Brand
Earthworks Audio
Looking for absolute precision and laboratory-grade reference performance for audio system tuning and room analysis? The Earthworks M30 is an industry-standard 30kHz omnidirectional measurement microphone engineered to deliver accurate acoustic data across live sound alignment, installed audio, loudspeaker design, and research applications.
Achieve absolute acoustic precision and laboratory-grade data integrity with the Earthworks M30 30kHz Omnidirectional Measurement Microphone. Designed for critical acoustical analysis, loudspeaker design, room correction, and live sound system tuning, this high-definition free-field condenser microphone delivers an ultra-wide, flat frequency response spanning from 3Hz all the way up to 30kHz.
Why Choose the Earthworks M30 Measurement Microphone?
Acoustical testing and real-time audio analysis demand microphones that introduce zero coloration, phase anomalies, or distortion. The Earthworks M30 sets the industry standard by combining a very small, highly accurate omnidirectional element with a robust stainless steel body. It provides uniform 360-degree pickup consistency and exceptional stability across changing environments, ensuring your measurement software captures the true, unadulterated behavior of any space or sound reinforcement system.
Key Performance Features
- Ultra-Wide Frequency Response: Delivers a smooth, flat response spanning from 3Hz up to 30kHz (+1/-3 dB), capturing deep sub-bass characteristics and high-frequency air with total accuracy.
- True Omnidirectional Directivity: Flawless 360-degree pickup consistency ensures accurate sound pressure level capture regardless of microphone orientation.
- Lightning-Fast Impulse & Linear Phase Response: Swiftly tracks rapid acoustic transients, making it exceptionally well-suited for FFT-based real-time analysis software like SMAART, SIM, and REW.
- High SPL Handling: Safely manages up to 140 dB SPL without distortion, allowing direct measurement right in front of high-output concert line arrays or loud test environments.
- Rugged Stainless Steel Construction: Precision-machined from solid stainless steel to endure the daily rigors of field engineering, laboratory testing, and touring.
