Beyerdynamic MM 1 is a precision condenser measurement microphone specifically designed for sound reinforcement and acoustic analysis. It is ideal for use with spectrum analyzers to measure the frequency response and sound pressure levels of loudspeaker systems, making it perfect for research, development, and room acoustic testing. Its slim, tubular construction minimizes acoustic interference, ensuring accurate high-frequency readings and a natural sound reproduction thanks to its linear frequency response.
Handcrafted in Germany, the MM 1 is calibrated for diffuse-field measurements and provides exceptional accuracy with low self-noise and high SPL handling. Its omnidirectional pickup pattern captures sound evenly from all directions, while the electronically balanced output ensures clean signal transmission for precise measurement applications in studios, live venues, and laboratories.
