  • The AKG CK31 is a modular cardioid microphone capsule designed for use with the AKG GN series, HM 1000, and LM 3 gooseneck, hanging and lavalier microphone fixtures. The cardioid polar pattern minimizes noise and ambiance at the off-axis (sides) of the microphone. The result increases directivity and provides high gain-before-feedback response when using near speakers or monitors.
