A QUESTION? If the neutral and the ground are tied together at this box, how does that work for noise? The ground is the garbage collector right? Am I trying to dump the noise through the ground? What stop STUFF from going backwards? I mean AC is doing the Cha, Cha, Cha, RIGHT, back and forth but always towards the source, or the ground? OR Towards the source and THEN to ground or neutral or BOTH.. This is what is messing with me. What stops it (noise) from going BACK into the circuit. In simple terms. Where is the directional gadget? I’m thinking of running a common shielded very small flexible (antenna lead maybe), to a common star. I want to run a second lug to earth. I’m going to bridge between the TWO. What make it go in ONE direction? Does the ground know to suck out the noise? OR is the path of least resistance thing come into play? (MAN did I wake up foggy). :-) So this box is a "BETTER" collector of GROUND? (as if it were a thing) I dunno!! Regards |

The Ground Zero uses a wire attached to a ground post or the chassis of the components. I tried it and it seemed to smooth out the highs, that's all. @larryi I believe the active blocks use the negative of an RCA jack as ground, and the ground from an XLR input then they're tied to the ground block. Possibly also using the neutral. |
“Why use our Ground Box’s ? You will get an improvement in dynamic’s, a lower noise floor and more natural flow in the sound.” Is there no Advertising Standards Authority to challenge this sort of thing? (Not so much the dodgy claims. I’m much more concerned about the use of an apostrophe for a plural. This has to be stopped!) |
I think the alternative to such boxes is having a solid rod planted deep in the ground outside of your house with a ground wire running to a single grounding point for all of your gear. Why this is important, I don't know. But, I do know it does affect how a system sounds. I heard a demonstration of the Nordost grounding system. It consisted of such a box to which all components are connected via a run of wire from an unused input to the grounding box. Nordost supplied wires with all sorts of alternative connector plugs to fit that unused input (RCA, XLR, BNC, etc.). With the grounding installed, the biggest change in sound was to the imaging of the system -instruments and vocalist seemed to float more freely in space and seemed to be actually present in the room. The decay of notes also seemed to be more obvious and natural sounding instead of sounding cut off. I liked what I heard. I did not get to hear it in my own system and did not ask for an in-home demonstration because my amplifier does not have an unused input. I was told that a chassis grounding point was NOT an alternative to an unused input for this grounding scheme. |
All grounding schemes from component to earth have different levels of impedance (ground potential). We know this much. By no means am I an expert, but by wiring each component’s chassis (earth ground) to the grounding box and adjusting the settings, the theory is that an equal impedance to ground can be achieved. https://www.synergisticresearch.com/isolation/ground-isolation/grounding-block/ http://www.graniteaudio.com/zero/index.html Where’s millercarbon when you need him? |
well it can be expensive snake oil - https://www.thecableco.com/accessories/grounding-devices/olympus-tellus.htmlCome on, see it from the positive side. It is.......(Guaranteed lowest advertised price) |
So per the website https://www.entreq.com/products/ground-boxes-17667704 it supposes to lower the noise floor since the home electrical system is full of interference. |
