The predecessor to the AKG C 451 B microphone was the classic C 451 EB + CK1 studio mic that was a bestseller discontinued in '93. The C 451 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 C 451 B microphone. Features Identical acoustics to CK 1 cardioid polar pattern Can be run in un-balanced mode (still requires phantom power) phantom powered (9VDC to 52VDC) 20Hz to 20kHz frequency response Max SPL 155 dB when using -20dB pad selectable pad: 0dB, 1 dB, and 20dB selectable 75 or 150 Hz Bass rolloff filter High front-to-back rejection ratio great for live and drum micing Transformerless output Signal/noise ratio of 76dB.
