Hi,
Ok so its been a while, as most of you know i am using the XMD1000 and am gettting ground noise in the line in.

I tried grounding the XMD chassie as most of you suggested and still no difference. I am now using a computer with a DC to DC power supply. when I mute the line in it is perfect, it is also perfect with the line in unmutted, however as soon as I connect the XMD and it is operational it has a buz and hmmm..... i also get the alternator whine, what would u guys recommend!!!
