The measurement mic if you’re serious about sound.

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. 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.

The measurement mic if you’re serious about sound.

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. 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.

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.

The M30’s audio performance is unparalleled. It has a flat frequency response that extends from 3Hz to 30kHz, an exceptionally consistent omnidirectional polar response, 140dB 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.

Extremely fast impulse response and linear phase response make the M30 ideal for use with high-quality FFT-based real-time audio system measurement software like SMAART™, SIM™, REW™, Electroacoustics Toolbox™, FuzzMeasure™ and others, as well as for use in PA system alignment and loudspeaker design.

Every M30 is individually hand-tuned and tested and is delivered with its own printed frequency response chart. An Electronic Calibration File (ECF) is generated for each microphone during final testing, and can be downloaded free of charge after product registration.

 Suffice to say that the M30 is the most durably built measurement mic I’ve run across in 30-plus years of doing sound.

The accuracy of the Earthworks M30 microphone is stunning. I know that when the system is tuned using this microphone the results will be pure audio bliss.

The Earthworks M30 measurement mic is the first piece of gear I grab for when I’m ready to tune my P.A. system, I know its frequency response is very accurate and will tell me exactly what’s happening in the room

Rick Camp, FOH ENGINEER

Every show I’ve mixed for Umphrey’s McGee is available for download. That requires accurate tuning for my mix to translate to the recording. The M30 is the most accurate way I can measure that.

Chris Mitchell, FOH ENGINEER

I take tuning as seriously as I do mixing. If there’s anything I own that I can honestly say makes it to every gig, its my Earthworks M30.
