Josephson Engineering C700S
Multi-Pattern Condenser Stereo Microphone
The C700S is a single-point stereo microphone with infinitely variable pickup-pattern choices. It has three condenser capsules with separate outputs, allowing any variation of directionality to be selected at recording time or during mixdown.
Like the C700A, the C700S contains:
- A small-diameter single-diaphragm omni capsule measuring 16mm in diameter. It is a derivative of Josephson’s KA11 omni design, sharing the same backplate and 5-micron diaphragm.
- An edge-fed 34mm dual-backplate LDC capsule based on AKG’s CK-12. This capsule has two 5-micron, 26mm diaphragms and produces a Figure-of-8 response, a result of opposite polarizing voltages being supplied to the front and rear diaphragms.
To this pair of capsules, the C700S adds a second large-diaphragm capsule, identical to the first but mounted at 90°.
The capsule assembly is internally shock-mounted, negating the need for an external spider shockmount.
The additional figure-of-8 capsule allows the C700S to record mid-side or XY stereo signals, as well as the 5 primary surround channels. Summing just the two bidirectional signals allows the mic to produce a figure-of-8 response in any direction. See the user guide (link in sidebar) for details.
Each of the three condenser capsules has its own dedicated FET amplifier and transformerless output circuit.
The microphone has a single 7-pin XLR output connector.
