Brand New Products,15 Years Warranty, and 2 to 3 Days Free Shipping (Authorized Dealer)

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.

  • 23kHz flat frequency response

  • Cost effective measurement microphone

  • Improved version of the SMAARTMIC™ previously offered by EAW

  • Ideally suited for acoustical measurements sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required

  • 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

  • Meets or exceeds ANSI Type 1 and applicable IEC 61094 requirements

  • Requires 48V Phantom Power

  • Each M Series microphone is delivered with its own calibration chart providing its individually measured open-circuit sensitivity and the frequency response curve

  • Electronic Calibration File available

  • Operating Temp Range: -20 deg C to +60 deg C ( -4 deg. F to 140 deg. F)

  • Storage Temp Range: -20 deg C to +50 deg C ( -4 deg. F to 122 deg. F)

  • Humidity: Up to 90%

  • Re-calibration recommended every five (5) years
