The Esfera surround microphone system
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 microphone –
supplied complete with basket windshield, suspension with pistol grip, “hairy” cover and
cable – and the SPB 8000 central unit that converts the signals of the microphones into a
complete 5.1 audio signal.
The SPM 8000 stereo microphone
Two RF condenser microphone capsules in XY configuration are at the core of the SPM 8000
stereo microphone. When used in conjunction with the SPB 8000 central units, the wo microphones can create a complete 5.1-channel surround sound effect. The microphone is supplied complete with basket windshield, suspension with pistol grip, “hairy” cover and stereo
cable (XLR-5 to 2x XLR-3).
• Can be used as a high-quality stereo microphone or – with the SPB 8000 – as a compact
5.1 microphone
• Very natural, detailed sound
• Weather-proof and rugged
• Exceptionally low inherent self-noise prevents masking of delicate sound structures
• Symmetrical transducer technology ensures extremely low distortion
• Transformerless and fully floating balanced microphone outputs: no coupling of
spurious signals
• High output signal voltage ensures interference-free signal paths
• Supplied complete with basket windshield, suspension with pistol grip, “hairy” cover
and stereo cable (XLR-5 to 2x XLR-3)
