change something in signal wiring , or change something in mains cables - find a way to break safety earth for , say, monos
use either cables without safety earth wire , or T adapters without the same
be aware that you can use that trick only when everything is connecetd , so amps without safety gnd connected through mains cables are effectively having safety gnd through signal cables
pretty much normal thing in PA gear , most amps having switch on back side for several arrangements of safety gnd

When you start multi-amping, noise generated by ground loops starts to
rear its ugly head. Most often the loop is in the AC Earth connection, so
that is a good place to start. I usually isolate the AC Earth on various
pieces to see how it affects the noise and proceed on that information.

maybe on the former condition of the pages the wanted schematic is present as pdf file (checking out needs time unfortunately):this is question for Pass himself ..... I don't have any schematic for T400
as far as I can see , T400 is made 1998 , while Pa left Treshold year before ....
so - that's probably why I don't have schematic
edit: yeah , as usual , while I was typing ......

any news?Thank you, I try first with some isolating material between plug and socket earth wire of the amps. I'll keep you informed

Thanks, is it in there somewhere? I went through all of the "treasure" pages and couldn't find anything on the S450e.check in my blog (see sig)

Here is what I have, don't know if this helps or not. I don't know if the FEB is the same for preamps and amps. I have a FET 10 Pe, and I have collected schematics over the years of ownership, including the original owners manual which shows the DIP switch settings for the "e" model.
