Product Description
Additional Information
  • Product Description

    The Josephson C617 Set is the second generation of Josephson Engineering's high voltage metal diaphragm omnidirectional microphone, suitable for the most critical sound recording and measurement applications. It operates from standard P48 phantom power yet provides full 200 volt polarize potential for a lab grade standard “half inch” microphone capsule. The C617SET is supplied with a Josephson branded Microtech Gefell MK221 capsule. For music recording, the Josephson balanced symmetrical circuitry together with a submicron thickness metal diaphragm capsule translate to the purest, most open sound possible. Pickup of sound pressure alone results in no proximity effect, very low sensitivity to wind noise, and phase accuracy that cannot be obtained with directional microphones. Spot-miking applications or overall stereo pickups using spaced pairs take on a new level of detail and precision not possible with other types. The small capsule size results in a nearly perfect omnidirectional pattern for accurate pickup of the whole acoustic environment.
