Earthworks M23 G2 Measurement Microphone

Earthworks M23 G2 - Acoustic Measurement Microphone

The Earthworks M23 G2 is a high-precision reference microphone built for audio professionals who need reliable, accurate, and consistent measurement data. Whether you're tuning PA systems, measuring room acoustics, designing loudspeakers, or collecting environmental data, the M23 G2 delivers true-to-source results with minimal coloration and excellent time-domain performance.

This second-generation model improves on the original with lower current draw, better interface compatibility, and a more compact, travel-ready form factor. Earthworks also includes all the essentials in the box, like a custom calibration chart, windscreen, and rugged storage case.

What’s New in Gen-2

• Lower phantom power draw: 7.2 mA at 48 V extends battery life and supports more mics per interface.

• Reduced sensitivity: Now −40 dBV/Pa for better headroom with interfaces that can’t handle hot inputs.

• Shorter and lighter: Over 1.5 inches shorter than the original, making placement and storage easier.

• Included accessories: Comes with an OMW2 windscreen, MC1 clip, calibrator adapter, and case.

Applications

• Live sound: PA system tuning, delay and phase alignment, SPL monitoring.

• Studio and post-production: Control room analysis, multichannel speaker setup, room mode diagnosis.

• Loudspeaker R&D: Frequency and phase response, impulse response, distortion, and production QC.

• Hi-fi and car audio: System tuning, acoustic measurement, listening space optimization.

• Scientific and industrial: Ultrasonic and infrasonic capture, sound source localization, product noise profiling.
