A classic by now, the CMS Series CK 1 capsule from AKG was a best seller from the moment it was launched in 1969. Comprising a range of interchangeable capsules and preamps as well as then innovative, dedicated accessories, the CMS Series from AKG quickly became a legend. It was discontinued in 1993.
Responding to growing demand from recording engineers, AKG decided to produce the C 451B with identical acoustical behaviour of the popular original C 451EB + CK 1 microphone again, with dramatically improved specifications and outstanding price/performance.
The capsule of the new version is fixed permanently to the preamp to eliminate the mechanical problems of the screw joint. Using an extremely light diaphragm, the new
C 451B is almost totally insensitive to handling noise. An all-metal body provides excellent protection from RF interference and the microphone is rugged enough to give
excellent results even under very harsh conditions.
Features:
- A switchable highpass filter at75 Hz or 150 Hz prevents low-end
distortion due, e.g., to rumble or wind.
- A switchable 10-dB/20-dB preattenuation pad increases the
microphone’s SPL capability.
- An all-metal body provides excellent protection from RF interference.
- The capsule is permanently fixed to the preamp to increase
overall stability under mechanical stress.
- Identical acoustics of the legendary CK 1.
- Rugged construction.
- Ruler-flat on-axis frequency response.
- Precise, nearly frequency independent cardioid.
- Extremely accurate signal transfer.
