The C 451B is a updated rerun of a classic AKG
condenser microphone, the C 451 EB + CK 1.
The new C 451B, however, uses a fixed capsule
to eliminate the mechanical problems of the
original modular design. The microphone is the
perfect choice for any application where sounds,
particularly their transient content, need to be
captured with maximum accuracy.
Owing to its extremely light diaphragm, the
microphone is highly insensitive to handling
noise. An all-metal body provides efficient pro-
tection from RF interference and the microphone
is rugged enough to give excellent results even
under very harsh conditions.
A switchable 10-dB/20-dB preattenuation pad
increases the microphone's SPL capability when
close-miking high-energy sound sources or driv-
ing preamps or mixers with limited headroom.
A switchable highpass filter at 75 Hz or 150 Hz
prevents low-end distortion that may be caused,
e.g., by rumble or wind noise. The slope of the fil-
ter is 12 dB/octave and its corner frequency (3 dB
down point) is selectable at 75 Hz or 150 Hz.
