I said *almost* certainly, because the vast majority of these cases are simply a gain matching issue. Let's see if this makes sense based on what was said -please do explain this gain matching as I've done it via an oscilloscope and the way that audiocontrol recommends. I've also set all adjustments to the lowest possible settings. so if my setting are as low as they go and the hiss is still there please do explain how this is a gain matching issue?
You said that when you connected your speakers direct to the h/u, you got no hiss. Subsequently, when you removed your 6xs, the hiss was almost entirely gone. Because of this, we can conclude that since the speakers, amplifier, and head unit work well without the 6xs, then speakers are not the problem, the head unit is not the problem, and the amplifier is not the problem. That leads me to believe the noise is directly being caused by that unit. Agreed?
If this is the case, there are two options - either it's broken, or else it's user error. Now are we on the same page? You have the unit plugged in and it is producing a hissing noise, turn the gains all the way down on the unit; you then said you tried turning the gains down all the way, and it's STILL hissing at you, which leaves only one possible solution - perhaps yours is just a bad unit?
I see you're frustrated, and I would be as well. Try to take it easy though.
