how hook up bluesound node 2 to external dac


I just received my bluesound node 2i and have a couple of questions. How do I connect it to my external dac and can it use USB cable or does it need to be toslink or coaxial.  I know several of you do this your help would be appreciated.

Since all outputs are active on the Node you can experiment between optical and coax. I happened to prefer coax with my system.
I've gotten most of my questions answered.  I am using an android tablet with blueos, my question is it better to use a laptop for the app. Tell me what your experiences are. 

Thanks

If you have a laptop why not just try it yourself. It’s not going to make a bit of difference SQ wise. Usability might be better, but at the expense of convenience.
