Sound Pure's Take
Honesty and detail are what this mic delivers! Josephson has married the Geffell omni 221 capsule with their own high-voltage body to give you the most detailed omni mic in the world! Also, you don't need a high-voltage mic pre - the magicians at Josephson have made their 200 volt amplifier body work on any standard 48 volt phantom power! The MK221 capsule is incredibly rigid, which is what offers so much detail and accuracy. Combined with the high-voltage body, the 617 is perhaps the most detailed omni-directional microphone we've ever experienced!
With so many microphone builders poring over technical drawings and schematics of 50-year-old Neumann and AKG condenser designs, David Josephson is constantly pushing the envelope rather than regurgitating. The C617 is a prime example of this effort. A far cry from the KM84s, C28s, or KM54s of yesteryear, the C617 delivers a clarity, depth, and level of definition that feels supernatural, yet more musical than other hyper-clean SDC options. Most notable to the C617 is the mic body, designed to be powered by 48V phantom, but capable of applying a mind-blowing 200V to the capsule.
From Josephson Engineering
The Josephson C617 is the second generation of our 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 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 sub- micron 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.
