C12

Original Vintage Valve Condenser Microphone with nine remotely-controlled polar patterns.

Nine different directional characteristics can be selected by means of a remote control unit without any change in frequency response or sensitivity. In addition to three basic characteristics, omni-directional, cardioid and bi-directional, six intermediate patterns (including hypercardioids) are available. The S 12 control unit is connected to the N 12 power supply unit by the RL 12 remote control cable, and the power supply unit to the micro­phone by the MK 12 mic cable.
