What is DAB?

Over time analogue broadcasting will be replaced by digital broadcasting. Digital Audio Broadcasting is a digital radio replacement platform for FM and AM analogue radio. Already radio audiences for digital radio are increasing while analogue listening is starting to decline. 50.4% of Manchester radio listening is now digital. It’s the same picture all around the country.

DAB is a method of carrying the output of multiple radio stations simultaneously. This method is called multiplexing. A recent technical development allows for the cost of multiplexing to be reduced, which in turn allows for delivery of radio station output at a fair and proportionate price point.

This type of broadcasting has been operating as a trial over the last five years, and has already seen a flourishing of new radio station formats while creating an opening for a new wave of radio professionals and volunteer and community broadcasters. 

Added to this is the use of a further refinement – DAB+. This improves sound quality and with that, the all-important listening experience.

In terms of the environment, our DAB multiplex plans are good news. When the carbon footprint for a low power multiplex network is shared between twenty broadcast radio stations, the comparative size of that footprint is halved. 


M&S Digital will offer a larger potential audience than currently available, which will mean more people can hear the radio services we carry, meaning more listeners will be reached.

Our network of transmitters strategically placed around the city will ensure we are on target to cover the area shown in the map below with a stable and reliable transmission service.
