USB Optical Isolation

[Feet]

I picked this up a while back for a project, and it didn't end up being required. Now looking to sell it on.

However, it occurs to me to ask if there's any benefit to it in my audio chain. Just got a Caiman SEG, so not really used USB digital audio much until now. Not sure what kind of isolating the DAC includes.

Also not sure about data rates, etc. Currently using a USB 3.0 port from my surface pro into the DAC. This isolator is USB 2.0.


Would it be useful between PC and DAC? Or isolation in DAC is fine and it's just introducing an unnecessary extra component in the chain?

The diagram on the casing of the unit suggests that it uses isolation transformers. This from Google :-

Pulse transformers are a diverse family of transformers designed to transfer a digital control signal from a control circuit to a load. They provide galvanic isolation to a circuit, whilst allowing fast control signals to be transmitted without distorting the signal shape.

The reference to "Pulse" refers to the Pulse company that manufactures these things.
