It does not absorb, as to absorb a capacitor or battery will be needed which needs to be discharged.

Instead, a transformer(Or i should say many, number increases with increase in price, and frequency gets divided between them) is used. as audio signals are analog, the transformer induces only audio waves to the other side and not the extra current which comes with it. This way it is able to remove any sort of excess current. this way, not only does extra current is removed, it heavily increases sound quality by also filtering the noise. and make it crystal clear.

A similar version was also used in the old days with a Cable TV, so as to remove noise from the video signal.

And now you can use it with your pc without worries.

received the ground isolator today-after connecting it to the 3.5 mm aux cable of the speaker,my tester doesn't pickup any more current from the 3.5 mm output connector of the isolator-does it mean it has successfully removed the current that was leaking from the speaker via its 3.5 mm aux output?

if yes,is it safe to connect and use it with sensitive devices like computers now?

btw how exactly does the isolator remove the current from the cable?does it absorb it somehow?

how long do these devices last?Can the transformers inside these things fail after a certain period of time?

usually they should last a good amount of time (3-4 years minimum) as not much of mechanical load or work is done by it.

Yupp, Interference from mobile radio circuitry often conflicts with audio amps, causing a noise drain through ground. this thing just isolates that.


Here found a video on it. Its pretty much the same concept, but on a smaller scale
