DAB
The digital radio system DAB (digital
audio broadcasting) is a universal
broadcast system.
DAB stations are indicated by the
programme name instead of the
broadcasting frequency.
General information
■ With DAB, several radio
programmes (services) can be
broadcast on a single frequency.
■ Besides high-quality digital audio
services, DAB is also able to
transmit programme-associated
data and a multitude of other data
services including travel and traffic
information.
■ As long as a given DAB receiver
can pick up the signal sent out by a
broadcasting station (even if the
signal is very weak), sound
reproduction is ensured.
■ There is no fading (weakening of
the sound) that is typical of AM or
FM reception; the DAB signal is
reproduced at a constant volume.
■ If the DAB signal is too vague to be
interpreted by the receiver,
reception is interrupted completely.
This incident can be avoided by
activating Auto ensemble linking
and/or Auto linking DAB-FM. See
“Configuring DAB” below.
■ Interference caused by stations on
nearby frequencies (typical of AM
and FM reception) does not occur
in connection with DAB.
■ If the DAB signal is reflected by
natural obstacles or buildings, the
reception quality of DAB is
improved, whereas AM or FM
reception is considerably worsened
in such cases.
■ The radio is also capable of
reveicing DAB+ and DMB-Audio.
Configuring DAB
1. Press the CONFIG button.
2. Select Radio and then DAB.
The following options are available for
selection in the configuration menu:
■ Auto ensemble linking: with this
function activated, the device
switches over to another service of
the active DAB ensemble (if
available) when the DAB signal is
too vague to be interpreted by the
receiver.
■ Auto linking DAB-FM: with this
function activated, the device
switches over to a corresponding
FM station of the active DAB
service (if available) when the DAB
signal is too vague to be interpreted
by the receiver.
■ Dynamic audio adaptation: with this
function activated, the dynamic
range of the DAB signal is reduced.
That means the level of the loud
sounds is reduced, but not the level
of the quiet sounds. Therefore the
volume of the Infotainment system
