EARTHWORKS M23R [Special order item]

The M23R, a true reference microphone

All units have the same frequency response and sensitivity, tuned to within ±0.5dB across the entire operating frequency range (3Hz to 23kHz).

Earthwoks' most popular microphones, the M=Measurement series, are the de facto standard among professional engineers and acoustic researchers for their ability to accurately capture not only frequency characteristics but also the time domain, enabling precise measurement of audio waveforms. The number on each model directly indicates the upper limit of the frequency range they can support, with the M23 capable of measuring frequencies up to 23 kHz.

It is resistant to temperature and atmospheric changes, has clean and extremely fast impulse performance, and its high stability allows for precise measurements over a wide frequency range. Furthermore, its near-zero handling noise is also an important factor for precise measurements. This microphone can be used not only for sound field measurements, but also for the development, evaluation, and research of acoustic equipment.


Features

23kHz measurement microphone
The M23R is an economy model widely used for measuring room treatments, including the acoustic design of recording studios, and is also widely supported by SMAART users.

Perfect match
Every M23R has the same frequency response and sensitivity, tuned to within ±0.5dB across the entire operating frequency range (3Hz to 23kHz), a proprietary Earthworks technology that allows for individual tuning and calibration of every measurement microphone manufactured.

Infinite flexibility: Since there are no differences in characteristics between individual units, you can safely add M23Rs as needed. You can perform measurements with the same characteristics whether tomorrow or 10 years from now.


Get reliable results anytime, anywhere with this reference microphone that matches your entire production team, ensuring consistent results wherever you are. Whether you're starting a multi-mic measurement or working with a new team, you can rest assured knowing that all your microphones are matched.
