AKG C 451B Condenser microphone cardioid-10/20db PAD, 75/150Hz

Precise transient capture for acoustic guitar, percussion and overheads

Precise artistic work deserves precise craftsmanship. The CK 1 capsule from AKG’s CMS series, now a classic, has been a bestseller since its launch in 1969. AKG’s CMS series, comprising a range of interchangeable capsules and preamplifiers, as well as specialised accessories that were innovative at the time, quickly became legendary. It was discontinued in 1993.

In response to growing demand from sound engineers, AKG decided to reintroduce the C 451 B with the same acoustic characteristics as the popular original C 451 EB + CK 1 microphone – featuring significantly improved technical specifications and excellent value for money. The capsule of the new version is permanently attached to the preamplifier to eliminate the mechanical problems associated with the screw connection. Thanks to the use of an extremely lightweight diaphragm, the new C 451 B is almost completely immune to handling noise. An all-metal housing offers excellent protection against RF interference, and the microphone is robust enough to deliver outstanding results even under very harsh conditions.

The C 451 B is ideal for the precise recording of signals rich in transients, such as drums, overhead miking or other instruments with a percussive sound. The airy sound, the high headroom of the capsule and the electronics, as well as the improved technical features of the C 451 B, form a solid foundation for the creation of yet another legend.
