JT-MB-CA transformer is designed to couple a nominal 150ohms mic to the 3kohms input impedance typical of transformerless preamps. Both windings are fully balanced and either may be reversed to invert polarity. A 30dB magnetic shield package is standard. Not recommended for mic splitter applications (use JT-MB-C).
