MAS-8410
Audio Analyzer


This unit is equipped with Audio Analyzer function incorporating Measurement Section. Since this unit succeeded features of model MAK-6630, the measurement system that has configured under MAK-6630 can be utilized.
DC voltage measurement section and 2-channel switchable AC voltage measurement section are incorporated. The AC voltage measurement section incorporates Level measurement, Frequency measurement, Distortion measurement and well as Relative level display functions. FFT shorten the measurement time as it measures level and distortion simultaneously. It is equipped with various filters including 15kHz/20kHz PRE LPF.

For Telephone, PA and Intercom
