Details
I/O: 3-pin XLR balanced output (SET version, supplied with Microtech Gefell MK221 capsule); C617 body-only version accepts other 1/2-inch capsules
Notable use: Reference-standard omni for critical music recording and acoustic measurement; spot-miking and spaced-pair stereo where phase accuracy and absence of proximity effect are required
Notes: Second generation of Josephson's high-voltage metal-diaphragm omni; operates on standard P48 phantom but internally generates full 200V capsule polarization. SDC by capsule size (half-inch).
