My setup, 16 channel mixer. 6 channels going from TRS outputs to RCA inputs on my Delta 1010LT sound card. The Delta 1010LT allows 6 RCA inputs, 2 XLR (pre amp) inputs, a midi input and a S/PDIF input. The problem is I can record the 6 RCA inputs perfectly fine, sounds great. But the 2 pre amp inputs I can't go through my mixer, that'd be two preamp's on a single mic and distortion. So I connect the mic to the input itself. The preamp doesn't have any kind of adjustment, I've looked in the manual, everywhere. I can adjust the channel level itself, but the level is nothing if you can't adjust the preamp. I am still getting distortion, even if I turn the level down. Is there anything cheap I can buy to put a pad on each of the channel's or possibly anyone know anything about the Delta 1010lt.
