AKG 451-B

Cardioid Condenser Microphone Daily Rate: $20

Features | Technical Specifications | Support

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.

FEATURES:

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
