1.) Turn the power switch to "off".
2.) Push "in" both of the FX encoder knobs and hold it them down.
3.) Power up the unit while holding the FX knobs pushed in.
4.) Lights will flash on the board. Let go of the knobs. Then push them in again. Let go.
5.) Push them in once again. Both displays will show "C".
6.) Turn off the mixer and power it up once more. The reset is complete.
