Guide to Digital Radio
Your DRX-601E/ES enables you to receive and listen to the new DAB radio programmes. Digital Audio Broadcast (DAB) is a new form of radio
broadcasting using digital signals rather than traditional analogue signals. DAB provides near CD-quality audio with virtually interference-free
reception. DAB also enables broadcasters to transmit additional data along with the audio including other audio channels, text and in the future,
perhaps computer data and images.
Digital radio is broadcast as groups of data called ensembles or multiplexes. Each multiplex can contain a number of services (stations) and each
service 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 your DRX-601EX for decoding. Your DRX-601EX
enables you to receive multiplexes broadcast in frequency
band III (174-240 MHz) and store the services in each
multiplex for you to access. The number of multiplexes you
receive will vary depending on your location. Band III is
divided into 41 channels labelled 5A to 13F.
Each channel
can contain one multiplex. Channels allocated to the UK are in
the range 11B to 12D.
Multiplexes and services have labels (names) which are used
to identify them. Instead of needing to know a particular
frequency to listen to your favourite broadcast you can simply
select the service name. Secondary services and additional
data such as text containing programme or multiplex
information are also easily accessed using your DRX-601EX.
