Regularly available across Western Europe, Canada, Australia, and some parts of Asia, these broadcasting systems use a more efficient coding scheme. Through the use of noise and multipath fading, reception quality is consistent throughout signal reception, whereas FM reception degrades slowly as the signal decreases. DAB+ also allows access to a wider range of radio stations, as well as interference-free digital reception. This, coupled with 0.8W+0.8W speakers, allows this radio to reproduce a clear stereo sound. A sleep timer allows a preset time delay before the radio automatically switches off to save power and a headphone jack offers private listening.
