How do I set up Symphony I/O for 5.1 or 7.1 surround monitoring?

1. Open Maestro 2 and go to the output tab
2. Scroll to the right and under the main output selection (under the encoder knob), select "5.1" or "7.1"
3. Now the software output encoder knob and the front-panel encoder knob will control multiple outputs for surround sound monitoring.
