Sennheiser SPB 8000

Overview

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.
