Saw something like this about 30 years ago. Two back-to-back 12V zener diodes in series with the ground wire, with a small disc cap across them. At RF frequencies, the ground is solid, due to the cap. At audio frequencies and DC, the ground is disconnected, unless a fault of more than about 12 volts appears, and at that point the ground is instantly re-established. Costs less than $10 to build it into an amp.
I've had ground loop problems where one piece of equipment's 0V rail is connected directly to the chassis and earth connection, but the 0V rail of another piece of equipment is floating, so it's at a different potential from the chassis. Connecting these two units with a standard guitar cable causes a conflict between them, leading to hum.
Not a fan of the wall wart real estate that this occupies. I have a Morley Humno that goes for about the same price & is a 1’ length of cable. Check one out if you’re in the market.
If you compare the ground noise from the beginning (end of intro) to the short moments in the end when (supposedly) the device is in action - there is no difference. Don't tell me no lies and keep your shit to yourself.
From their specs on their website: AI Ground Detection: Each unit will automatically disconnect the ground on that device So either they are lying, or this is an incredibly bad idea. Possibly both.
Hey there! We understand your skepticism. This unit auto-disconnects the earth and then re-establishes it when a current fault is detected. This is how it maintains user safety-and why it's a little smarter than an average ground lift!
@@iFiaudiochannel You just restate your own marketing blurb. Where is the AI in this product and why should I trust it with my safety? In engineering terms, not marketing fluff.
@@veers0r To clarify further, while the breaking of ground loops is indeed automatic, it does not involve "machine learning" or "artificial intelligence" in the way those terms are typically understood today. Machine learning implies that the device has abilities that allow it to learn and adapt based on user input, which is not the case here. Once voltage exceeds a certain threshold, the ground connection is reinstated through bypassing of components. No snake oil here, just smart engineering.

Hi James, I have two using on my monitoe speakers, really great. Will try this on my 60th Anniversary VOX AC30!:)👏🏻👏🏻👋🏼
Does this work the same way as the Morley Humno?

Ok. Good tech. But 99 bucks?? really???
Yes. This stuff ain’t cheap. The EBTECH Hum X is about $80 and it’s bigger than this thing and you have to plug it into the wall.

Still hums just not as bad.
Slightly un-sexy - but vital! A good watch
"improve the sound of the amp by cleaning up the earth issues" 🃏 what a giant bullshit
no Demo Then?
@@mrandonnio watch the full video and you should get the idea.

@@iFiaudiochannel Calling it AI is being economical with the truth then. Not sure whether that does your product any good.
Absolute bullshir
