Are your cables balanced? If not that can cause buzzing.

excuse my ignorance but what does that mean?

Sounds like a ground loop issue to me.

You need to check if the cables you're using a balanced - the type of shielding that surrounds them, it might say on them, it might not! Try some grounded cables though to rule that out - sounds like the issue to me.
