Hi - newbie here! Apologies if this has already been answered somewhere, but as many have observer, searching these forums isn’t exactly easy! 
In a scenario like:
SQ is doing monitors, and has additional SLink card;
Qu is doing FOH;
Inputs and Outputs (mons and mains) are via a Stagebox (AR2412 or cascade of DX168)
Inputs from Stagebox → SQ via SQ-SLink1
SQ Tielines → QU inputs via SQ-SLink2
1: In this setup, how are the stagebox input gains and phantom controlled? Can they be controlled from either console?
2: Inputs go from SQ to Qu via tielines, but what’s the best way to patch the Qu L-R main mix to the stagebox outputs?
Grateful for any wisdom…
1: They can only be controlled from the console to which the stage box is connected.
2: A&H says:
Thanks - that’s what I thought, but I wanted to make sure I wouldn’t be fighting my FOH guy for control of input gains.
Now all we need to do is to find a way to propagate the channel labels from SQ to Qu, and we’ll be good to go. I don’t suppose that’s possible…?
I do think that the approach to strip labelling is oddly weak compared to most other aspects of the SQ, which are generally excellent. There’s no way to connect a proper keyboard AFAICS (though I have a bluetooth keyboard working on the iPad, which works), and there’s only six characters to play with for the labels.
