Hello, I have just purchased a new Orban 8100a processor whose reputation is well established, as it has listening quality, but having just received it I have connected my source to the "upper band TB2" inputs. ", but impossible to have sound output on" the lower band TB1 ". Would you have a bad connection, bridging or other? Does anyone have an 8100a orban and could help me? Thank you while waiting for your help, see you soon.
Olivier.
