For capturing audio, the SPM 8000 Esfera Stereo Microphone by Sennheiser makes complicated surround mic installations a thing of the past. This microphone can be used to provide 5.1 surround sound from two channels of audio, for applications such as recording, live sound, theater, rehearsals, and much more. It features two RF cardioid condenser microphone capsules in an XY configuration, with a frequency response of 35 Hz to 20 kHz each, and is powered by 48V phantom power. When used in conjunction with the SPB 8000 central unit, (sold separately) the two microphones can create a 5.1 channel surround effect. The microphone is supplied complete with basket windshield, suspension with pistol grip, "hairy" cover and stereo cable (XLR-5 to 2x XLR-3).
