Professional audio calibration demands precision, and the beyerdynamic MM 1 measurement microphone rises to meet this challenge with exceptional accuracy. This specialised microphone has been engineered specifically for calibrating studio environments, PA systems, and ELA installations, making it an indispensable tool for audio professionals who require reliable acoustic measurements.
The MM 1's distinctive slim housing design, featuring a protruding microphone capsule, minimises interference with the sound field being measured. This thoughtful construction prevents the pressure build-up that commonly occurs at higher frequencies with bulkier measurement devices, ensuring more accurate readings across the frequency spectrum.
When paired with a spectrum analyser, this microphone excels at both frequency response analysis and sound pressure level verification of loudspeaker systems. Its transmission pattern has been carefully optimised to achieve perfectly linear frequency response when measuring diffuse sound fields, which significantly streamlines the calibration process for multiple studio monitors and speakers.
Beyond studio applications, the MM 1 proves invaluable for acoustic research and industrial sound analysis, offering the same precision and reliability that audio professionals have come to expect from beyerdynamic's measurement solutions.
