It was explained to me once by an electronics engineer, and I think that he told me that there is a built-in galvanic isolator inside the converter of the Ethernet stream from optical to analogue.
But it’s very possible that I don’t remember well what he actually said, and that I’m messing with something else.
Anyway, I have two Delocks, like the one to which I provided a link.
One of them is for the decoder of the TV. And it improves the streamed picture.
I use the other one with an audio streamer, and on this end poind, the Padlock provides a small correction to the timber of the sound.
I tried it on another end point, and on this one, the Padlock does not improve anything in my system.
But I heard feedback from other people who say that they get a serious sound improvement with it in their system.
It’s a cheap device, so everybody should try it, and check what benefit he gets from it.
But it’s important to know how to use it:
- The device looks symetric, but there’s actually a side that should be directed towards the streamer, and another towards the LAN. It’s important to know it.
- The device should be grounded.
- The Ethernet cable that connects the Padlock to the streamer should be as short as possible, and should not exceed 50 cm.
The Delock 62619 is the basic model. There are other Delock models who offer an enhanced isolation, and that are slightly more expensive, but they are still cheap in comparaison to the isolator of JCAT.
