The AKG C 12 is a studio condenser microphone of the highest professional quality. It has been specially designed for use in sound recording and broadcasting studios.
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 microphone cable.
