Earthworks M Series measurement microphones have become the accepted standard for reliable measurement and reference. They are accurate in the time and frequency domain and have exceptionally uniform polar response. They feature flat free-field frequency response, fast impulse response, and are remarkably stable with respect to temperature changes, meeting or exceeding Type 1 specifications.

Measurement for Professionals
The M30 is one of the most respected, accurate, and reliable measurement microphones on the market. Consultants and Acousticians throughout the world rely on the M30 in performing their measurements and acoustical analysis. In addition, they have great respect for the near-perfect polar response of this microphone. The M30 provides an impressive frequency response of 3Hz to 30kHz, near-perfect polar response and it will handle 140dB SPL. For those looking for an extremely accurate and reliable measurement microphone, the Earthworks M30 is it.

Power Requirements
The Earthworks line of measurement microphones require standard 24-48V phantom power and up to 10mA of current. 10mA of current is required to supply Earthworks high-current, bipolar Class-A amplifier within the microphone that is made with all discrete components, with no capacitors in the signal path providing excellent phase response. This also allows the microphone(s) to feed long signal lines up to 300 feet and maintain the full frequency response of the microphone at the other end of the line, without any loss in high-frequencies.

Rugged Construction
The M30 is robust and can be used in a wide variety of environments from the most elegant of research laboratories to making measurements in the outdoors and tropics. In making acoustic measurements, the M30 will be your most trusted, accurate and reliable measurement instrument.
