Earthworks Audio M23 Gen2

While the M23 Gen2 is engineered specifically for acoustic measurement and system calibration, its exceptionally flat frequency response and high SPL handling make it a capable tool for capturing sound sources where absolute transparency and accuracy are the priority. However, it lacks the colored character or proximity effect typically desired for vocal or instrument recording.

The M23 Gen2 is flexible and operates on standard 48V phantom power, which is recommended for optimal performance and maximum SPL handling. It can also function on 12V phantom power, though this will slightly reduce the maximum sound pressure level capacity to 133 dB.

The omnidirectional pattern is essential for measurement because it captures sound equally from all directions, ensuring that your analysis software receives a complete, unbiased picture of the room's acoustic response rather than focusing on a single point.

The M23 Gen2 comes with everything you need for immediate setup, including a storage bag, an MC1 microphone clip, an OMW2 windscreen, an ADP1 adapter, a 5/8" to 3/8" thread adapter, and a calibration chart specific to your unit.

Yes. The M23 Gen2 is built to handle high sound pressure levels, capable of measuring up to 140 dB when powered by 48V phantom power, making it reliable for testing loud PA systems or industrial noise sources without distortion.

The M23 Gen2 offers an impressively wide frequency response of 5 Hz to 35,000 Hz with a tolerance of +/- 1 dB, ensuring that you capture the full spectrum of audio data with high precision.
