Beyerdynamic MM 1 – Professional Measurement Microphone

The Beyerdynamic MM 1 is a precision measurement microphone designed for applications requiring the highest level of accuracy – from studio room acoustics measurement and PA system setup to research and development in the audio industry. Featuring an omnidirectional polar pattern and a linear frequency response at 90° (calibrated in the diffuse field), the MM 1 delivers accurate, uncolored sound reproduction without distortions caused by the microphone body.

Product Features

• Ideal for measuring acoustics in various environments
• Linear frequency response at 90° (diffuse-field calibration)
• Individual calibration data for free-field measurements at 0° and 90° (on request)
• Slender metal housing minimizes influence on the sound field
• Handmade in Germany
• Measurement precision within +/- 1.5 dB between 50 Hz and 16 kHz
• High-quality back-electret condenser capsule
• Rugged protective case included
• Also suitable as an unconventional option for instrument or vocal recording

Professional Measurement Precision

The MM 1 has been engineered to deliver maximum measurement accuracy. Its slim housing reduces the build-up of sound pressure at high frequencies, while the precise calibration of each unit ensures consistent and repeatable results.
