Line inputs on Focusrite interfaces, both standard and combi, go through a small section of the preamp circuit. Due to the transparent nature of our preamps, however, this does not colour the signal.
There is some attenuation and gain available on the line signal, which may benefit users if they are using a unit that sends a very hot or not hot enough signal for their liking.
Unity gain may vary on different models of interface and can be found if needed by sending a Signal Generator from one of the outputs to one of the inputs via a TRS connector and adjusting the Gain Knob until they match in your DAW.
