OK so I'm having a ground loop problem with my studio monitors. I'm kinda new to the studio but I'm wondering if a DI box would help. My current setup: pc -- m-audio fast track -- power amp -- ns-10's. This puts out a very silent white noise with amp set to lift and a loud buzz with amp set to ground. I am just looking at cheap passive di boxes to put in between the interface and the amp. Will this help the buzzing?
