Earthworks M30BX Battery Powered Omni Measurement Microphone

The Earthworks M30BX is a measurement mic that features an ultra wide frequency response of 9Hz to 30kHz is flat throughout the entire spectrum and results in accurate room calibration using Smaart, MLSSA, SIMM and TEF based systems. The small element yields an omni-directional pattern resulting in a wide pick up area at the front and sides of the microphone capsule.

The M30BX’s audio performance is unparalleled. It has a flat frequency response that extends from 9Hz to 30kHz, an exceptionally consistent omnidirectional polar response, 140dB SPL rating without distortion and no handling noise. With temperature compensated electronics the M30BX was built to deliver repeatable results no matter what the environment.

Extremely fast impulse response and linear phase response make the M30BX ideal for use with high-quality FFT-based real-time audio system measurement software like SMAART™, SIM™, REW™, Electroacoustics Toolbox™, FuzzMeasure™ and others, as well as for use in PA system alignment and loudspeaker design.

Earthworks M30BX Features

  • Microphone body opens for replaceable battery access, with a battery life of 300 hours
  • Works with RTA apps by using iPad / iPhone to TRRS to XLR mic cable
  • 30kHz flat frequency response
  • 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
