You're done
When you're done, just unplug the mic. Your receiver should be setup properly for surround sound in your room.
If you're at all technically inclined you might want to forgo the auto setup and tackle manual speaker setup. It's not all that difficult, but you should use a sound pressure level meter, such as a
Radio Shack 33-4050. You'll probably do a better job yourself than the auto setup.
