AKG C451 B Reference Small-Diaphragm Cardioid Condenser Microphone

The AKG C451 B is a small-diaphragm condenser microphone with the identical acoustical behavior of its predecessor, the C451 EB + CK1 capsule.

With its airy sound, high overload limit and improved engineering details, the C451 B continues the success story of this legend. The roadworthy design around the handcrafted capsule and the low-noise preamp electronics ensure impressive results even under very harsh conditions.
