A video and audio port are a jack or port that receives a video and audio signal from another device or video output source. The composite cable is a popular type of video input cable. Five common cable connectors are used in live sound: TRS and XRL (for balanced connections), TS, RCA, and banana plugs (for unbalanced connections). The tips, rings, and sleeves of the shaft are the Tip, Ring, and Sleeve. TRS connectors are used when two conductors and a ground (shield) must be combined in a single plug, as shown in this Video and Audio Ports diagram. XLR cables, the most common 3-pin balanced cable, are the industry standard for connecting microphones, preamps, mixers, or line-level signals to speakers.
