vehicle’s speed. As the
vehicle’s speed increases, the volume of the radio also increases to compensate for
the driving noise.
Note This feature will never completely compensate for the driving noise. There are
other variable factors such as road surface, wind noise, windows open, engine speed
etc., that may alter the interior noise for any given road speed.
For this reason, there are different levels of compensation available to allow you to nd
one that suits your average driving conditions best.
You can select the compensation rates between ‘OFF’ and ‘CUR 6 (Curve)’ (maximum
compensation) in the Options Menu.
To alter the SDV setting:
1.
Enter the Options menu by pressing the Volume Control Dial
S
when the radio is
switched on.
The menu item ‘AUDIO’
is highlighted.
2. Turn the Volume Control Dial
S
clockwise to highlight ‘AUD SETUP’.
3. Press the Volume Control Dial
S
to access the audio setup menu.
4. Turn the Volume Control Dial
S
clockwise to highlight ‘SD VOLUME’.
5. Press the Volume Control Dial
S
to access the SDV setting.
6. Turn the Volume Control Dial
S
clockwise or anti-clockwise to alter the SDV
setting.
7.
Press the Volume Control Dial
S
to exit and store the setting.
8. To exit the menu, select the ‘BACK’ option or wait 8 seconds.
Dynamic Distortion Limiter (DDL)
Your radio is equipped with a system that limits the amount of amplier distortion you
can hear. When this feature is turned on, it continuously monitors the quality of the
signal to the speakers. When the signal distortion exceeds preset limits, the radio will
automatically limit or reduce the volume until the distortion is minimised. The system
is dynamic so that it is always monitoring the sound in order to deliver the selected
volume level without distortion. Under some circumstances distortion may be heard for
a very short time until the system has taken the necessary steps to limit it.
Note The main source of distortion in music is the low frequency bass caused by drums
or large instruments. Tracks that feature very strong bass may trigger the distortion
limiting system which will then reduce the volume to minimise the distortion. Increasing
the Bass control may also result in a reduced volume level due to the emphasised
bass. If desired, the DDL can be turned off in these circumstances so that the radio will
deliver a higher volume level. Naturally, distortion will also be increased. You can select
the distortion limiter rates between ‘OFF’ and ‘CUR 3 (Curve)’ (maximum limiting) in
the Options Menu.
