Josephson C700S

The Josephson C700S microphone has three capsules one 16mm pressure element, mounted between two 26mm gradient elements which are at right angles to each other. The gradient capsules face 45 degrees toward left and right, while the pressure capsule faces forward. Any coincident stereo pickup can be derived from mixing these three signals together, and like the C700A, the signals can be recorded individually and all aspects of image width and pattern control may be adjusted in the mixdown.

Series Seven microphones from Josephson independently sample the pressure and pressure gradient components of sound, providing separate outputs so that the mixer can choose the directional pattern by combining different ratios of these two signals. This gives unprecedented flexibility, as the reach of the mic can be adjusted in use. Mixing the two signals equally yields a cardioid using a little more pressure than gradient makes a wide cardioid, subcardioid or hypo-cardioid. Using a little more gradient than pressure makes a hyper-cardioid or supercardioid. The pressure signal by itself has an omnidirectional pattern, while the gradient signal has a figure-8 pattern. The two signals can even be recorded on separate tracks, so the pattern can be selected in mixdown. Pattern control is only one advantage of this technique.

Applying different equalization or dynamic control to the two 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 highs in the gradient signal and the lows in the pressure signal before they are combined. The basic C700A includes two capsules in one housing, a 16mm pressure element similar to the KA11N capsule in the Series Six, and a 26mm gradient capsule. Completely neutral electronics, using the same circuit found in Series Six, are provided for each signal.

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.
