Khozmo 64 steps ladder attenuator grounding question

[Superchunk]

Please first use the correct terms and understand (or google) what "earth" and "ground" are exactly. Then try PE and GND.

Many misunderstandings come from the habit in english speaking areas to call 2 different things by the same name and as a consequence by using their applications mixed up.

Casing/chassis is connected directly to PE for safety. GND is at the secondary side of a PSU and used as conductor in audio circuits.

Did I make a mistake in terminology somewhere?

Nah. We all understood what you meant.

It was Richard Feynman who said when a student knit picked "Don't listen to what I say, listen to what I meant"

"Input ground - khozmo ground - preamp input (-) ?"

Those are all signal ground, yes?

"- khozmo ground lug to earth"

And the khozmo lug does connect to earth (which I called ground because...it grounds to earth, but wrong term there)
