M30

The M30 is a precision engineered 30kHz omnidirectional measurement microphone 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.

The M30 is part of the M-Series lab-grade audio instruments and can handle any environment, due to its temperature compensated electronics. Mic has a flat frequency response that extends from 3Hz to 30kHz, an exceptionally consistent omnidirectional polar response, 140dB SPL rating without distortion, and no handling noise.

Features:

  • 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
  • Omnidirectional polar pattern
  • Flat frequency response, fast impulse response and exceptional polar characteristics
  • 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: -10 deg C to +40 deg C ( 14 deg. F to 104 deg. F)
  • Storage Temp Range: -20 deg C to +50 deg C ( -4 deg. F to 122 deg. F)
