Forgive (and feel free to correct) any newbie misunderstandings:
I have the ICA4+ and am currently running the main outs of my mixer into line inputs 3 and 4 on the ICA4+. Can I route the mixers sub outs to the mic inputs 1 and 2 on the ICA4+ if I run them through a DI box to increase the functionality?
I've spent a while looking at this and as far as I can tell the only issue would be additional noise from attenuating then amplifying the signal again. If this works or there are better ways to get 4 line inputs on the ICA4+ please share!
