Measurement microphone M 372

dynamicelectretomnidirectional

The 1/4" electret measurement microphone M 372 offers a sensor that can be connected directly to the analog audio inputs of computers or mobile devices. The Class 1 frequency response according to IEC 61672, the extraordinarily high sensitivity of 25 mV/Pa in this category and the 7 mm standard diameter are regarded as special advantages and are comparable to conventional measuring microphones. Electret capsule and preamplifier circuit form an inseparable unit in a cylindrical metal housing. The electrical connection of the measuring microphone is made via a microdot connector and a corresponding adapter cable to a two- or four-pin 3.5 mm jack plug. The measurement microphone can be calibrated with the aid of sound pressure calibrators operating in the dynamic range of the microphone, e.g. the 4010, using a 1/4" adapter. As optional accessories, we recommend the microphone holder MH 64 for diameter 7 mm, whose conical shape is matched to the sound field, and the windscreen W 3.
