Microphone input transformer with its 4.1kohms secondary source impedance, this transformer not only optimizes noise performance of many IC or discrete amplifiers but also offers excellent CMRR as well. The primary is fully balanced and its leads may be reversed to invert polarity, if required. A 30dB magnetic shield package is standard.
