    Description

    Go beyond matched pairs, quads, and octets. The M23R is infinitely matched.

    Features:

    • Infinitely Matched
      • A true Reference Microphone. Each and every M23R has the same frequency response and sensitivity - matched to within +/- 0.5dB across the entire operating frequency range (3Hz to 23kHz).
      • This is made possible by proprietary Earthworks technologies which allow individual tuning and calibration of every measurement microphone produced.
    • Infinitely Flexible
      • A Matched Array That Grows With You
        • Build your own matched array of reference microphones at your own speed. Simply add more M23Rs whenever you need them. They’ll match tomorrow or ten years from now.
      • Consistent Results Across Space and Time
        • Equip all of your production teams with matching reference mics and get consistent results no matter where they are.
        • Start doing multi-mic measurements or equip new teams at any time with confidence that all of their reference microphones match.
        • Eliminate a common source of error - no ECF needed - the M23R is already flat. It's the definition of flat.
