The Earthworks M30 from is a cost effective measurement microphone intended for large and small room calibration. A flat frequency response that extends from 3Hz to 30kHz, an exceptionally consistent omnidirectional polar response, 140dB SPL rating without distortion and no handling noise.

Used on countless full-scale concert tours, as well as in scientific research laboratories, tropical rainforests, and rocket testing facilities, the M30 has proven to be a lab-grade audio instrument that can handle any environment.

The small element yields an omnidirectional pattern resulting in a wide pick up area at the front and sides of the microphone capsule.

Key Features:

• The miniature element provides an accurate omnidirectional pattern with an even coherent response at the direct and off-axis sections of the microphone capsule.
• The wide, linear frequency response accurately captures audio signal and reproduces the slightest nuance with great detail.
• The uncolored, flat signal results in accurate room calibration for indoor and outdoor application.
• Includes microphone clip and calibration adapter
