Earthworks M30 G2 High Definition Measurement Microphone

Earthworks M30 G2 - Precision in Affordable Measurement

The Gold Standard in Acoustic Precision Since 1995

The Earthworks M30 G2 is the industry’s most trusted 30 kHz reference measurement microphone, designed for precision acoustic analysis, system calibration, and environmental measurement. With a flat frequency response from 5 Hz to 30 kHz (±1 dB), exceptionally low distortion, and a textbook omnidirectional pattern, the M30 G2 delivers the reference-grade accuracy that professional engineers and acousticians demand.

Built upon the legacy of the original M30—used worldwide in studios, research facilities, and live sound environments—the second-generation M30 G2 introduces refined circuitry with reduced phantom power consumption, greater SPL handling, and broader interface compatibility. Every detail of this microphone is engineered to ensure consistent, repeatable, and precise results in any acoustic measurement scenario.

Unmatched Measurement Accuracy

The M30 G2 captures sound with uncompromising fidelity. Its 5 Hz to 30 kHz flat response ensures that every nuance of your acoustic environment is reproduced with exacting precision. Each microphone is individually calibrated to Earthworks’ exacting standards, maintaining linearity, phase accuracy, and a true omnidirectional polar response—even under high SPL conditions up to 140 dB.

Improved Power Efficiency and Interface Compatibility

Engineered for modern workflows, the M30 G2 features Earthworks’ lowest-ever phantom power consumption at just 7.2 mA, maximizing battery life when used with wireless measurement systems and ensuring stable performance with multi-mic audio interfaces. Its optimized 1 kHz sensitivity ensures seamless integration across a wide range of input devices and measurement platforms, maintaining clean, accurate readings in every setup.

Precision Engineering and Rugged Design

The M30 G2’s body is crafted from stainless steel, providing durability for field use while maintaining mechanical and acoustic stability. Its balanced XLR output ensures low-noise connectivity, while Earthworks’ time-coherent design preserves phase accuracy for reliable time and frequency-domain measurements. Designed, tuned, and assembled in the USA, the M30 G2 delivers uncompromising performance session after session.
