Earthworks M30 Omnidirectional Measurement Microphone

Earthworks M30 30kHz omnidirectional measurement microphone is 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.

It has a flat frequency response that extends from 5Hz to 30kHz, an exceptionally consistent omnidirectional polar response, 138dB SPL rating without distortion and no handling noise. With temperature compensated electronics, the M30 was built to deliver repeatable results no matter what the environment.
