MP401 Microphone

MP401 is 1/4" free-field prepolarized microphone. Its small size ensures a lower interference and reverberation influence of its presence in the sound field.

MP401 conforms to IEC 61672 Class 1 standard. MP401 can make the test at up to 170 dB, which makes MP401 the best choice for high frequency and high intensity measurement.
