The Tournament of Tournaments is followed by 40 Million listeners. The BBC relies upon a MADI Router from DHD for their radio transmissions from Wimbledon.

The vital switching tasks for the worldwide radio broadcasts from Wimbledon, are under the control of a DHD RM 4200 MADI Router, configured and delivered in record time by Thum + Mahr to the BBC Outside Broadcast Service in the middle of May.

All 6 courts have been equipped with decentralised audio I/O frames, connected to the central router via MADI links. Consequently the BBC OB Service, which is responsible for outside broadcast productions, is putting its faith in imported engineering including the use of DHD technology also for live broadcasting. The compact rack units - individual frames require only 6U of rack space, and run without fans – provide an amazing 384 inputs and outputs.

The BBC broadcasts over 100 hours of commentaries from Wimbledon on BBC Radio Five Live on the medium wave, and Five Live Sports Extra on DAB. The BBC World Service also takes feeds of the live commentaries, which it then relays worldwide.

The BBC observes, "Some 40 million listeners worldwide can keep up-to-date via BBC World Service's English programmes, plus other language services."

The DHD MADI Router is driven by the user friendly DHD Router Control Software. Up to 5 PC’s running the Router Control Software can be operated simultaneously by BBC engineers to control the MADI Router via a control area network. Thanks to configurable switcher masks, each of the BBC Router Control PC’s have access to individual workspaces that control fully independent switching regimes.
