Hi, I'm a complete newbie when it comes to sound systems of any kind. I was gifted a couple of old speakers and a friend is wanting to rid himself of a Steinberg ur22. I'm wondering if I can connect my pc to the Steinberg and then from the 2 1/4" jack outputs to my speakers? Is that a thing? Is there an adapter I can use to connect a jack to and old speaker wire connection, or am I being silly.[ATTACH=full]1223[/ATTACH] [ATTACH=full]1224[/ATTACH]
