My mixer has loads of outputs (four group outs, four aux, two stereo jacks, two xlr stereo outs, rca outs, monitor outs, headphone jack, etcetera) and they are all balanced output TRS and XLR compatible. I know I can connect my mixer outputs to my dp inputs (a through h), however, I'm not quite sure how I'd be able connect my dp outputs to my mixer inputs using TRS and XLR.
