The predecessor to the AKG C451 B microphone was the classic C451 EB + CK1 studio mic that was a bestseller discontinued in '93. The C451 B 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. Operates on phantom power. AKG includes a stand adapter and windscreen with the C451 B microphone. 3-year warranty.
