Josephson C617SET - Omnidirectional microphone supplied with Microtech Gefell MK221 Capsule

Josephson C617SET

The Josephson C617SET omnidirectional microphone designed for the most critical sound recording and measurement applications. The C617SET is supplied with a Microtech Gefell MK221 capsule. The dynamic range is dependent on the inherent noise of the microphone capsule and the limits of P48 phantom power. The Josephson cascode FET front end circuitry introduced in the C606 is further refined in the C617, combined with our traditional balanced bipolar class-A symmetrical output stage.

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.
