XLR Microphone Class 1

MP30-XLR condenser microphone set consists of a ½” microphone capsule with preamplifier and MP48 IEPE-XLR adapter. 

It can be connected to all USB audio devices with 48 volt phantom power.

MP30-XLR is a class 1 measurement microphone according to the WS2F frequency response industry standard.

The low noise floor of less than 16 dB(A) and the linear frequency response of 10 Hz to 20 kHz is ideally suited for almost any precision measurement.
