The beyerdynamic MM 1 Measurement Condenser Microphone is a versatile and high-quality microphone designed specifically for acoustic measurements. Whether you're measuring studio rooms, PA and ELA systems, or monitoring sound pressure levels, the MM 1 delivers accurate and reliable results. Handcrafted with precision in Heilbronn, Germany, the MM 1 features a high-quality back electret condenser capsule that ensures a linear frequency response at 90°. This means that you can trust the microphone to provide accurate measurements without any distortion or frequency bias. One of the standout features of the MM 1 is its low tolerance of ±1.5 dB in the range between 50 Hz to 16,000 Hz. This makes it incredibly reliable and perfect for those looking for precise measurements in a wide frequency range. Additionally, the microphone comes with individual calibration data for 0° and 90° free-field measurement, allowing you to fine-tune your measurements for even greater accuracy. With its slim housing and protruding microphone capsule, the MM 1 minimizes its influence on the acoustic environment, ensuring that your measurements are not compromised by the microphone itself.
