Is there a way to lower the amp gain (surely inside the monitor itself), not the input gain, to reduce the little "ish" signal noise that come out the R65s. The problem is not my input here. But since the monitors are less than three feet away I keep earing this soft signal (kind of pink noise). I do not need the whole power of the amp so I figured out that I could lower the output gain a little... If possible, of course.
