C 451 B/ST

The matched pair consists of two C 451 B microphones that are within 1 dB to each other in sensitivity and also within 1 dB to each other in the range of 200 Hz to 15,000 Hz of the individual frequency response when used in cardioid mode and are selected from a large quantity of individual microphones using the described criteria by using a proprietary computer program.

Using this matched pair for stereo recordings utilizing various techniques will provide for a good and stable balance without frequency-dependent shifting of the stereo panorama.

The kit includes all the standard accessories of the individual package along with a stereo bar and proof of performance charts in an attractive carrying case (Soundtool case, middle size).

The small-diaphragm C 451 B by AKG is unsurpassed in capturing transient-rich sources like percussion, guitar, and drums. Its extremely light diaphragm makes it nearly immune to handling noise, while an all-metal body protects against RF interference. Features a three-way sensitivity switch and three-way low-cut switch. Includes case, clip, and windscreen.


  • 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.
