NC-74

Sound Calibrator

 

The Rion NC-74 Sound calibrator generates a constant sound pressure of 94 dB at 1kHz.

The Rion NC-74 is designed to be a compact and lightweight unit which requires no atmospheric pressure compensation.

This is done by incorporating a sensor which detects the atmospheric pressure which is in turn detected by the CPU which controls the signal amplitude. This eliminates the need for any pressure compensation.

The Rion NC-74 Sound Calibrator is suitable for 1” and ½“ microphones

Rion NC-74 Sound Calibrator complies with the IEC 60942:2003(JIS C 1515:2004) Class LS/C

Features:

  • Allows for calibration with accuracy of + 0.3 dB
  • Usable in wide temperature and humidity range.
  • Usable as a standard sound source in laboratories or as a calibration sound source for sound level meters on site.
