Description

Earthworks M Series, which includes this M30 30kHz Omnidirectional Measurement microphone, are 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.
