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
Balanced/unbalanced mode of the Seventy is selected by jumpers on the main board. 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".
Way to go Gbart!!!!!
BTW, the allen key size needed is 5/64".
Thank you very much
I did what you told me...and BINGO...
Thank you every much.
Great news. Enjoy and welcome to the Classé family. :-)
