The Beyerdynamic MM1 Measurement Microphone is designed specifically for measuring sound reinforcement and PA systems. Ideal for spectrum analyzers allowing frequency response and sound pressure levels of speakers to be monitored, the compact MM1 can be mounted unobtrusively.

The Beyerdynamic MM1 Measurement Microphone is the ideal microphone for the measurements of audio signals in the research, development, for reverberation testing and other applications. It is designed to work with spectrum analyzers for measuring frequency response and sound pressure levels of loud speaker systems. The Beyerdynamic MM1 mic's narrow tubular construction ensures that the microphone has negligible influence on the sound field so that an increase in pressure level is avoided due to the linear frequency response.
