Earthworks M23R Omni Reference Measurement Microphone

The Earthworks M23R Omni Reference Measurement Mic is matched with all Reference Series Mics within ± 0.5dB of each other in Frequency Response & Sensitivity

The Earthworks Reference Series measurement microphones are a significant offering to the world of acoustic measurements. Historically, measurement microphone manufacturers have only been able to match microphones to within 2 or 3dB of each other.

If you purchased a number of matched microphones and wanted to add more, you would need to send one of your microphones back to the manufacturer to match it to additional new mic(s). Earthworks proprietary technologies have always allowed matching microphones with much tighter tolerances (within 1dB or less).

Each Reference Series measurement microphone is manufactured to within ± 0.5dB of each other in frequency response and sensitivity. This ensures that any microphone in the series will be matched to all others now and forever while also eliminating the need for ECFs (Electronic Calibration Files) in most cases.
