General
Sony's XDR-S40DBP is a red digital radio that features the latest in radio technology: DAB+, the successor of FM. DAB+, which stands for Digital Audio Broadcasting+, is an upgraded version of DAB, and offers a crystal-clear sound. It is much less prone to interference than analogue radio signals like FM, and takes up much less space in the ether, making room for more stations. Of course you can still listen to FM radio with the XDR-S40DBP, thanks to the inclusion of a rod antenna. The digital Sony radio can be connected to the mains power, but can also run on four (rechargeable) AA batteries. Thanks to its light weight and compact size you can easily take the Sony XDR-S40DBP with you wherever you go.
Operating the XDR-S40DBP
Sony's XDR-S40DBP is equipped with a single speaker with a 0.3-inch/0.66cm diameter and a power of 0.3 watt, which means it produces mono sound. Connect a pair of headphones to the 3.5mm jack output, however, and you can also enjoy your favourite radio stations in stereo. The digital radio is fitted with a number of controls, including a large volume knob on the side and several buttons on the front panel that allow you to switch between FM and DAB+, to select a radio station and to operate the menu. An orange-lit LCD display provides you with various information, such as the names of radio stations, presets, battery power and much more. With the development of DAB+ technology, it is quite possible that a lot of other information will be included in the radio signals in the future.
The benefits of DAB+
DAB+ has replaced the older DAB technology, and may well replace analogue FM technology too. Digital radio has many benefits compared to its analogue counterpart. A single DAB+ frequency can be used to transmit various stations, for instance, so you no longer need to search for specific frequencies. As digital signals take up less space in the ether, more room is available for other stations. DAB+ is used in several countries world-wide, particularly in Europe. In addition to the familiar public broadcasting and commercial stations that could be found via FM, many stations that were previously only available via cable or Internet radio can now also be found in the ether.
