8. Digital Radio: DAB/DAB+
Digital Audio Broadcasting (DAB or DAB+) is the digital
successor to analogue VHF broadcasting. Digital
transmission differs from the familiar analogue VHF radio in
the following ways.
Several stations are broadcast on one channel, the so-called
multiplex (ENSEMBLE) (= program packages).
The stations that fall within a given MULTIPLEX are called
SERVICES (= stations and/or data services).
In Germany, for example, the MULTIPLEXES are available
regionally from public broadcasters; moreover, there are
currently two MULTIPLEXES that can be received
throughout Germany: DR DEUTSCHLAND and ANTENNE
DE. The stations do not output disagreeable noises known
from VHF; a station is either heard with a consistent quality
or breaks up when error correction is no longer able to
reconstruct the signal, accompanied by short, so-called
"burbling" noises.
Starting to play the DAB/DAB+ radio
Use the SRC or DAB+ button to select the DAB1, DAB2 or
DAB3 source.
If necessary, run a scan using the DAB SERVICE SCAN menu
option (DAB SERVICE SUCHE) to find stations available in
your location (see "SETTINGS").
Tip: some of the memory sources/levels are inactive
depending on the setting; only the DAB1 memory level is
active by default. See "SETTINGS".
Tip: there are 5 memory slots available for each memory
level.
