  • Esfera is a surround microphone system which is easy to install and very easy to use. Esfera provides 5.1 surround sound from just two channels, making complicated surround mic installations a thing of the past. The system consists of the SPM 8000 stereo and the SPB 8000 processing unit that converts the signals of the microphones into a complete 5.1 audio signal. The SPB 8000 processing unit converts the signals of the SPM 8000 stereo microphone into a complete 5.1 audio signal.

    Features

    • Supplies microphones with 48 V phantom power
    • Input switchable between analog and digital AES3 signals
    • Switchable compressor
    • 4 programmable presets for storage of 5.1 surround parameters
    • SPB 8000 adjustable via a web interface

    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, sold separately or as part of a complete system package, available at a special introductory price.
