Classe Seventy

I've just acquired this amp. I can only get it works using Balanced input. There are no sound when using unbalanced. Please help. Thank you

You will need to reposition the jumpers for both channels to switch to unbalanced mode. Remove the top cover with an allen wrench and move the two jumpers from the position marked "BALANCED" to the position marked "REGULAR".
