Bush CCR231DAB - What is DAB?

What
is
DAB?
DAB radio will change the
way
that
people
listen to radio
over
the next
few
years.
You will
probably
not be aware that
digital radio will become
mandatory in the
future
as the terrestrial radio frequencies which
you
currently listen
to
will be
re allocated for
other uses
such as emergency
services.
This means
that
today
you
are
one
of the
pioneers
using this
technology,
however in a short
space
of time everybody will benefit from
clear
digital
radio.
Digital radio offers
an
abundance of new digital only stations and improved
sound
quality. There
are
no
frequencies to
remember
so
the CCR231DAB
can
be
tuned by searching
through
station
names.
The
audio
quality
of
DAB is near that
of a CD
with virtually
no
interference and
no retuning. DAB
is
also enhanced with DLS
(Digital
Label
Segment), this
is data transmitted
by
the
station
which
may
include information about the station,
program
or
song
(see
page
9).
The
BBC
was the
pioneer
of
digital
radio, beginning transmissions in
September 1995.
Digital
One, the national commercial radio
multiplex
operator, began broadcasting in November 1999.
There
has
been
a
growth
in the
number
of
digital
radio
stations
throughout the
UK and
both the BBC
and
Digital
One
are committed
to extending their coverage. Digital One
currently covers 80% of the UK
population,
soon
to increase to 85%, and
the BBC covers 65%
with the
aim
of increasing coverage to 90%
Your
CCR23'1DAB
will receive
DAB
programs
broadcast on Band
3
digital
radio
(174-240MHz).
There
are a
total of 41
channels
within this
range
numbered
5A
to
13F, the
number
of
channels
you
can receive
will
be
dependant on
your
location
and
signal strength,
The
UK has been allocated
seven multiplexes by the
Radio
Authority
-
in the spectrum
217.5-230.0
MHz.
which
are
numbered
118
to
12D.
A multiplex is a broadcaster such as BBC
National DAB or
Digital
One
who
will
provide
a
host
of different stations
within their multiplex. lf we
consider the
BBC as
an
example, the following diagram shows how
the
BBC
multiplex may work.
Below
the
main
multiplex
provider (in
this case
'BBC
National
DAB')
will
be
a
number
of
primary
stations.
These
are
labelled with the
station
name
(e.g
Radio 2)
rather
than the frequency. This allows
you
to
tune
the CCR231DAB
by
station name, which is easier
than
trying
to
recall
frequencies.
Sometimes a secondary service
station may be
provided
by
the
broadcaster,
for instance this is sometimes used when an alternative
commentary is
provided
on a
sporting match
or event.
These secondary
service
stations
are
not
permanent
and
may
not
always be used
for
broadcast.
When a secondary station is available below
the
primary
station,
a
'>'
symbol will be displayed after the
primary
station
name. A
secondary
station
can
be
recognise by the
'<'
symbol before the secondary station
name .

you
