what is true ground??

[sts9fan]

"Also, make sure that the -
outputs on your main amp are true ground, otherwise you would short the output of your main amplifier.
Call or email technical support if the - outputs on your main amplifier do not have true ground."


what does this mean??

true ground

in its strict definition is just that; ground..Ie a metal stake pounded into the ground and all grounding wires tied to that single point or post. There is zereo voltage. The problem and especially in a cluster f??cked house wiring is that the ground wires may be attached to other ground wires first before reaching that metal post. This creates what is called a ground loop. When this occurs, what you may think as ground may be actually floating a small voltage between the ground loops. This causes no end in headaches.

Now how this applies to your amplifier, I'm unclear because I do not know what "? - ?" means .

But, that was a pretty darn good answer.

I don't know where the ?-? came from I cut that from the instructions in the manual of the Hsu amp on how to connect the amp from high level outputs.
