Digital Audio Broadcast (DAB)

 

DAB digital radio reception offers a listening experience of close to CD quality.

Digital Audio Broadcasting or DAB for short is a Europe-wide standard for the digital transmission of radio signals.

Digital radio reduces the signals by means of the MPEG-1 compression process with no perceptible sound loss (similar to MP3).

As a result, instead of just one channel per frequency, up to nine channels can be broadcast on the same frequency. In addition, digital transmission allows an even greater variety of channels and special services: for example, with radio text and slide show (only in conjunction with MMI) you can receive images and other interesting information in your car.

Two different frequency bands are generally used for digital radio: Band III (174-240 MHz) and the so-called L Band (1,452-1,492 MHz). Band III is usually used by stations broadcasting beyond a local area, e.g. across large regions of the country. The L Band mainly offers local stations with limited coverage (e.g. stations broadcasting to one city).
