Description
When you’re tuning a PA or verifying a loudspeaker’s true behavior, you need a microphone that gets out of the way and tells the truth. The Earthworks M30 is a small-diaphragm omnidirectional measurement mic engineered for exactly that — accurate in both frequency response and time domain, with a fast, clean impulse response and virtually no self-noise from handling.
It’s built to stay consistent no matter where the gig takes you, holding steady across temperature swings and changing atmospheric conditions so your readings stay trustworthy from soundcheck to load-out. That reliability makes it a natural fit for system engineers doing house tuning, loudspeaker R&D, room acoustics analysis, or general troubleshooting where a true free-field reference is non-negotiable.
- Omnidirectional polar pattern with exceptional off-axis consistency
- Flat, wideband frequency response paired with fast impulse performance
- Compatible with SMAART, MLSSA, Spectrafoo, TEF, RTA, and measurement platforms from dbx, DEQX, and others
- Meets or exceeds ANSI Type 1 and applicable IEC 61094 standards
- Requires 48V phantom power
Every M30 ships with its own individually measured calibration chart, documenting open-circuit sensitivity and frequency response — so what you see on your analyzer reflects the actual capsule in your hand, not a generic spec sheet. For techs building or scaling a rig where precise, repeatable measurement is part of the workflow, that per-unit calibration is what separates a reference mic from a guess.
