Shure A85F Transformer; Low Z, Female XLR to High Z 1/4 Phone Plug
The Shure A85F is a low-to-high impedance microphone-matching transformer used to connect a balanced low-impedance microphone output to an unbalanced high impedance input on a mixer/recorder.
The Shure A85F is a low- to high-impedance microphone-matching transformer that provides 24 dB of signal increase gain. It has balanced female XLR and unbalanced high impedance male 1/4'' phone plug connectors, and may be used in reverse. The A85F is typically used to connect a balanced low-impedance microphone output to an unbalanced high impedance input on a mixer or recorder.
NOTE: Not for connection to the balanced line-level output of a mixer.
