Josephson C700A Condenser Microphone

Josephson C700A Condenser Microphone

The Josephson 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.
