8.If you plan to use a cable connector, solder the other end of the mic cable to a 3-pin professional audio connector (XLR-type). Solder the cable shield to pin 1, light-colored lead to pin 2, and darker lead to pin 3.

9.If you plan to use a cable connector, con- nect the 3-pin pro audio connector to the input of a phantom power supply. Crown makes a PH-4B phantom power supply (4 channels, AC-powered) and PH-1A phantom power supply (1 channel, battery or AC- adapter powered).

10.Connect the output of the phantom supply to your equipment mic input. Or, if your mic input has phantom power built in, simply connect the mic cable to the mic input.

11.If the mic cable is run in metal conduit,

ground loops might occur that can cause hum. If hum is present after installation, remove the ground-lift jumper (labeled GND LIFT) on the printed-circuit board.
