Earthworks Audio
Looking for top-tier laboratory precision and extended ultrasonic bandwidth for critical acoustic measurements? The Earthworks M50 is a flagship 50kHz omnidirectional measurement microphone engineered to meet or exceed ANSI Type 1 and IEC 61094 requirements for high-end loudspeaker design, scientific research, and complex audio system alignment.
Achieve reference-standard data accuracy, ultrasonic fidelity, and absolute time-domain clarity with the Earthworks M50 50kHz Omnidirectional Measurement Microphone. Designed for high-precision acoustic analysis, high-end loudspeaker R&D, scientific research, and complex audio system alignment, this flagship free-field condenser microphone delivers an exceptionally flat frequency response extending from 3Hz all the way to 50kHz.
Why Choose the Earthworks M50 Measurement Microphone?
When measurements extend into ultrasonic frequencies or demand extreme impulse precision, standard test microphones fall short. The Earthworks M50 is engineered to meet or exceed ANSI Type 1 and IEC 61094 requirements, providing laboratory-grade performance across both frequency and time domains. Its exceptionally consistent omnidirectional polar pattern guarantees uniform pickup from all direct and off-axis angles, ensuring your FFT-based measurement platforms capture the true acoustic behavior of any component or physical environment.
Key Performance Features
- Flagship 50kHz Frequency Range: Features an ultra-wide, flat response spanning 3Hz to 50kHz (+1/-3 dB) for uncompromised subsonic and ultrasonic acoustic capture.
- True Omnidirectional Polar Pattern: Delivers pristine 360-degree acoustic consistency with virtually zero off-axis phase coloration.
- Extraordinary Impulse Response: Lightning-fast transient handling ensures near-perfect time-domain alignment for advanced analysis software like SMAART™, SIM™, MLSSA™, and REW™.
- High SPL Handling: Safely manages up to 140 dB SPL without distortion, making it suitable for close-range speaker testing and high-output acoustic environments.
- Temperature-Compensated Electronics: Built with robust internal circuitry designed to deliver stable, repeatable test results despite environmental fluctuations.
- Individual Calibration & Documentation: Hand-tuned in the USA and shipped with its custom factory frequency calibration chart, with Electronic Calibration Files (ECF) available.
