jw, The music comes in through your internet connection. For most people that is wifi these days. You connect a streamer to your wifi modem (router) wirelessly (wifi) or wired (ethernet cable, Cat 6 or 7 whatever they’re up to today).
You then send digital out from your streamer to your DAC over a digital interconnect, or if your streamer is a streamer/DAC, send it to your preamp from the analog out jacks with ordinary analog interconnects. The Bluesound Node 2i is a streamer/DAC.
Then to control your streamer you download an app (usually free) to your phone or tablet. The Node 2i uses the BluOs app which is very easy to use and functions really well. It is all pretty simple and you can get help if you need it
