The RCA connector [3] is a type of electrical connector commonly used to carry audio and video signals. The name RCA derives from the company Radio Corporation of America, which introduced the design in the 1930s. [4] The connector’s male plug and female jack are called RCA plug and RCA jack. It is also called RCA phono connector [5] or phono ...
For example, an 8 m (25 ft) star-quad cable has a capacitance of 150 pF/m [10] for a total capacitance of 1200 pF for the entire length of cable. With a 150 Ohm source impedance and 1200 pF load capacitance, the frequency response of this RC circuit is -0.02 dB at 20 kHz.
Audio only: Analog: Often unmarked on consumer audio equipment since it is so common, or labelled with headphones symbol or as "line out". Computers and other equipment sometimes use Microsoft-Intel color coding scheme, especially when there are multiple input/output plugs. 3.5 mm TRS minijack RCA connector: Balanced audio
Three RCA connectors - yellow for composite video, and white and red for stereo audio RCA connector: Widely used in consumer electronics for audio and video. A single connector must be used for each signal. SCART: Consumer electronics, mostly in Europe. Carries analog stereo sound, along with composite video and/or RGB video.
Ordinary lamp cord has an inductance of 0.1–0.2 μH/ft, likewise for shielded cord, [6] so a run of up to about 10 feet (20 total feet of conductor) will have less than 1% inductive loss in the audible range (10 ft * 0.2 μH/ft = 2.0 μH, which is at or below the proximate threshold of 2 μH given above). Some premium speaker cables have ...
Cables designed for this use are often terminated with RCA connectors on the other end. A combined video/audio jack is also present on some computers; several generations of the Raspberry Pi have analog audio and video from the same jack, and Sony also used this style of connection as the TV-out on some models of Vaio laptop.
