The AKG CK 92 Blue Line Omnidirectional Microphone Capsule is an omni-directional capsule with signal characteristics that allow the microphone to be used in a variety of applications. The miniature capsule features a flat wide frequency response of 20Hz to 20kHz allowing smooth accurate signal reproduction without coloration. The omni-directional polar pattern provides a generous pick up response at the direct and off-axis sections of the microphone capsule. The result is smooth, even signal character and frequency response at all angles with minimal noise due to handling. The CK92 is powered with the AKG SE-300B power supply.
