Have you been to https://www.allen-heath.com/ahproducts/qu-16/#tab3 and scrolled down to the “tutorials” section? What is it about the sends/groups you don’t understand? Is it a pre/post, assign/un-assign thing, or is it a “should I use groups or DCAs” thing? Are any of those terms familiar to you?
Are you familiar with analogue systems and you’re just having trouble adjusting to digital?
Is it that you know what you want the mix to sound like, but don’t know how to go about achieving it on the Qu series? Which Qu do you have; 16, 24, 32 or Pac?
Is it that the Qu series looks like an intimidating piece of technology, and as someone who is into computers and technology you’ve been nominated as the sound man, but you don’t really know what you should be aiming for in terms of what the mix should sound like?
Sorry if any of that sounded condescending, I don’t mean it to be, but I’m sure many of us on here could write essays explaining mixing FOH vs mons, when to use pre or post fade sends, when to use groups or DCAs (or both) and how things should be routed/processed etc, but we could save a whole lot of time if you ask specific questions. I know you did ask a specific question in the thread title and first sentence of the OP, and there are videos out there, but if you were to ask a specific question such as “when should I use a pre-fade send” or “how do I get reverb in the monitors,” then we can tailor our answers to suit.
