Digital Audio Broadcast
(DAB)
DAB is short for ‘Digital Audio Broadcast’ and
is a new form of radio broadcasting which
utilizes digital technology. DAB is capable or
providing near CD quality audio with virtu-
ally interference free reception.
DAB operates in frequency band III (174-
240MHz) and L-band (1452-1490MHz).
Band III is divided into 41 channels labeled
5A to 13F and L-band is divided into 23
(24 for Canadian L-band) channels labeled
LA to LW.
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.
Basic Operations of DAB
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 service
in your area. For most applications auto-tune
should only need to be carried out once. Se-
lect <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 reception we recom-
mend using a dedicated outdoor aerial.
BAND, DAB buttons
The RT-06 receives AM, FM and DAB signals.
DAB mode is selected by pressing the BAND
key on the front panel. Direct access to DAB
mode can be selected using the DAB button
on the remote control.
UP, DOWN Buttons
The UP and DOWN keys available on the
front panel and remote control can be used
to change between stations and also for
selecting options in the set-up menu (see
SETUP MENU).
ENTER Button
Press the ENTER button on the front panel to
confirm a selected parameter.
DISPLAY Button
The RT-06 shows the service identification
in the upper portion of the FL display. This
information is received by the network and
allows the RT-06 to display six available
modes. Press the <DISPLAY> button to toggle
through the different modes which are shown
on the lower portion of the FL display. The six
modes are as follows:
• Program type: Displays genre or other
program information.
• Ensemble name: Multiplex identifica-
tion is displayed.
• Frequency: Indicates the frequency that
the selected multiplex is transmitted on.
• Bit rate: The rate at which bits (informa-
tion) are transmitted. This is expressed
in thousands of bits per second (Kbps),
which effectively shows the quality of the
broadcast. The higher the bit rate is the
better the sound quality is.
• Dynamic label segment: This is the
text that scrolls across the FL display and
gives information on the play list and cur-
rent program content. This feature is subject
to the service provider and station.
• Signal strength: Indicates the input
signal level to the DAB module in block
format.
MEMORY Button
The RT-06 can store up to 99 DAB preset
stations. When you want to save a selected
station, press the memory button on the front
panel, then one of the numerical buttons of
the front panel that you wish to save the sta-
tion to. FM and DAB memorized stations are
separate meaning that a station can be saved
to ‘1’ on DAB and another station with the
same number for FM.
NUMERIC Button
The numerical buttons can be used to store to
a PRESET station or recall a PRESET.
TUNE/PRESET Button
The RT-06 has two operating modes:
• DAB Manual Mode:
When the tuner is selected to this mode,
you can scroll through all the available
stations using the up and down keys.
• DAB Preset Mode:
Use the preset button to enable you to use
the up and down keys to scroll thourgh
your saved stations. Preset is displayed in
the FL display once this mode has been
selected.
