Microphone bridging transformer is designed for drive from a 150ohms microphone source and for each secondary to be loaded by the 1kohms input impedance typical of microphone preamplifiers. A pair can be used to make a passive matrix when using the M-S stereo microphone technique. A 30dB magnetic shield package is standard.
