getting started with the rme adi-2 dac


I am sitting and looking at my new rme adi-2 dac and wondering how to set it up as a dac only. With no volume control and input from a streamer via coax SPDIF and analog rca out to my PL HP integrated.

So I just want a "normal" dac. Any tips for setting it up for best sound quality.
