Earthworks M23R Reference Measurement Microphone

Earthworks M23R Reference Measurement Microphone

Precision and Consistency in Every Measurement

The Earthworks M23R Reference Measurement Microphone sets the standard for precision in audio measurements. Each M23R boasts the same frequency response and sensitivity, matched to within +/- 0.5dB across the entire operating range (3Hz to 23kHz). Thanks to Earthworks' proprietary technologies, every measurement microphone undergoes individual tuning and calibration.

Infinitely Flexible Build your custom matched array of reference microphones at your own pace. Expand with more M23Rs whenever you need; they'll match perfectly tomorrow or even a decade from now.

Consistent Results Across Space & Time Equip all your production teams with matching reference mics for consistent results, regardless of their location or when they join. Whether you're conducting multi-mic measurements or adding new teams, rest assured that all reference microphones are perfectly matched.
