The predecessor to the AKG C451 B microphone was the classic C451 EB + CK1 studio mic that was a best-seller discontinued in '93. This C451 B reference mic provides identical acoustical behavior to the CK1, with dramatically improved specs. It features a precise, nearly frequency-independent cardioid pattern, a transformerless output stage, selectable 10dB and 20dB preattenuation pads, and switchable high-pass filter. It operates on phantom power.

AKG includes a stand adapter and windscreen with the C451 B microphone. It also comes with a 3-year warranty.
