Recently came across this grounding noise reducer from Telos audio taiwan.

There are many passive ways to eleminate the ground noise. So what Im thinking is why not active way? any ideas just like shunt regulator?
At a quick guess I would imagine the working principle is the assumption that most people don't understand voltage?
The reference point for a circuit is whatever you choose to call the reference point. Having chosen it, you then have to design the rest of the system accordingly. I suppose if someone makes a mess of this then someone else can make some profit from selling them various amounts of compensation circuitry.

there might be many ways but to correct the ground zero what happens if there is an offset of few millvolts of constant voltage?
I dont understand the block diagram. Kinda vague. Environmental potential generation circuit.??? Huh?
I don't think we are supposed to understand the block diagram; we are supposed to bow low in awe and wonder, then reach for our wallet.
Interesting. How can we manipulate ground zero when this device is still reference to the "ground" which it's going to correct it?
Read the other, uh, material on the seller's website. They are not constrained by conventional engineering principles, nor are they fettered by the mathematics of linear systems.
Consider any ground loops or even noise in ground is very common and its not to absolute zero it has some value as much as 100s of micro volts or so.
If you take a power conditioner it does conditioning only for Line and Neutral not to earth. Earth is the one which is as much contaminated as the L and N.
Now consider a DC servo method where the signal ground which is connected to the mains earth which is contaminated by either a digital CD player or a hair drier or lift in the house. One way or other its dirty. So what Im saying is look at salas shunt which reduces the noise to as much to nano volts. So there is no treatment done to the ground which is left without any correction. Now thats what Im saying can there by any DC servo which corrects the signal ground to zero? I agree the quality of opamps or Jfets play a significant role.
Before going into details, how does it know the ground is not absolute zero? It must need a reference which I think is the ground on wall plug. Wait... Did they just say the ground from wall plug is not clean?
Man, that website is just...depressing.
Where are we going to wind up with all this nonsense? Will our critical thinking skills ever evolve beyond the need for it?
Thank you for confirming that you are someone who does not understand voltage, and that therefore you are a potential customer for this device. There is no such thing as a voltage.rhythmsandy said:
I didn't bother to look at their website; I didn't need to as the block diagram given in post 1 was sufficient clue that this is pure snake oil. As usual in these cases the only question which matters (in a moral sense) is whether they believe in this stuff or are merely hoping that their customers do.
Offset relative to **WHAT**?
IF it´s Ground Zero and by definition *THE* Reference point, by definition it´s ZERO volts away from itself.
I'll save you the trouble 😀
This is not a demagnetizer for CDs, mind you that would be crude, it is a quantum harmonizer.
stop man stop i cant control laughing. What the hell are these guys doing in Thailand Quantum Mechanics in Thailand? Interesting. When did the Government started to invest in Quantum stuff, they have to be at NASA. Let me get by adress book i know few guys at NASA.
