About DAB With this unit you can receive and listen to Digital Audio Broadcast (DAB) programmes. DAB uses digital
6、, 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 c
7、alled 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 deco
8、ding. 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) th
9、at 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. DAB SIGNAL MULTIPLEX PRIMARY SERVICES SECONDARY SERVICES Pa
