Whats up guys, I searched on the forums for this but couldn't find exactly what I was looking for... I am currently set up using 2 KRK G2 5's using balanced TRS to *stereo* rca's. The thing is, I'm plugged into an M-audio fastrack, which only has the left and right mono rca inputs. my question is: since i am only using one rca input per cable for each speaker (the red for the left speaker - so the white right rca is just hanging off my desk) and the vice versa for the right speaker, what is causing feedback? Is it because there is one rca input per speaker not being used and causing interference? In that case what could i do to cover them? Thanks and sorry for the long post, just had to make sure you guys got the details. Cheers!
