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? 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?
