Open Setup>IO and select the INPUT tab. Delete any inputs that are listed and then hit the DEFAULT button. That SHOULD populate 18 inputs in 9 stereo pairs(each stereo pair has 2 mono sub-paths). Its worth spending time to learn how(and why) to modify and customize the IO settings. Next, given you have the Trident, I would take a direct ouit of each Trident strip and feed the 8 TRS inputs on the 002. If the Trident does not have direct outputs on each channel, then I would use unbalanced cables from the insert jacks(only pushed in 1 click). I also second the purchase of an 8 channel lightpipe preamp in the near future
