6、ht and dimensions are approximate.About DABWith this unit you can receive and listen to Digital AudioBroadcast (DAB) programmes. DAB uses digital, not analoguesignals, resulting in near CD-quality audio with virtuallyinterference-free reception. Along with superior quality audio,DAB can also deliver

7、 additional audio channels and text. In thefuture, computer data and images are also possible.Digital radio is broadcast as groups of data called ensembles ormultiplexes. Each multiplex can contain a number of stations(services) and each station contains a primary service and cancontain secondary se

8、rvices as illustrated in the following diagram.Each multiplex is transmitted in a set frequency range andreceived by this unit for decoding. You can receive multiplexesbroadcast in the 174240 MHz frequency band and store theservices in each multiplex for you to access. The number ofmultiplexes you r

9、eceive depend on your location. Channels usedin the UK are in the range 10A to 12D.Multiplexes and stations have labels (names) that are used toidentify them. Instead of needing to know the particular frequencyof your favourite broadcast, you can simply select the stationname. Secondary services and
