Digital Audio Broadcast
(DAB)
DAB Basic Information
DAB is short for ‘Digital Audio Broadcast’ and
is a new form of radio broadcasting which
utilizes digital technology. DAB is capable of
providing near CD quality audio with virtually
interference free reception.
DAB operates in frequency band III (174
– 240MHz). Band III is divided into 41 chan-
nels labeled 5A to 13F.
DAB channels are categorized into ensembles,
which are also known as multiplexes. Each
multiplex provides a number of stations and
each service contains a primary service that
can contain secondary services. DAB technol-
ogy allows broadcasters to transmit additional
data along with the audio, which can include
other audio channels, text and in the future,
even images and computer data.
NOTE: When the DAB tuner is used for the
first time the FL display will ask whether you
want to auto-tune to find the available ser-
vice in your area. For most applications
auto-tune should only need to be carried out
once. Select <YES> to confirm the selection.
The tuner will then search automatically for
available stations on the DAB network. The
number of stations received will depend on
the location of your aerial and the available
multiplexes in your area. For optimal recep-
tion we recommend using a dedicated out-
door aerial.
