I'm thinking about connecting my Audio-gd NFB-12 to my PC and use the "DAC out" on the back and connect them to my active bookshelf speakers. Basically just using the NFB-12 as a DAC and not use its amp. Thing is, I don't know what exactly to set for the settings on the NFB-12 to have it work correctly. I know I'll set it to "USB" and I'm guessing the "High" and "Low" gains don't matter. What confuses me is the "HP","Variable", and "Fixed". I know it obviously won't be "HP" since that's for headphones, so do I set it to "Variable" or "Fixed"? I would like to be able to control the volume from the computer rather than reaching out to the NFB-12 or my speakers to change the volume if that makes any difference.
By the way, does the NFB-12 need some sort of sound drivers plugging it into a PC via USB?
Thanks for the help!
