Hey, all. I thought I would just start this off by saying I don't know if this is in the right category, so correct me if I'm wrong. Anyway, my name is Declan and I've been having some trouble connected my Promedia 2.1 speakers to my Focusrite 6i6. There is one green input that I have going through a 1/4 inch adapter into Line output 1 (pictured below), that connects to my Promedia system. This green cord is the only thing I have going into my Focusrite. When I attempt to play through the monitor, the subwoofer doesn't work, and I only hear what's sounds like half of the sound. For instance, if I put the song "Fall" by "Chon" on, I only hear one of the two guitars and hardly any bass. When I plug my phone directly into the Promedia speakers, the subwoofer works and I hear both guitars. I looked up numerous setup videos and the actual set up guide for the Focusrite and it seems that everybody has two cables coming out of their Focusrite's and into their monitors. Should I have a second cable? Any help is appreciated, thanks, Declan
