I'm inclined to disagree. I've seen songs that have a constant low rumble and the line stays off the bottom. Also, for resons I can't yet determine, when I listen to my aux (alpine) input and turn it off, It must close the inputs in some manner because the line goes to the top. I'll have to do more testing with this and see what is actually going on.
I believe the display is correct.
