Hello Rick and welcome to the Cow Audio Forum
The best way to get audio from a mic into your computer is with a Centrance Micport Pro.
I provides Phantom Power if your mic needs it and uses the USB port on the computer.

The Phantom Power supply powers a small circuit in externally polarized condenser mics that converts the exceedingly high capsule impedance into an impedance that a mic preamp wants to see.
