Guide to Digital Radio
This section provides a brief guide to digital radio (DAB), explains how the features of your DRX-601E/ES provide access to it and provides
some useful addresses for finding out more.
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-601E/ES for decoding. Your DRX-601E/ES 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-601E/ES.
