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.
