E1DA 9038S, for example, has a significant DC offset, so the zero point of the signal is not the same as the USB ground. This makes it unsafe to connect to unbalanced devices with adapters, it is intended for headphones, which don't care about a DC offset.
D10 Balanced's DC offset is smaller, according to the specs at most 70 mV, and you are responsible to ensure your system can tolerate that, so that for example your unbalanced input is DC isolated from the ground.
DC doesn't matter. You have a capacitor at input.
