MIT Mic Transformer, XLR Female LO-Z to 1/4" Male HI-Z

To run low-impedance XLR terminated line(like a pro microphone) into a high-impedance 1/4" phone input (like a guitar amp input), it's often necessary to use a line matching transformer like out MIT-435 or MIT-176. The MIT-129 is for impedance matching of a high impedance 1/4" phone equipped source (like an electric guitar) into a low-impedance (mic-level) XLR type input.
