Take the controller, mic adaptor, and splitter
Attach the microphone adaptor to the controller
Attach the splitter to the adaptor
Connect your microphone to one side of the adaptor (My microphone is turtle beach x12s)
Connect the phone to the other side of the adaptor
Download your auto tuning app on your phone (I used the app I Am T-Pain 2.0)
Start the app and start to use it!
Have fun using auto tune on yourself to confuse people!
