If the ground connection is broken by the plug partially disconnecting from the jack, breaking the ground connection but not the signal, continuous noise can occur. If the audio components are powered when they connect but do not have a common ground, the result is a loud hum or buzz. Grounding issue: The signal-carrying pin, which protrudes from the plug, frequently makes contact with the socket before the grounded rings meet. Standard: Cables should meet the S/PDIF specification as defined by the international standard IEC 60958-3 for assured performance.ĭimensions: The center pin of the male plug is 3.175 mm (1/8”) in diameter and is surrounded by an outer shell which is 8.25 mm (1/3”) in diameter. Component analog video/VGA (RGB/HV) – red, green, blue, yellow, white.Component analog video (YP BP R) – green, blue, red.TVs have multiple sets to allow additional connections to portable video sources such as camcorders and to video game consoles. Stereo audio – red for right audio channel white or black for left audio channel (typically found on the back of audio and video equipment).Analog audio – white, red, black, yellow, green, blue, gray, brown, tan, and purple depending on specific function. Variation is acceptable as long as the cable is compatible with the application (e.g., cables with 75 ohms impedance for video and S/PDIF) and in many cases the color schemes have been simplified. Standard colors (listed below) are found on most commercially made products.
