MC3122
Introduction
MC3122 is a classical Plug-N-Play 2-channel USB data acquisition hardware with two ICCP input channels and two output channels. It is developed for the acoustic measurement in laboratory and field applications. With BSWA VA-Lab software, MC3122 can be used in environmental noise, architectural acoustics, audio test, Impedance testing and sound quality evaluation. MC3122 is developed based on he sound card technology. Each input channel has ICCP power and a gain of X0.1, X1, X10.
