While MHz is renowned for its satellite news-gathering trucks and HD trailers, a significant slice of its OB unit construction workload is made up of audio-only radio vehicles for major broadcasters such as the BBC. The world of audio broadcast is changing almost as rapidly as video — modern trucks often need to have the ability to transmit over IP as well as via the more traditional mast. And just as the transition to HD has provided new challenges in the world of video production, so the world of radio is having to prepare itself for the advent of multi-channel surround-sound broadcasting. The MHz team can advise on all of these requirements.
