The MP30 condenser microphone set consisting of a ½” microphone capsule with preamplifier can be connected to all measuring devices with IEPE sensor supply.
The low background noise of less than 16 dB(A) and the linear frequency response from 4 Hz to 20 kHz is ideal for almost any precision measurement.
