NotesThe Studio Projects C1 is an externally polarized cardioid pressure gradient transducer microphone with FET impedance converter. Diaphragm material is 6μm mylar for natural reproduction of vocals and instruments. It features dual selectable pads and high pass filters for a total of nine possible modes of operation. The output circuitry is active and is capable of driving long cable runs.
