IEPE microphone set MP30 consisting of a ½” microphone capsule with preamplifier can be connected to all measuring devices with IEPE sensor supply.
MP30 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 4 Hz to 20 kHz is ideally suited for almost any precision measurement.
