Microphone bridging transformer is designed to be driven from a 150ohms microphone source and loaded by the typical 1kohms input impedance of microphone preamplifiers. It can be used with balanced or unbalanced sources and/or loads since both primary and secondary are fully balanced. A 30dB magnetic shield package is standard.
