I am about to install a set of Leviton RCA 110 connectors and I am confused about the wiring. The connectors are designed to use 2 pairs for each channel so it takes a full cat-5 cable to carry both right and left audio. When I put a meter to the connector it looks like the 2 pairs are just wired in parallel so I have to wonder if they are both really needed? What would be the impact of just using 1 pair per channel? I am just running audio on this line so no high frequency stuff. Am I missing something or would 1 pair per channel work OK?
