So the suggestion for someone that isn’t sure which output or input to use is to multi track with LTC then post? Seriously?

OP find the sound person at the gig (beforehand) and tell them what you need. In this case a likely solution if you wanted a mix of what was coming out of the live system would be to come out of the Alt outs on the Qu. Your camera audio inputs and how the operator has the console configured will dictate which adapters you may need to cable it up. I’d suggest either finding a sound person locally to help you or at least running it by the house sound prior to the day of the event. While this is a basic thing for a moderately experienced sound op if your client is expecting at least passable results you’re going to need direct help rather than us randos on the internet.
