The C 547 BL is a condenser boundary layer microphone
with a hypercardioid pickup pattern. Its rugged construction
permits it to be used on the floor, where it can withstand
accidental footsteps. It has a switchable low frequency roll-
off filter to minimize footfalls on stage. The microphone
works as well on a tabletop.
Microphone sensitivity is 8.5 mV/Pa, and total harmonic
distortion (THD) is 1% at an acoustical operating level of
133 d
