Hi
i have the same problem on my setup (c24 and 192).
I have tried to connect a RME OctamicD on analog input and at the same time on ADAT input, with 1K tone i have 15 db of difference on digital connection vs analog.
why improve the microphone signal to line level and then missing 15db to analog input???
Help???

Losing one side of a balanced line will give the results you are describing. Check your cables(between the C24 and the I/O box) to make sure they are wired to the correct spec(for the DB25 connectors) and verify that you are getting both signal wires(pin 2 hot AND pin 3 cold).
