AKG's C451 B (AKG-C451B) is the latest model in the C 451 series that dates back to 1969. It is a cardioid only design with a permanently fixed capsule (a departure from the previous modular system). The acoustics of the original cardioid capsule, CK 1, are modeled and matched in the current version, producing the unique overall rising frequency characteristics. The rise is no more than 3 dB and is broadly centered around 12 kHz. Its transformer-less preamp uses surface mount technology and, therefore is lighter, yet more rugged than its predecessor. Switchable 10 and 20 dB pads are now integrated. Maximum sound pressure levels in the range of 155 dB (in the 20 dB sensitivity position) can be attained with no greater than 0.5% distortion. A selectable low frequency, or bass roll-off option, provides 12 dB per octave attenuation below 75 or 150 Hz.
