Thanks for this Info.. i just got a new one and it helped me. Coming to the overall volume control for the sub out also there is a solution. You can assign any one live control knob to it. 1. Go to menu 2. Live control 3. Knob 1 - click on 1 option 4. Select volume under function 5. Category will be mixer 6. Close the page. 7. At the bottom select which volumes you want to control. Once this is done. The overall volume including the sub outs will be controlled on a single knob.
