Hello,

I own a few Matrix-1000s, one of which is making some hiss at higher mixer volumes. In addition, its power supply is warming up considerably more in comparison.

I wonder if changing the power supply is possible, and could the hiss be due to a ~faulty power supply?

What is the optimum volume knob position in terms of maximizing the life-time and minimizing the hiss in case of a Matrix-1000? I normally keep the volume at 50%. But, what is recommended?

I guess the Matrix-1000 can "burn-out" in substantially shorter time, if the volume is kept in its maximum position all the time.
