About DAB (Digital Audio Broadcasting)

Since the DAB system is broadcasted in digital format, DAB system can supply crystal-clear audio and stable reception even in mobile objects. DAB is a new generation radio which can provide data service and supplementary multi-media services.

Each component contains inherent programmes; news, music, sports, and many more.
