It features a linear free-field frequency response from 3Hz – 23kHz, very low handling noise, uniform polar pattern, and very high SPL handling capabilities.
Re-calibration recommended every five (5) yearsĭesigned and calibrated for measurement tasks, the Earthworks M23 is a pre-polarized condenser microphone directly coupled to a wideband, low output-impedance preamplifier.Each M Series microphone is delivered with its own calibration chart providing its individually measured open-circuit sensitivity and the frequency response curve.
Meets or exceeds ANSI Type 1 and applicable IEC 61094 requirements.Used by SMAART, MLSSA, Spectrafoo, TEF and RTA in addition to acoustic measurement systems manufactured by dbx, DEQX and others.Flat frequency response, fast impulse response and exceptional polar characteristics.Ideally suited for acoustical measurements sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required.Improved version of the SMAARTMIC previously offered by EAW.Earthworks M23 omni measurement microphone in one take: Immune to most temperature and atmospheric fluctuations, the M23 delivers reliable and repeatable results in any environment. It has a flat frequency response that extends from 3Hz to 23kHz, an exceptionally consistent polar response, and 140dB SPL rating without distortion and no handling noise. The M23 is a 23kHz omnidirectional microphone that offers an affordable entry to precision testing. Drawing on his immense design acumen from his days as founder of dbx and creator of innovations such as over-easy compression (still ubiquitous in the studio), Blackmer realized that in order to measure the response of such speakers, his test equipment needed to far surpass the performance on any test microphones available at the time-and thus Earthworks range of measurement microphones were born (which also laid the foundation for all subsequent Earthworks microphones). When David Blackmer founded Earthworks, his goal was to create the best-sounding speakers the world would ever hear. Description Earthworks M23 is an affordable omnidirectional measurement microphone with flat, 3Hz-23kHz frequency response, exceptional polar characteristics and super-fast impulse response
