Introducing Esfera, Sennheiser’s innovative 5.1 surround microphone system which elegantly creates immersive surround audio from a single pair of X/Y microphones. Esfera simplifies workflows for broadcast professionals by efficiently capturing authentic ambience using just two audio channels, and converting this audio information to 5.1 at any point in the workflow - live or in post-production. The Esfera system features two components: the SPM 8000 two-channel microphone unit, and the SPB 8000 surround processor unit.

Features:

  • Perfect support of broadcast workflows
  • Decoding done in real time or in post production
  • Record two tracks and decode to surround at any point in the workflow
  • High-quality 5.1 microphone when connected with SPB 8000
  • Very natural sound
  • Weather-proof and rugged components

SPM 8000
Two-channel microphone unit utilizes Sennheiser’s renowned RF condenser technology to deliver natural and detailed sound, transparency, ruggedness and high resistance to adverse climatic conditions. The system includes two compact, cardioid RF condenser microphones, suspended in an X/Y pistol grip with basket windshield and hairy cover. A Y-cable (XLR-5 to dual XLR-3) is also included.

SPB 8000
A 19” rack-mount processing unit, capable of generating a 5.1 surround signal from the SPM 8000 microphone unit, at sampling rates of up to 96 kHz. The SPM 8000 algorithm is precisely aligned with the SPM 8000 microphones, and offers a well-structured interface with user-definable presets. A web interface provides real-time access to all surround parameters like gain of the individual channels, front and surround focus, surround delay, filters and compressor, limiter and the treble boost.
