The Earthworks M30 is a very cost effective reference microphone for SMAART, MLSSA, Spectrafoo, TEF & RTA and all "audio band" measurements.
The M Series has become the accepted standard for affordable, reliable reference and measurement microphones that are accurate in the time domain and frequency response. They are remarkably stable with respect to temperature and atmospheric conditions and are optimized for clean, very fast impulse performance providing accurate wideband response with virtually no handling noise.
30kHz flat frequency response
Ideally suited for 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
Improved version of the SMAARTMIC previously offered by EAW
Omnidirectional polar pattern
Flat frequency response, fast impulse response and exceptional polar characteristics
Used by SMAART, MLSSA, Spectrafoo, TEF and RTA in addition to acoustic measurement systems manufactured by dbx, DEQX and others
Meets or exceeds ANSI Type 1 and applicable IEC 61094 requirements
Requires 48V Phantom Power
Each M Series microphone is delivered with its own calibration chart providing its individually measured open-circuit sensitivity and the frequency response curve
