About DAB Radio
DAB stands for Digital Audio Broadcasting, and is a technology used for broadcasting radio stations which operates over a wide variety of countries throughout the world. The technology started development in 1980 as a European research project, but it wasn't until 1995 that the first DAB channel was launched by the Norwegian Broadcasting Corporation - the station was called NRK Klassisk, and it first went on air on June 1st. Most of the large electronic companies design, produce and sell a version of the DAB radio. The designs come in many shapes and sizes, with some considered more aesthetically pleasing than others. DAB radios can be portable, either taken on the move with a set of in-ear personal headphones, or for wider use in a communal area, for example at a campsite. More often than not, DAB radios will be set to one place in a house, with a need for a power supply. Sometimes, the radios will come with other functions, such as an AUX input to play back content on external media devices, bluetooth connectivity options, or dock spaces for personal music players. DAB radios can still pick up FM and AM stations. In February 2007, an updated version of the system was released to the general public, which is referred to as DAB+. DAB+ is roughly twice as effective at transmitting digital signals as standard DAB, because of additional audio codecs. DAB+ delivers high quality audio whilst keeping the wave-length as low as 64 kilobytes per second. Some modern DAB radios will have DAB+, as denoted on the product's packaging.
