I take the line out from my Kern IP-777 and run it into a channel of my RME Multiface when recording. I am having difficulty getting enough signal to my software. I have the Multiface inputs set at the default (+4), and am wondering if my experience is unusual. I absolutely cannot get enough signal by cranking both the input gain and line out to push the input into the red. Before I open up the Multiface and switch an input to -10, I'd like to know if low line-out levels are typical of the Kern.
