PHYSICAL DIAGRAM
Immune to most temperature and atmospheric fluctuations, the M23 delivers reliable and repeatable results in any environment.
Consistent Measurements in Any Location
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.
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”. Earthworks’ blazingly fast technology ensures that every performance sounds like life
