Denmark's main commercial television station TV2 is using DPA d:screet 4080 cardioid lavalier microphones to transmit a series of highly unusual live political interviews for its 24-hour news channel.
The interviews are all conducted inside a Tesla electric sports car, which was first deployed by TV2 during the country's recent election campaign. The highly innovative and unusual mobile studio is entirely unmanned by TV2's technical staff and is instead operated remotely from the broadcaster's studios in Copenhagen.
Morten Brandstrup, head of News Technology at TV2, said: "We introduced the Tesla mobile studio during last year's election coverage because we wanted to present political candidates in a different environment. On each day we paired politicians of different political persuasions and had them talk to each other live to air while they drove the Tesla around the country. They knew that every word they said could be heard, but being in a car rather than a studio made their conversations much freer and more unexpected."
To capture the conversations, four d:screet 4080 supercardioid lavalier microphones are used in conjunction with a Wisycom wireless system. The microphones are fitted to the politician's clothing so that they can still be heard when they step outside the car, despite most of the conversations taking place within the Tesla.
"We carried out some acoustic testing with DPA consultant Eddy B. Brixen and the Tesla turned out to be a great environment for recording voices," Brandstrup added. "Thanks to the directional quality of the microphones the audio was perfect, which was really important because Udfordringen is a talk show and we wanted audiences to hear the politicians clearly without the distraction of background noises."
As well as DPA microphones, the Tesla SP85C was fitted with four cameras, internal lighting, four transmitters and 16 4G modems. Although the director was able to control the technology externally, the car was also fitted with a small live production set up consisting of a video and an audio mixer, which was located in the boot.
"Creating a studio in a car and letting politicians drive around without any journalists or technical crew present takes reporting to an entirely new level," Brandstrup concluded. "When you have two people sitting in a car they naturally start to talk to each other and that's what makes this space so special for interviews and debates."
The 'studio in a car' concept was so successful that TV2 has kept the Tesla on the road for its weekly political programmes.
