C 451 B
Identical acoustics to legendary CK 1
Precise, nearly frequency independent cardioid
Extremely accurate signal transfer and ruler-flat on-axis frequency response
Also available as a matched stereo pair
Responding to growing demand, AKG decided to make the C 451 B with the same acoustic performance as the popular original C 451 EB + CK 1, with dramatically improved specifications. Using an extremely light diaphragm, the new C 451 B 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 C 451 B 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.
Also available as a matched stereo pair C 451 B/ST with complete accessories in a carrying case (Soundtool case, middle size).
