The Performance Plus inline transformer connects a low-impedance microphone with a male XLR plug or guitar cable to a 1/4" high-impedance amplifier or mixer input jack. The MCT-1 can be used to convert the low-impedance signal (Lo-Z) to a high-impedance (Hi-Z) device. It's a great device if you want to use your guitar amp for vocals or want to mic an instrument with a guitar or bass amplifier that has only standard 1/4" phone input jacks. Also great for emergency situations if your PA fails and you need to use your guitar amp for backup.
