DAB stands for digital audio broadcasting. It is a new form of radio that is
broadcast digitally. Unlike regular analogue broadcasting, digital radio
deteriorates less, and is thus able to provide quality sound close to that of a CD.
Band
There are two types of DAB bands, “BAND
Ⅲ
” (Receivable on this unit)
and “L BAND” (Not broadcast in the UK, and not receivable on this unit).
Frequencies
There are 41 frequencies on BAND
Ⅲ
. Among those frequencies, 7 are
used in the UK (current as of March, 2004).
Ensemble, station and service
The number of stations that make up one frequency differ between DAB
and analogue radio. Analogue stations all broadcast on different
frequencies, even if it is the same company doing the broadcasting. With
DAB however, it is possible to broadcast a number of stations on the
same frequency.
In DAB terminology, a group of stations on the same frequency is called
an ensemble.
As shown in the diagram, an ensemble consists of a group of stations
which have primary services, they can also have secondary services.
This means, for example, that commentary on sports events from
different areas can all be broadcast at once.
Depending on the region there is a difference between broadcast
frequency and stations broadcast along the same frequency. For this
reason, a memory of receivable stations should first be created and then
selected from those memorized stations as the reception method.
DAB Auto Scan
This function searches for currently receivable stations and inputs them
into unit memory.
When DAB is selected for the first time, this function starts automatically.
Note
Note
Even if the station is stored into memory, some stations may not
broadcast depending on the time of day etc. If this occurs, “NO
SERVICE” is displayed.
Station Memory Updating
When there is a station name change, or a new station begins
broadcasting, the unit memory is automatically updated when:
• The previous station name is displayed by selecting “STATION TUNE”.
• One of the stations already broadcasting on the same frequency with
the new station is displayed by selecting “STATION TUNE”.
Note
Note
• Deleting stations that are no longer broadcasting is not automatic. If
you want to delete a station, perform Auto scan again and the new
memory is created.
• When a new frequency begins broadcasting, stations on that new
frequency are not automatically added to memory. Perform Auto scan
to add them to memory. Also, you may need to change the Auto scan
range if the new frequency is outside the factory set Auto scan range
(
Page 8).
STATION TUNE
You can select stations from the memory created as shown above in
alphanumeric order. You can also easily select your favorite stations by
using presets (
