Josephson C700A
Pressure Gradient Microphone with Continuously Variable Pattern, Class-A Electronics and 2 Capsules in One Housing
|
It looks like something out of The Jetsons, and the Josephson C700 series of mics really do have futuristic features. The C700A has two capsules; a transparent omni pressure capsule and a warm figure-8 gradient capsule; each one with it's own output. If recorded on separate tracks, both EQ AND pickup-pattern can be adjusted during mixdown. Hand-built by Josephson Engineering on a Custom Order basis!

Series Seven microphones provide unprecedented flexibility, as the directional pattern of the mic can be adjusted in use, during or after recording. C700 microphones include omni/pressure and figure-8/gradient capsules, each with a discrete output. The signals can be recorded on separate tracks, so the pattern can be selected in mixdown. The C700A allows any number of patterns to be derived for any single-point stereo or surround pickup. Pattern control is only one advantage of this technique.
Applying different equalization or dynamic control to the capsule signals makes entirely different mic characteristics – for instance the warmth of a gradient mic used close up for vocals might be combined with the transparency of a pressure mic in the highs, by rolling off the high frequencies in the gradient signal and the lows in the pressure signal before they are combined.
The C700A includes two capsules in one housing, a 16mm omni element similar to the KA11 capsule in the Series Six, and a 26mm figure-8 capsule. Completely neutral electronics, using the same cascode FET input, class-A active balanced output circuit found in the Series Six, are provided for each signal. Any directional pattern from omni to figure-8 may be selected by controlling the ratio of pressure to gradient signals.
The capsule assembly in the Series Seven is internally shock mounted, so that the mic may be attached directly to a stand through its yoke mount without any external accessories.
