Precision and Quality Craftsmanship
The C 451 B continues AKG's legacy of precise craftsmanship, offering a fixed capsule to preamp design that eliminates mechanical issues, ensuring enduring quality and performance.
KEY FEATURES
Precise artistic work deserves precise artistic craftsmanship. A classic by now, the CMS Series CK 1 capsule from AKG was a best seller from the moment it was launched in 1969.
Comprising a range of interchangeable capsules and preamps 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 the C 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 the mechanical 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 451 B is an excellent tool for accurately capturing signals rich in transients such as drums, overhead miking, or other instruments with a percussive sound. The airy sound, high overload limit of the capsule and electronic circuitry, and improved engineering details of the C 451 B are a solid foundation for creating another legend.

KEY BENEFITS
Low Handling Noise
Utilizing an extremely light diaphragm, the C 451 B microphone is designed to be almost completely insensitive to handling noise, making it ideal for high-quality recording in various settings.
High Transient Signal Accuracy
This microphone excels at capturing transient-rich signals like drums and percussive instruments, thanks to its high overload limit and a design optimized to faithfully reproduce sharp sound peaks.
