Term: Coaxial Cable

Standard 2-conductor shielded cable comprised of an outer woven metal shield (the ground connection) covered with plastic/nylon insulation and further insulated from the inner “hot” or positive wire. Used with RCA male plugs on each end for routing low-level  analog audio signals from CD players, DVD players, cassette decks, set-top TV converter boxes, and satellite receivers to A/V receivers and amplifiers.

The RCA plugs are often color-coded red for Right channel and white (or black) for Left. Also used for composite-video connection (color-coded yellow) and may be used for digital coaxial audio connection as well. Coaxial audio cable is also used between the A/V receiver’s subwoofer output jack (color-coded purple) and the subwoofer line-in connection.
