EARTHWORKS M23R


The M23R is an omnidirectional measurement microphone with an operating frequency range of 3Hz to 23kHz. 

The unique thing about this mic is that each and every 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.  Or equip your whole production team with mics you know will match, no matter what.  They'll match today, tomorrow, or 10 years from now. 

The M23R is ideally suited for acoustical measurements including loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required.
