    AKG C 451 B Cardioid Condenser Microphone Product Description

    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 until it was discontinued in 1993.

    Responding to growing demand from recording engineers, AKG decided to produce the C 451 B with identical acoustic behavior of the popular original C 451 EB + CK 1 microphone again, with dramatically improved specifications and outstanding price/performance.

    The capsule is fixed permanently to the preamp to eliminate the mechanical problems of the screw joint. Using an extremely light diaphragm, the 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.
