EARTHWORKS M23R


The M23R is a factory-sorted M23. The unique thing about this mic is that each M23R has the same frequency response and sensitivity, matched to within +/-0.5dB across the entire operating frequency range.  This allows any M23R mic to act as a matched pair (or triple or quad) with any other M23R mics.  You can build your own matched array of reference mics at your own speed. Simply add more M23Rs whenever you need them. 

Every M23R is delivered with its own printed frequency response chart. A detailed Electronic Calibration File (ECF) is generated for each microphone during final testing. Your microphones individual ECF can be downloaded from the Earthworks website after product registration.

Note: When measuring SPL at concert levels the relatively high sensitivity of Earthworks measurement microphones can overload most input device preamps. If SPL measurement is critical, we recommend that you confirm that your preamp’s max input level meets or exceeds +19 dBu to prevent overload.
