Hi! My dealer has explained me how to plug the mains cable respecting the phase and neutral cables of the mains socket, but now I do not want to annoy him again, and I have forgotten if he told me the rule in the cable or in the rear panel of the unit. I wonder if anyone knows... Maybe TonsofFun? He (dealer) told me that I should get some improvement in the sound if I respect this rule. I do not know if I am using the right terminology in english, but the basic point is that one of the cables in the mains socket has the signal (phase), and the other does not (neutral). If these are not the appropriate terms, please correct me (I need to learn!). His explanation was the following (I hope I "draw" it right...), and I think it was for the socket of the mains in the rear panel of the unit: _________________ |..........Ground...... ..| |....Neutral....Phase...| |_________________| Is this right, or just the opposite? I do not remember if this drawing was referring to the rear panel, or to the cable... Of course, it makes a difference... I think this is for the rear panel, but I would like you to confirm it. And, of course, corrections of the jergon are welcome. I hope you can help, thank you very much.
