Omnidirectional Measurement Microphone - 9Hz to 23kHz

The New Standard in Audio Measurement.

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.
