Got it. Tried to hook it up but so far no sound.
I assume the cable from my Surface Pro, running BIAB, goes into input 1 with a 1/4” phono jack, which I assume has to be stereo. (?)
Then my QSC speaker is hooked up to the two line outputs using separate mono 1/4” phono jacks adapted to RCA plugs.
If so, I need to buy the right connectors.
Please let me know if I’m not understanding this correctly. Thanks.
