Volume/tone settings, function

A distinction must be made between COMAND audio and service sources:

 Audio sources include e.g.:
 Radio
 CD player

 Service sources include:
 Traffic radio announcement
 Telephone (optional)
 Voice output for navigation

Volume setting
Changing the volume of an audio source has an identical effect on all other audio sources.

The volume is also jointly regulated within the service sources in the same manner. The volume of voice output for navigation can be changed during voice output.

-----------------------------------------------------------------------------------------

In this case, a distance - which can be set in the "Settings" menu - between the volume of the audio signal and voice output is automatically adhered to. This ensures that the voice output can be heard well even with loud audio output.

Tone setting
COMAND allows various tone settings (e.g. trebble/base, balance, fader) for every audio source. The tone setting selected for the radio simultaneously applies to the traffic information radio channel message. Settings which are selected for voice output during navigation also influence the language control system. Firmly stored tone settings can additionally be called up, e.g.:

 pop

 classic

 voice

-----------------------------------------------------------------------------------------

When the tonal focal point is changed (balance, fader), the relationship between the volume of the other loudspeakers also changes.

The signal processing required for the volume and tone settings is undertaken by the audio components integrated in the COMAND operating, display and control module (A40/3).
