Earthworks M30 Measurement Mic

The measurement mic if you’re serious about sound. 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. Unparalleled Audio Results at an Affordable Cost 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. Consistent Measurements in Any Location Immune to most temperature and atmospheric fluctuations, the M30 delivers reliable and repeatable results in any environment.  Precision With Your Favorite Measurement Software The M30 works with any high-quality FFT-based real-time audio system measurement software, like SMAART™, SIM™, REW™, Electroacoustics Toolbox™, FuzzMeasure™ and others, as well as for use in PA system alignment and loudspeaker design. Electronic Calibration File Every M30 is individually hand-tuned and tested and is delivered with its own printed frequency response chart. An Electronic Calibration File (ECF) is generated for each microphone during final testing, and can be downloaded free of charge after product registration. Professional products designed with professionals in mind In audio, our perception of what feels real and natural is incredibly sensitive to resolution in the time domain. In particular, the level of detail present in the initial transient is responsible for much of our sense of content, meaning, and frequency balance. This includes defining attributes like “timbre”, “texture”, and “air”.
