Recording
Responding to growing demand, AKG decided to make the
C 451B with the same acoustic performance as the po-
pular original C 451EB + CK 1, with dramatically improved
specifications. Using an extremely light diaphragm, the
new C 451B is almost totally insensitive to handling noise.
Other features include an all-metal body for excellent pro-
tection from RF interference and high reliability for excel-
lent 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 over-
head miking.
