This post focuses on the differences between balanced and unbalanced connections.
When I first started engineering my high school band, I didn’t know what the difference between balanced and unbalanced connections was. I used guitar cables to link up all of 1/4″ gear and routinely used impedance transformers to convert between XLR to 1/4″ unbalanced. I thought the extra ring on TRS cables was just some weird novelty. Not so.
