Meet the system
The solution is called ESFERA the surround microphone system developed by Sennheiser. It enables you for the first time to generate and broadcast 5.1 surround sound using two ordinary standard audio cables. All you need is the SPM 8000 microphone on location and the SBP 8000 basic unit at any given point within the production or post-production process before the audio signal is aired. The compact built of the microphone unit, which can be mounted on a camera, allows even sideline interviews or the application in tight spaces.
