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)

왘 Replace the “hairy” cover 6 by sliding it over the basket windshield and fastening its
snap fasteners.
Inclining the SPM 8000
왘 Loosen the locking lever 3, adjust the desired angle and tighten the locking lever 3
again.
Connecting the SPM 8000 to the SPB 8000/to audio devices
Connection data of the SPM 8000:
•
48 V ±4 V phantom power (P48, IEC 61938)
•
XLR-5 connector or
•
2x XLR-3 connector via Y-adapter cable
To connect the SPM 8000 to a camera/audio device with XLR-5 input:
왘 Connect the XLR-5 connector 4 of the SPM 8000 to the camera or audio device.
To connect the SPM 8000 to the SPB 8000 central unit or to an audio device with 2 analog
XLR-3 inputs:
왘 Connect the XLR-5 connector 4 of the SPM 8000 to the Y-adapter cable 5 (supplied).
왘 Connect the two XLR-3 connectors of the Y-adapter cable 5 (red = right channel, yellow
= left channel) to the inputs of the SPB 8000 central unit or of the audio device.
The inputs of the central unit are also marked red and yellow.
If you want to use the SPM 8000 digitally, you have to use an A/D converter.
