DAB500
AN OVERVIEW OF DIGITAL AUDIO
BROADCASTING (DAB)
This section gives a brief overview of digital radio, or DAB as it is also known, along with some useful addresses if you require further information.
The Cambridge Audio DAB500 lets you receive and listen to the abundance of digital radio broadcasts available. DAB uses digital signals rather than traditional analogue transmissions, providing clear, high quality reception.
Digital radio is broadcast as groups of data called multiplexes. Each multiplex contains a number of stations, transmitted at a set frequency, which the DAB500 decodes. The DAB500 can receive multiplexes broadcast on Band III DAB frequencies. The number of multiplexes and radio stations you receive will vary depending on your location. With DAB, radio stations have labels for identification. Instead of needing to know a particular frequency to listen to your favourite broadcast you can simply select the station name.
DAB also enables broadcasters to transmit additional data with the audio, which takes in other audio channels, text and in the future, perhaps computer data and images. Additional data, such as text containing programme or multiplex information, is shown on the DAB500’s display.
