One and a half Posted April 1, 2021 Share Posted April 1, 2021 Not so much sure protection, cause the switch or router upstream is usually charcoaled. The main benefit of the LAN isolator is to break the common mode loop and that it does quite well. intothedragon 1 AS Profile Equipment List Say NO to MQA Link to comment

Common mode noise is a conducted rubbish unwanted signal that is created from any semiconductor switching device that with its own capacitance or bolted to a metal surface forms a circuit to its 0V. It's that (very small) voltage that can transmit over signal wires that is troublesome for devices like DACs and clocks therein. From my own observations, common mode noise reduces sound stage height and depth, creates a point type source image, very much like a mono presentation. Common mode noise interferes with resolution of very fine instruments like cymbals, snare, and muffles frequencies like that. 'Air' around instruments is missing. Common mode noise can be isolated by transformers or a signal's 0V grounded to PE at various points to keep that noise from developing further through the transmission chain. Typically start with at a DC power Supply and bonding the 0V to PE. intothedragon 1 AS Profile Equipment List Say NO to MQA Link to comment
