Thanks for the quick reply! I tried pulling the line transformer and now I definitely need a new one. Not easy to get off the board in one piece. Anyway, it has to be the transformer so I don't think there were any hope for it even without me prying it off. Will order a new one asap and will report back.

Thanks again!

So, I got a new line input transformer and installed it. Now I get some sound, but what I'm getting is some 30-35 dB quieter than it is going out from my converters. I also see when running a white noise signal generator out from my converters that the low end rolls off quite a bit steeper than the digital signal I'm sending out from my converters. I'm a bit stumped for where to go with my troubleshooting. Does anyone have any tips? I'm getting the same frequency plot when using the mic input, so I'm guessing the problem lies elsewhere than the line input transformer, maybe? Hmmmm.

(In the photo I've compensated for the level loss by using the trim plugin in Pro Tools)

First,  use pink noise and not white noise. There is a big difference.

Second, try injecting signal after the transformer and see if you get similar results. If the mic preamp is working then number of possibilities for the issue are extremely limited. Inject signal after the transformer and see what happens.

Thanks!
