I have a 3 conductor wire that are all wrapped in a foil shield with wire conductor, for a total of 4 wires.
I am connecting the 3 inside wires to audio left, right, and ground. This is an unbalanced setup, right?
In this case, should I be shielding the left from the right as well? what about audio ground?
Where/how do I connect the shielding?
Do I connect both sides (i think no?)? Which side? To where?
My choices for where to connect the shield: audio ground, chassis, nothing
I would like to avoid all ground loops and noise.
If I felt like putting on some EMI protection and have some braided EMI shielding roll, should I bind the EMI shielding to the foil shield to make one shielding conductive layer or should I separate the shield layers with insulation? any pros and cons to each method?
Do I connect both sides (i think no)? Which side? To where?
My choices for where to connect the shield: audio ground, chassis, shield (wherever that may be connected to), nothing
I feel like I've seen some manufacturers with multi-layer shielded wires that have separated layers, others that are together, and some that have a combination. What are the benefits?
Please make the distinction between EMI & RFI, since most of the colloquial speech involves using EMI as a catchall for both EMI & RFI, but as I understand it, they are two different things with two different requirements and it can be confusing to me.
If you believe foil is "better" than braided, please provide facts as to why and how, as it is my belief/understanding that they are each designed for different purposes and would like to understand your reasoning.
I have no electrical engineering degree, so I could be wrong.
