This signal analyzing equipment enables us to conduct a simultaneous measurement for frequency response generated from loudspeaker, SPL, impedance, Fo, Ze, THD, Phase, polarity, and Rub&Buzz. High-frequency signal analysis offers even more accurate testing and identification of Rub&Buzz than existing hearing tests. The algorithm of signal analysis applied to this device allows to detect even minute rub & buzz due to its innovative and new method. The 4-stage defect setting enables even more in-depth assessment. The input and output terminals consist of two respectively.
