AKG Acoustics C547BL Folheto

C 547 BL

Boundary Layer Condenser Microphone

Description

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 dB. The equivalent noise floor is 22 dB-A. The
microphone operates on phantom powering over the range of
9 to 52 volts dc. The finish is matte black, and the
microphone can be painted any color to match decor.

The connector is a 3-Pin XLR.
