Earthworks M30 Omnidirectional High Definition Measurement Microphone

Ideally suited for acoustical measurements including loudspeaker design, system setup and more.

The M30 is a precision-engineered 30kHz omnidirectional measurement microphone ideally suited for acoustical measurements including loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or any application where an accurate, free-field measurement microphone is required. Accuracy, consistency, and reliability have made the Earthworks M30 measurement microphone the first choice of live sound professionals, acousticians, and researchers all over the world for nearly 20 years. Used on countless full-scale concert tours, as well as in scientific research laboratories, tropical rainforests, and rocket testing facilities, the M30 and its M-Series siblings have proven to be lab-grade audio instruments that can handle any environment.
