Description

M2211 is a calibrated, 1/2" omni-directional measurement microphone with class 1 frequency response. It runs from 48V Phantom power and contains an electronic data sheet. It shows excellent linearity over a wide dynamic range from 21 dBSPL up to 144 dBSPL.

The measurement microphones are optimized for a flat, free-field response in the frequency range 5 Hz - 20 kHz. Models for acoustic measurements of up to 155 dB are available.

All microphones are omni-directional and 48V phantom powered. The XL2 Analyzer microphones include an electronic data sheet. The Automated Sensor Detection (ASD) of the XL2 automatically reads this data sheet, and recognizes the microphone model, sensitivity and calibration data. This ensures accurate measurement results.

The microphone bodies contain the preamplifier. They combine high dynamic range and wide frequency range with low noise. These measurement microphones connect via the ASD Cable to the XL2 Audio and Acoustic Analyzer, e.g. for measurements at remote locations or to reduce acoustic reflections.

Features:

  • Omni-directional, free-field microphone
  • Phantom power 48 VDC
  • Electronic data sheet installed
  • Frequency range 5 Hz - 20 kHz
  • Individual frequency response available as Excel-data
  • Optional calibration certificate
  • M2230, M2211, M2215 are formed by a combination of preamplifier MA220 and a dedicated microphone capsule

Applications:

  • Noise Measurements
  • Cinema Calibration
  • PA Rental
