Earthworks M30BX Battery Powered Omni Measurement Microphone

The Earthworks M30BX is a battery powered omni measurement microphone with a 30kHz flat frequency response and is remarkably stable with respect to temperature and atmospheric conditions.

The M Series has become the accepted standard for affordable, reliable reference and measurement microphones that are accurate in the time domain and frequency response. They are remarkably stable with respect to temperature and atmospheric conditions and are optimized for clean, very fast impulse performance providing accurate wideband response with virtually no handling noise.

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 on-location 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 and portability is important or a power source is not readily available
  • Improved version of the SMAARTMIC™ previously offered by EAW
  • Omnidirectional polar pattern
  • Flat frequency response, fast impulse response and exceptional polar characteristics
  • Used by SMAART™, MLSSA™, Spectrafoo™, TEF™ and RTA in addition to acoustic measurement systems manufactured by dbx, DEQX and others
