Description
The Earthworks M23 is engineered for engineers who need trustworthy numbers, not just good-sounding audio. As a member of Earthworks’ M Series, it delivers accurate time-domain and frequency response performance, with the stability to hold up across shifting temperatures and atmospheric conditions. Its fast impulse response and low handling noise make it a dependable tool wherever precise, free-field measurement matters.
- Flat frequency response to 23kHz
- Omnidirectional polar pattern with exceptional consistency
- An improved successor to EAW’s SMAARTMIC
- Compatible with SMAART, MLSSA, Spectrafoo, TEF, RTA, and measurement platforms from dbx, DEQX, and others
- Meets or exceeds ANSI Type 1 and applicable IEC 61094 standards
- Requires 48V phantom power
Suited to acoustical measurement, sound system setup and troubleshooting, and room acoustics work, the M23 is a cost-effective entry point into serious measurement microphones without sacrificing accuracy. Each unit ships with its own individually measured calibration chart documenting open-circuit sensitivity and frequency response curve; an electronic calibration file is also available. Earthworks recommends re-calibration every five years to keep readings dependable over the long haul.
