When accuracy matters, your measurement mic needs to deliver uncompromising results. The beyerdynamic MM 1 measurement microphone is designed for precise acoustic analysis with a linear frequency response, omnidirectional pickup and tight ±1.5dB tolerance from 50Hz–16kHz. Built around a high-quality back electret condenser capsule and diffuse-field calibration at 90°, it provides reliable, repeatable measurements for studio tuning, PA system alignment and sound reinforcement analysis. Whether you're working live or in controlled environments, the MM 1 gives you the confidence to make informed decisions based on accurate data.
Linear Response for Accurate Room Analysis
The MM 1 is engineered to deliver consistent, transparent measurement results across a wide 20Hz–20kHz frequency range. Its diffuse-field calibration ensures a flat response when measuring ambient sound fields, making it ideal for evaluating room acoustics and speaker performance without extensive setup. When paired with a spectrum analyzer, it allows you to monitor both frequency response and sound pressure levels with precision, streamlining system calibration and optimization.
Minimal Acoustic Interference by Design
Featuring a slimline metal housing with a recessed capsule, the MM 1 is designed to minimize its own influence on the sound field. This reduces high-frequency buildup and ensures more accurate readings, even in complex acoustic environments. Its lightweight, compact form factor makes it easy to position exactly where you need it, whether you're measuring studio monitors, PA systems or environmental sound conditions.
Pinpoint Accuracy With Individual Calibration
Handmade in Germany, each MM 1 is individually tested and calibrated to meet strict performance standards. Upon request, detailed calibration data for both 0° and 90° free-field measurements is available, providing an additional level of precision for professional applications. Built with durable materials and designed for long-term reliability, the beyerdynamic MM 1 mic is a trusted tool for engineers, researchers and audio professionals who require dependable, high-accuracy measurement performance.
