What I would do is get one of these:

Run from the USB port on the PC (Not the headphone out) into the USB Box, then to each speaker. Can run mono or stereo. Will give you a solid, noise-free signal. (I know, I have one)


I would also reconsider the Behringer speakers. Much better options available.

Bob
