I'm having a bit of trouble with my amp. In the owners manual it shows a red LED under the smoked "glass" with the word "overload" next to it and explains what the deal is should you see the LED light up. In my amp, I see the red LED next to the word "overload" and it is NOT lit up. However, in the smoked "glass" on the other side there is another red LED and it IS lit up. Does anyone have any clue what this LED represents? It says nothing in the owners manual. Any help would be greatly appreciated.
