Looking through the forum and manual I could not see clarification on verifying input levels are free from clipping. I have a tube amp running into a Weber Max 200 Load box with line out into the HX Effects. The inputs and outputs are set at line level, but since I cannot see a meter I am not sure how to check that the line level input is not near a clipping level. It doesn't sound like it is, but the load box has an adjustable level knob so I was curious how far I could push it before it starts
