The AKG C451 B is a reference small diaphragm condenser microphone designed for professional studio recording. It is engineered to deliver the same acoustical behaviour as the original C451 EB paired with the CK1 capsule, first introduced in 1969.
The microphone employs a handcrafted capsule and transformerless preamplifier design, using surface mount technology to achieve low distortion, reduced weight, and high reliability. A high overload capability allows the microphone to handle high sound pressure levels without distortion, while an integrated high pass filter provides effective control of low frequency rumble and wind noise.
The AKG C451 B is phantom powered and features a fixed cardioid polar pattern, making it suitable for a wide range of close miking and detailed capture applications within the recording studio.
