Earthworks M23 Measurement Microphone

Earthworks M23 Measurement Microphone

SKU: EARTH-M23

Earthworks' M Series has become the accepted standard for affordable, reliable reference and measurement microphones. They are optimized to have a neutral, uncolored response, capturing fast transients and accurate frequency response with virtually no handling noise. Stable with respect to temperature and atmospheric conditions, the M Series creates transparent recordings both indoors and outdoors.

The M23 is a cost effective reference microphone for recording, room calibration and acoustic measurements in the "audio band". It has a flat frequency response, fast impulse response and exceptionally uniform polar characteristics.

Because this microphone is so neutral and has a fast transient response, it also provides outstanding clarity for recording applications where the goal is to capture the natural sound of an instrument, with minimal coloration from the microphone.
