The Shure a 95U Transformer provides 24 dB of voltage gain and may be used in reverse (high- to low- impedance) and comes with a balanced 3-pin XLR male low-impedance connector. An Amphenol MC1M-type output connector and female phone jack complete this transformer.
The transformer permits use of very long microphone cables with either low- or high-impedance microphones.
The transformer prevents high-frequency loss, level loss, and pickup of noise and hum.
