Earthworks M30BX Measurement Microphone (Battery Powered)

SKU: EARTH-M30BX

The 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 wide-band 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. These microphones offer exceptional accuracy for critical recording and room calibration.

Earthworks' M30BX is a cost effective reference microphone, featuring battery operation for remote field use. 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 provides outstanding clarity for recording applications where the goal is to capture the natural sound of a source (such as acoustic guitar), with minimal coloration from the microphone.
