IEC 60942 Class 1 Calibrator for standard ½”, 1” and ¼” microphones.
The Rion NC-75 is Rion’s new IEC 60942 Class 1 Acoustic Calibrator.
The NC-75 features an integral reference mic and feedback system which automatically compensates for atmospheric conditions and the load volume of the microphone making ideal not only for Rion microphones/sound level meters but any manufacturer’s microphones as long as they meet the size specifications set out in IEC 61094-4.
The Rion NC-75 can be used with 1/2″ and 1″ microphones and can also support 1/4″ microphones when used with an optional adaptor.
With at least 30 dB(A) of acoustic isolation, the NC-75 can be used in noisy environments and has a battery life in excess of 50 hours.
