Earthworks has become the accepted standard for affordable, reliable reference and measurement microphones. These microphones are accurate in the time domain and frequency response. Earthworks measurement microphones are optimized for clean, very fast impulse performance to provide accurate wideband response. They have virtually no handling noise and are remarkably stable with respect to temperature and atmospheric conditions. Our M Series measurement microphones are used by SMAART™, MLSSA™, Spectrafoo™, TEF™ and RTA in addition to acoustic measurement systems manufactured by dbx, DEQX and others. All models are available in matched pairs.
Omni - 9Hz to 30kHz. Designed to work with laptop computers, our battery operated version of the M30 has a built-in switch which provides +6db gain when needed.
- Microphone body opens for replaceable battery access, with a battery life of 300 hours
- Works with RTA apps by using iPad / iPhone to TRRS to XLR mic cable
- 30kHz flat frequency response
- Ideally suited for on-location acoustical measurements including loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required and portabil
