Connect your mixer to the AC mains power source (power outlet) with the supplied

the mixer; then, plug the other end of the cord set to the AC mains. When properly
connected to a live power source, the power ring should illuminate with a green
color.

feature. Do not attempt to disable this ground connection by using an adapter or
other methods.

1. Turn down the level of your audio source.
