The 1/4" electret measurement microphone M 373 is a sensor that can be connected directly to signal inputs with 48 V phantom powering commonly used in audio measurement technology. Typical applications are room acoustic measurements or the calibration of sound reinforcement systems. The Class 1 frequency response according to IEC 61672, the extraordinarily high sensitivity of 25 mV/Pa and the 7 mm standard diameter are special advantages and are comparable to conventional measurement microphones. Electret capsule and preamplifier circuit form an inseparable unit. The electrical connection of the measuring microphone is made via an XLR connector. The measuring microphone can be calibrated with the Pistonfon 5002 as well as common sound pressure calibrators using a 1/4" adapter.
