ok, but i don´t get any hum when the whole gear in 4cm is hooked up...but only when i add the usb to pc connection...can it still be that the ebtech tool is the solution...? where should i place it then...?
thanks
yes...Out of curiosity, are the AX8 and the computer on the same A/C power circuit?
And somebody asked how hum-eliminators work... simple: they are transformers... the input and the output are electrically isolated by a gap. The signal is passed by entering on the primary, and being magnetically induced into the secondary - the output side. Voila - physical separation!
