Most wired microphones will have a male XLR connector on the end of its cable. As a result, you will need
to make a XLR to Phoenix converter cable. Connect the Positive conductor of the Vortex device to Pin 2 of
the XLR connector, the Negative conductor of the Vortex device to Pin 3 of the XLR connector, and the
Shield of the Vortex device to the Pin 1 of the XLR connector. Refer to Cable Drawing 1 in the Vortex Input
Wiring section of the Appendix.
