AKG Acoustics CK 91 Blue Line Cardioid Microphone Capsule 20 to 20000 Hz Frequency Range -
The AKG CK 91 Blue Line Cardioid Microphone Capsule is a cardioid 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 cardioid polar pattern is effective in eliminating noise and ambiance at the off-axis sections of the capsule. The result minimizes feed-back and allows the CK91 to be used to spot capture instruments and vocals for sound reinforcement and crucial recording. The CK91 is powered with the AKG SE-300B power supply.
