C 451B - It was W• Rugged construction.

A classic by now, the CMS Series CK 1 capsule from AKG was a best seller from themoment it was launched in 1969. Comprising a range of interchangeable capsules andpreamps as well as then innovative, dedicated accessories, the CMS Series from AKG
quickly became a legend. It was discontinued in 1993.
Responding to growing demand from recording engineers, AKG decided to produce theC 451 B with identical acoustical behaviour of the popular original C 451 EB + CK 1
microphone again, with dramatically improved specifications and outstanding
price/performance.
The capsule of the new version is fixed permanently to the preamp to eliminate themechanical problems of the screw joint. Using an extremely light diaphragm, the new
C 451 B is almost totally insensitive to handling noise. An all-metal body provides
excellent protection from RF interference and the microphone is rugged enough to give
excellent results even under very harsh conditions.
The C 451B is an excellent tool for accurately capturing signals rich in transients suchas drums, overhead miking, or other instruments with a percussive sound. The airysound, high overload limit of the capsule and electronic circuitry, and improved engineering details of the C 451B are a solid foundation for creating another legend.

• Protected againstelectrostatic and magneticinterference.
• Selectable 10-dB and20-dB preattenuationpads.
• Switchable highpass filter(75 Hz or 150 Hz,
12 dB/octave).

The capsule is permanently fixed tothe preamp to increase overall stability
under mechanical stress.

• Operates on phantom
power to DIN/IEC between
12 V and 48 V.

A switchable 10-dB/20-dB preattenuation pad increases the microphone'sSPL capability when close-miking
high-energy sound sources or driving
preamps or mixers with limited headroom.

• Complete with SA 40 standadapter and W 90windscreen.
• Each microphone comeswith its own individual
frequency response plot.

A switchable highpass filter at 75 Hz
or 150 Hz prevents low-end distortiondue, e.g., to rumble or wind noise.
