Volume/Tone Settings

A differentiation is necessary between the COMAND audio sources and service sources:
- Audio sources are
- Radio
- Cassette player
- CD changer (optional)

- Service sources are:
- Traffic announcement (except USA)
- Telephone
- Voice prompt for navigation
- Voice control system (optional)

Volume setting
Changing the volume of one audio source has an equivalent effect on all other audio sources. In the same manner the volume for the service sources is adjusted in common.

The volume of the voice prompt for navigation can be changed during voice prompt output. A minimum difference of at least 12.5 dB is maintained automatically between the volume of the audio signal and the voice prompt. This ensures that voice prompt can always be heard well.

Tone settings
The COMAND system allows various tone settings (e.g. bass/treble, balance, fader, ...) for each audio source. The tone settings selected for the radio apply simultaneously for the traffic station announcements. Settings selected for the navigation voice prompt also effect the voice control system.

Moreover, permanently stored tone settings can be called for optimization of the sounds from the audio sources, e.g.:
- Pop
- Classic
- Voice
- Spatial simulation,...

When the tone focus (balance, fader) is changed, the volume ratio for the individual speakers changes.

The signal processing required for the volume and tone settings is accomplished either by the audio components integrated into the COMAND operating, display and control module (A40/3) or by the sound amplifier (A2/13) (with code 810).
