microphone for
high sound pressure levels
60 dBA - 186 dB
The 1/4″ microphone set consisting of the MV310 and the microphone capsule MK342 E has a constant pressure curve and is therefore optimized for correct acoustic measurements at interfaces or in acoustic couplers with extreme sound pressure levels.
MK342 E + MV310 set
1/4" IEPE microphone with
constant pressure frequency response
The static air pressure is compensated by means of a capillary to the preamplifier (back-ventilated) or by means of a side capillary (side-ventilated).
The membrane is protected against mechanical
damage by a protective grid.
