Responding to growing demand, AKG decided to make the C451B with the same acoustic performance as the popular original C451EB + CK1, with dramatically improved specifications. Using an extremely light diaphragm, the new C451B is almost totally insensitive to handling noise. Other features include an all-metal body for excellent protection from RF interference and high reliability for excellent results under almost all conditions.
The C451B is an excellent tool for accurately capturing signals rich in transients such as drums, instruments with a percussive sound, acoustic guitar, or for overhead miking.
