TimR, you've nailed it pretty much and you've understood it.
It's very simple really. I want EQ control at my feet of my in ear bass tone.
I don't care what the engineer does to it out front. That's his business.
My question was, if I'm pulling a bass signal from one di into another di, will I have a phase issue.
So, the 1st di goes straight to FOH (engineer has control of everything on that channel and i get full band mix back except the bass channel).
The 2nd di then takes the link signal from the 1st di and runs back to a different channel which doesn't go to FOH but does get sent back to me as part of the band mix but, and crucially, I have EQ control at my feet of that bass channel specifically just so I can get a nice bass tone in my ears and have a nice band mix behind it.
Is that any clearer. It's a very simple setup.
Thank god someone gets it
