It's just like a speaker and you hook it to a separate amp. I'm using one of my sub preouts, running a rca from there to the amp the seller gave me. I could use spare channels on my Monolith too, should I want to since I have the MiniDSP. I think the Mono can do it pretty easily for a nearfield setup. Especially if I... BI AMP! :p\n\nI do have a ground loop tho... I can hear it coming from the 1212 when nothing is playing and I get close to it. Like ear a couple inches away. Sounds higher than 60 hz too. I'm guessing distance and using a connector between 2 rca's isn't helping.\n\nMight try lifting the ground on the Behringer amp to see if that's it?
