Earthworks M23 23kHz Omni Measurement Microphone Clearance Wide Range Of

Earthworks model M23 23kHz Omni Measurement Microphone

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.

Key Features
