Volume/Tone Settings

A differentiation is necessary between the COMAND audio sources and service sources:
- Audio sources are:
- Radio
- CD player

- Service sources are:
- Traffic announcement
- Telephone and voice control system (optional)
- Voice output for navigation

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 output for navigation can be changed during voice output output. Here, an adjustable interval is maintained between the volume of the audio signal and the voice output automatically (can be adjusted in "Settings" menu). This ensures that voice output can be heard well even when the audio system is loud.

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 output also affect the voice control system. Moreover, permanently stored tone settings can be called, e.g.:

- Pop
- Classic
- Voice

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

The preparation of the signals required for the volume and tone settings is accomplished by the audio components integrated into the COMAND operating, display and control module (A40/3). When the vehicle is also equipped with sound system (with code 810), the sound system amplifier (N40/3) provides for final amplification of the audio signals.
