Description
The Earthworks M30 is built for engineers who need trustworthy data, not just sound. As part of the M Series, it’s become a go-to choice for affordable, precise reference measurement work — offering accuracy in both the time domain and frequency response that holds up under scrutiny.
Its small-diaphragm omnidirectional capsule is engineered for a clean, fast impulse response and remains stable across changing temperature and atmospheric conditions, so your measurements stay consistent session after session. Handling noise is virtually eliminated, keeping your data free of artifacts.
- Omnidirectional polar pattern with flat, wideband frequency response
- Fast impulse response and exceptional polar characteristics
- Meets or exceeds ANSI Type 1 and applicable IEC 61094 standards
- Compatible with SMAART™, MLSSA™, Spectrafoo™, TEF™, RTA, and acoustic measurement systems from dbx, DEQX, and others
- Requires 48V phantom power
- Ships with an individual calibration chart showing measured open-circuit sensitivity and frequency response curve
Whether you’re voicing a loudspeaker, tuning a room, troubleshooting a sound system, or performing quality control in production, the M30 gives you a free-field measurement reference you can rely on. It’s a cost-effective way to bring lab-grade accuracy into everyday acoustic work.
