The Earthworks M30 Matched Pair HD Measurement Microphones is a matched pair of Earthworks M30 omnidirectional microphones, that comes in a cherry wood box. 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.
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. Used by SMAART, MLSSA, Spectrafoo, TEF and RTA in addition to acoustic measurement systems manufactured by dbx, DEQX and others. Each M Series microphone is delivered with its own calibration chart providing its individually measured open-circuit sensitivity and the frequency response curve.
