On one channel of my Mackie mixer, the OL light is on whatever I do. The channel sounds like it's working but the OL light is lit. What is the reason?

Try turning the gain all the way down and unplugging the channel. If the overload light is still lit, then there is a fault with your board.

Ok. I will take it with the store where I bought it. The channel sounds OK, it might be a glitch with the light itself. – Programmer 400 Jul 17 '13 at 22:19
