I recently bought a pair of KRK Rokit 5 G3 speakers. Its a pretty big upgrade from my previous speakers. Currently, I have them connected using a RCA to 3.5mm cable. When I have it connected to my phone, it sounds great. But when I try to connect it to my desktop, there is this horrible hiss sound. Even when i'm not playing anything, the sound remains there. Do I need to get an audio interface to get rid of the horrible sound? (BTW, There is no hiss when I have it connected to my phone so I know it was something to do with my desktop.)
If you are indeed using these monitor speakers as studio monitors, then you should 100% get a properly shielded, balanced, professional-leveled system. You won't have to pay much if you don't need any inputs or many outputs. Studio monitors like KRKs aren't meant to be used with on-board sound, especially not the output from a laptop.
