Martin Wollatz's post in DC-Coupling possible on MCC172 ? was marked as the answer
I bought an MCC172 and looked at the input circuitry. As I suspected, there is a high pass built in, but it is even equipped with jumpers to bypass the high pass capacitor. The component values, even if they are measured within the circuit, result almost exactly in the cutoff frequency specified in the data sheet. For DC coupling, simply close the jumper (circled in green).
