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.

The matched pairs consist of two microphones that are within 1 dB to each other in sensitivity and also within 1 dB to each other in the range of 200 Hz to 15,000 Hz of the individual frequency response when used in cardioid mode and are selected from a large quantity of individual microphones using the described criteria by using a proprietary computer program.

Using this matched pair for stereo recordings utilizing various techniques will provide for a good and stable balance without frequency-dependent shifting of the stereo panorama.

The kit includes all the standard accessories of the individual package along with a stereo bar and proof of performance charts in an attractive carrying case (Soundtool case, middle size).
