RCAstereoliitännästä

RCAstereoliitännästä refers to the common analog audio/video connection standard, often called phono connector or cinch connector. It consists of a male plug and a female socket, typically used in pairs for stereo audio. One connector, usually colored red, carries the right audio channel, while the other, typically colored white or black, carries the left audio channel. For composite video signals, a single yellow RCA connector is used. These connectors are widely found on audio and video equipment such as televisions, stereos, DVD players, and game consoles. The system was developed by the Radio Corporation of America (RCA) in the 1940s and has remained a prevalent standard for consumer electronics due to its simplicity and cost-effectiveness. While digital connections like HDMI have become more common for high-definition and multichannel audio, RCA connectors are still widely used for their compatibility with older equipment and for basic stereo audio transmission. The quality of the signal transmitted through RCA cables can be affected by cable length and shielding, with longer or poorly shielded cables potentially introducing noise or interference.
