The Josephson C705 is a FET large-diaphragm condenser microphone with a fixed cardioid polar pattern. It uses a single diaphragm cardioid capsule derived from the C715. The capsule uses a 5-micron gold-metallised diaphragm and boasts acoustic ports to create its cardioid polar pattern which provides improved directionality at low frequencies. The capsule provides a smooth and airy high end with enhanced proximity effect characteristic of single-diaphragm microphones.It also features the same discrete cascode input circuit and the symmetrical balanced transformerless output circuit of the 716 which is used for buffering the capsule as well as converting the impedance. As a result of its low impedance, the C705 works with a great range of preamps and input stages.
