Description

The Earthworks M50 is a premium-grade 50kHz omnidirectional measurement microphone, expertly crafted for professionals who demand the highest level of accuracy in audio measurement and analysis. With its exceptionally flat frequency response from 3Hz to 50kHz, the M50 offers unparalleled transparency and precision, making it ideal for a wide range of high-end applications including loudspeaker design, acoustic research, ultrasonic/subsonic transducer testing, and PA system alignment.

What sets the M50 apart is its combination of blazing-fast impulse response, linear phase performance, and remarkably low distortion, even at sound pressure levels up to 140dB. This level of detail is critical when capturing transient-rich content or analyzing fine spectral information that contributes to our perception of timbre and texture. Built with temperature-compensated electronics for consistent performance across changing environments, and compatible with top measurement platforms like SMAART™, SIM™, REW™, FuzzMeasure™, and more, the M50 is an indispensable tool for engineers, designers, and researchers alike.

Each unit includes a printed frequency response chart and a downloadable Electronic Calibration File (ECF) for precise, software-integrated measurement calibration. Whether you're developing the next generation of high-end audio systems or conducting sensitive acoustical studies, the M50 delivers reliability, accuracy, and reference-quality performance in a compact, rugged design.
