Earthwork M23 Measurement Microphone
Omnidirectional measurement microphone
The M Series has become the accepted standard for affordable, reliable reference and measurement microphones that are accurate in the time domain and frequency response. They are remarkably stable with respect to temperature and atmospheric conditions and are optimized for clean, very fast impulse performance providing accurate wideband response with virtually no handling noise.
Calibration curve files for Earthworks® measurement microphonesCalibration files are available for every Earthworks measurement microphone at an extra charge. These files can be used to import the microphone’s amplitude frequency response directly into your measurement system. They are in text format, with frequency in Hz in the first column, and response values in dB in the second. Calibration files are available for almost every Earthworks microphone, including microphones purchased previously. Electronic calibration files will be sent to the purchaser via an email attachment.
- Cost effective measurement microphone
- Improved version of the SMAARTMIC™ previously offered by EAW
- Ideally suited for acoustical measurements sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required
- Omnidirectional polar pattern
- Flat frequency response, fast impulse response and exceptional polar characteristics
- Used by SMAART™, MLSSA™, Spectrafoo™, TEF™ and RTA in addition to acoustic measurement systems manufactured by dbx, DEQX and others
- Meets or exceeds ANSI Type 1 and applicable IEC 61094 requirements
- Requires 48V Phantom Power
- Each M Series microphone is delivered with its own calibration chart providing its individually measured open-circuit sensitivity and the frequency response curve
