Hosa MIT-129 1/4" TS to XLR3M Impedance Transformer This adaptor is designed to match 50K output impedance to 200R input impedance. It is ideal for connecting a hi-Z instrument to a microphone input Maximizes signal fidelity when using impedance mismatched gear Minimizes high frequency and level loss caused by signal reflections Eliminates noise and hum caused by an impedance mismatch Connector(s): 1/4 in TS to XLR3M
