C 547BL

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.
