It's going into the line input – and not Mic input – of two 80W full range active speakers with an max Sound Level of 116dB and an input impendance of 20kOhm.

The noise is already there when I set the speakers on minimal volume.

Maybe I should've bought a pair of passive speakers?

I don't know. It's kind of frustrating how less money I have left *laughs* and how much knowlegde I'm missing.

Like I said, the noise is also there..and much louder again.. on everything below that postD/A -32dB mark.
