M23, M30, M30BX, M50

With the purchase of any Earthworks measurement microphone beginning on July 1, 2012, customers will receive an electronic calibration file, mic clip, ½ inch calibrator adapter and case. Customers will receive their ECF via email after registering their Measurement Series microphone on the Earthworks website.

Together with the provided sensitivity of your individual microphone, the ECF can be used to calibrate your specific microphone to your measurement software or system.

Hand built, tuned and tested in the Earthworks facility in Milford, NH, the Measurement Series includes models with upper frequency responses of 23kHz, 30kHz and 50kHz. Each microphone’s capsule is hand tested and matched to its circuitry to provide the most accurate responses.

MAP pricing: M23 – $459; M30 – $649; M30BX – $799; M50 – $1299
