The AKG CK33 is a modular hyper-cardioid microphone capsule designed for use with the AKG GN series, HM 1000, and LM 3 gooseneck, hanging and lavalier microphone fixtures. The hyper-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.

The wide frequency response of 50Hz to 20kHz minimizes low frequency noise caused by wind and proximity effect while reproducing audio signal with great accuracy and rich detail. The dual wind screen design employs an outer layer which disperses initial wind stream while the second layer further diffuses the wind stream before reaching the diaphragm. The module design allows quick and easy capsule replacement for added flexibility.
