DAB radio - excellent reception everywhere
Digital radio is the future of radio reception. DAB and DAB+ radios receive a large number of stations and additional information, for example about the current traffic situation, the weather service or other important events.

What is a digital radio?
DAB is very digital audio broadcasting. This is a transmission standard for the reception of digital radio programs via terrestrial antennas.
Digital radios can be used anywhere thanks to the wireless, terrestrial reception. Therefore, they are also used as car radios or are equipped with accumulators for mobile use. Of course, there are also the classic stationary radios with DAB+ reception and other additional functions.
With a digital radio you have reception virtually everywhere: In the car, in the living room, in the garden, on holiday and elsewhere.
The range of transmitters is considerably larger with digital radio than with the previous reception channels via FM and FM. The more frequencies that can be allocated to broadcasters are largely due to two technical advances:
- On the one hand, the better accuracy of the target in digital transmission, in which radio waves on neighboring frequencies do not interfere with each other.
- On the other hand, the compression of the source signals for the sound, which has no effect on the sound quality. On the contrary, digital radio reception is less susceptible to interference and offers optimum listening pleasure.
Bad reception, crackling and rustling are a thing of the past. The technology behind digital radio prevents the transmission waves of digital radio transmitters from overlapping and interfering with each other. Thus, DAB and DAB+ offer the highest sound quality.
DAB or DAB+ which technology is better?
DAB and DAB+ are not compatible with each other. However, DAB+ reception can be retrofitted to DAB radios and other devices such as sound systems and computers. DAB+ adapter can be found here.
Tip: Many of the newer radios support both DAB/DAB+ reception as hybrid devices.
DAB receivers for digital radio reception have been available since 2004. However, the sales figures never reached that of the older FM transmission technology. The DAB could completely replace FM radio, was never expected in the following years. Digital Media Broadcasting (DMB) was also not accepted by consumers and has almost disappeared from the market, with the exception of France.
DAB has already been used as the transmission standard. DAB+ is the successor to DAB. DAB+ is likely to become a winner in the coming years. A comparison between DAB and DAB+ shows why:
|DAB radio||Additional advantages with DAB+ radio|
|reception of DAB stations||reception of DAB+ programs|
|automatic search||many additional functions (e.g. weather service, traffic information, storing your favorite stations)|
|large program selection||receives even more programs|
|good sound quality||even better sound quality|
Which radios are available for digital reception?
As a radio version, digital receivers are basically the same specifications as before:
Radios for everyday use:
- Kitchen radios are available in different versions.
- Bathradios are approved for use in damp rooms.
- Portable radios have their name from the distinctive rectangular shape, reminiscent of a suitcase.
- Table radios can be placed on flat surfaces such as tables or shelves.
- Chassis radios are mounted under hanging cabinets or shelves or embedded in a wall.
- Construction site radios are robust and therefore suitable for use in harsh environments.
- Outdoor radios can usually be operated with batteries or rechargeable batteries and are optimally designed for use on the move.
- Pocket radios are small, compact radio receivers.
- Socket radios are plugged directly into a socket. This is then the power source and holder at the same time.
Radios with special functions:
- Internet radios can receive audio content not only terrestrial via their antenna, but can also be integrated into a WLAN or LAN network and thus play content from online libraries or live streams from radio stations.
Note: Internet reception requires an Internet connection.
- Radio alarm clocks have an alarm function that switches on the radio at a preset time.
- CD radios have a CD compartment for playing compact discs. Radios with cassette decks are still available.
These functions and interfaces should be considered when buying a digital radio
In addition to the digital transmission paths DAB and DAB+, multi-function radios also offer reception via FM, AM or Internet.
Tip: Other interfaces for Bluetooth®, Near Field Communication (NFC), USB ports, LAN, and Wi-Fi options for Internet radio are common ways for modern devices to receive additional media sources. Look for alternative input interfaces when you sometimes don't want to listen to the original radio stations.
For mobile radio reception, you need a radio that can also be operated with batteries or rechargeable batteries as an alternative to the power supply via the socket. Some radios can be powered via a USB port, for example, on a laptop.
As a special power supply for outdoor use, there are solar radios as well as radios, which can be charged with a crank via dynamo.
Interfaces are important for connecting peripherals such as speakers, microphones or headphones.
There are, on the one hand, the interfaces at the input of the radio, that is, those via which audio contents can be played. These include antennas, but also SD memory cards with music files, microphones, WLAN devices or LAN connections for Internet radios.
The interfaces at the output of the radio are required for subsequent playback devices. These are, for example, jack sockets for loudspeakers, digital audio outputs, headphone connections or CD players.
Practical tip: If you want to integrate the new radio into an existing audio landscape, make sure that the appropriate connections for your other devices are available in sufficient numbers. Some interfaces can be retrofitted via adapters.
Questions and answers
Can I use my digital radio abroad?
Yes. Other European countries are also relying on the expansion of digital radio broadcasting with Digital Radio Broadcasting (DAB). Before traveling, find out whether DAB or DAB+ offers the wider range of radio programs in the destination country.
Where can problems occur with DAB and DAB+ reception?
Few failures in the reception of digital radio are only to be expected where the transmission waves cannot reach. For example, in Dick-walled cellars or in buildings with defense shielding against radio rays. As a solution, an antenna extension is suitable here, which moves the receiving location to a place where radio reception is possible, for example outside the window. External radio antennas can be found here.
Is it worth buying a DAB radio right now or should I ich better put it on DAB+?
Hard to say. Some newer models in digital radios support both reception standards. DAB is technically already regarded as outdated by DAB+, but even the old FM radio stations can still be received. It is best to find out in advance which transmission types your favorite programs will be broadcast. With DAB radios with USB connection as input interface, DAB+ reception can be easily retrofitted later.
