So is there an optimum level setting?
No matter how I have my output level set, even if completely down at zero the red clipping lights come on.
It doesnt matter how i have the input level set 0 - 100 or anywhere in between The output still clips.
If I have both input and out put down at a very conservative level 20 each the headphones still seem to clip a little bit.
And the headphone volume seems to be really quite quiet even if maxed out at 100.
