About DAB
With this unit you can receive and listen to Digital Audio
Broadcast (DAB) programmes. DAB uses digital, not analogue
signals, resulting in near CD-quality audio with virtually
interference-free reception. Along with superior quality audio,
DAB can also deliver additional audio channels and text. In the
future, computer data and images are also possible.
Digital radio is broadcast as groups of data called ensembles or
multiplexes. Each multiplex can contain a number of stations
(services) and each station contains a primary service and can
contain secondary services as illustrated in the following diagram.
Each multiplex is transmitted in a set frequency range and
received by this unit for decoding. You can receive multiplexes
broadcast in the 174­240 MHz frequency band and store the
services in each multiplex for you to access. The number of
multiplexes you receive depend on your location. Channels used
in the UK are in the range 10A to 12D.
Multiplexes and stations have labels (names) that are used to
identify them. Instead of needing to know the particular frequency
of your favourite broadcast, you can simply select the station
name. Secondary services and additional data such as text or
multiplex info are also available.
