30KHZ MEASUREMENT MICROPHONE

M30

Hyper accurate. Reliable results. Every single time.

The measurement mic if you’re serious about sound.

Used on countless full-scale concert tours, as well as in scientific research laboratories, tropical rainforests, and rocket testing facilities, the M30 has proven to be a lab-grade audio instrument that can handle any environment.

Unparalleled Audio Results at an Affordable Cost

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.

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.

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
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.
