The Shure A95UF is a reversible transformer that matches low-impedance microphones to high-impedance inputs or high-impedance microphones to low-impedance inputs. The transformer permits use of very long microphone cables with either low-impedance or high-impedance microphones. The only requirement is to limit the cable to 4.6 m (15 ft) between the high-impedance end of the transformer and the low-impedance microphone or microphone input. The transformer prevents high-frequency loss, level loss, and objectionable pickup of noise or hum. The A95UF is furnished with a Female XLR professional audio connector on the low-impedance end, and with both a standard 1/4-inch male phone plug and female phone jack adapter for the high-impedance end. Typical applications include connecting a balanced low-impedance microphone to an unbalanced high-impedance input on a mixer or recorder, and connecting a balanced mixer output to an unbalanced high-impedance input on a recorder.
