Description
The Earthworks M30 belongs to the M Series line that’s become a go-to choice for engineers who need reference-grade measurement without reference-grade pricing. It’s built to stay accurate in both the frequency and time domains, holding steady through temperature swings and changing atmospheric conditions rather than drifting when you need it most.
- Cost-effective entry into serious acoustical measurement
- Suited to loudspeaker design and QC, sound system alignment and troubleshooting, room acoustics analysis, and any job calling for a true free-field measurement mic
- Omnidirectional polar pattern for consistent, direction-independent capture
- Flat frequency response paired with a fast impulse response and clean polar behavior, so transients arrive undistorted
- Compatible with SMAART, MLSSA, Spectrafoo, TEF, and RTA workflows, plus measurement systems from dbx, DEQX, and other manufacturers
- Meets or exceeds ANSI Type 1 and applicable IEC 61094 standards
- Runs on 48V phantom power
- Ships with its own calibration chart, documenting the individual mic’s open-circuit sensitivity and frequency response curve
Because handling noise is virtually nonexistent and the impulse response is fast and clean, the M30 gives you measurement data you can actually trust — whether you’re tuning a room, verifying a loudspeaker design, or diagnosing a system in the field. It’s a practical tool for anyone who needs accurate wideband readings without guesswork.
