DAB radio stands for Digital Audio Broadcasting and is a digital radio standard for broadcasting digital audio radio services in many countries around the world. It is a digitally transmitted sound that combines multiple audio streams onto a relatively narrow band centered on a single broadcast frequency called a DAB ensemble. DAB offers space for more radio stations at a better audio quality than FM or AM. DAB is less susceptible to interference and gives listeners more choice of radio stations. The range of DAB is much wider, and because it is digitally transmitted, the quality is also better. Because it does not use radio waves, there is no noise. DAB radios can receive all radio stations, and you are no longer dependent on good reception. Many modern radio stations are also switching to DAB. DAB radios can switch channels easily, and all available stations are in a handy alphabetical list. Most DAB radios have an internal memory that allows you to save some of your favorite radio stations. DAB+ is a more efficient method of broadcasting music and is based on the AAC codec popularized by Apples iPod. DAB+ is more efficient than the old standard that uses MP2 and means a higher quality signal is possible than before. DAB+ is the standard used for digital radio in Australia and is not compatible with the older DAB format. To use DAB technology, you need a suitable radio, and all JBL DAB+ radio speakers have this technology.
