The M23 is a precision engineered 23kHz omnidirectional measurement microphone ideally suited for acoustical measurements including loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required.
Unparalleled Audio Results at an Affordable Cost
A flat frequency response that extends from 3Hz to 23kHz, 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 M23 delivers reliable and repeatable results in any environment.
Precision With Your Favorite Measurement Software
The M23 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 M23 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.
Earthworks was formed by David Blackmer, the inventor of dbx, to realize his vision of upgrading the entire audio chain to a new standard of sonic realism. David's goal of creating high definition tools with which to capture the sound and experience of "being there" is based upon a strong evidence that there is more to human hearing than the range of frequencies which can be heard as tones. We are convinced that audio equipment with extended frequency response and faster, cleaner time domain performance will yield more life-like results. Traditional audio methadology appears to be based on working around the limitations, imperfections, and personality quirks of the equipment, and calling the ones you like "assets". WE believe that any part of the audio chain can be improved to the point where the standard is so high that any product meeting it will be indistinguishable from any other product meeting the same standard, and that an audio system built to such standard can achieve sonic reality. This standard, for electronic equipment, is met by our Zero Distortion Technology. We support the concept of recording acoustic events accurately enough to capture the sound as it happened in the room. This approah allows you to make sonic coloration and texture choices later, when you can consider them carefully and still have recourse. Life-like accuracy is the best starting point for whatever unique coloration you may wish to add.
