If your mixer doesn't have phantom power (some boards mark it as +48V), you would need a special phantom power supply, other than that you hook it up just like any other mic.

If you mixer has the phantom power, you connect your mic then engage the phantom power. Nothing really unique about setting them up, except you would want to get a shock mount adapter if it don't come with one - it isn't a handheld mic, you set it up & leave it alone. Sing anywhere from 6"-12" away. It's going to pick up every little noise so make sure you are isolated as much as possible.
