Default Third Stranded wire in RCA Interconnect Cable

Hi,

I just replaced a damaged RCA connector on the amplifier side of an interconnect cable. When I peeled back the outer insulation I found 2 small insulated wires that I striped and connected to the new radioshack RCA connector. Everything works fine but my question is I also saw an uninsulated silver stranded wire in addition to the 2 insulated signal wires. What is this third wire and does it need to be connected to the new RCA connector? Thanks.

Generally, there is one center conductor and one shield (uninsulated) The shield is connected between the RCA connector shields.

In cables where there are two insulated conductors and a shield, the shield is sometimes only connected on the source end and the insulated conductors connect between the shields and the center conductors on each end of the RCA cable.

I guess I don't have to worry about it then since it's not on the source end. I'm just wondering, if it was connected where would it attach on the connector? (there are only 2 solder points, for the + and - which are used by the 2 insulated wires)

For a cable with 2 insulated conductors, it may not have a connection on the amp end.

Probably just a static drain, some of the monster cables came with them and it never seemed to matter which end was at the source.

I asked that question before, someone told me that the center wire could serve as the remote lead. Although I don't think I'd use it for that... I like to keep signal and voltage separate.

Did you mean, the RCA cable has two shielded wires (L & R) and then an unshielded wire in the center?
