RCA Audio Video Cable

RCA cable can be used to connect a variety of audio and video devices, such as camcorders to TVs or stereos to speakers. Higher-end camcorders will have all three RCA jacks, and so the signal entering or leaving the camcorder can go through three separate channels (one video, two audio), resulting in a higher-quality transfer. Lower-end camcorders, however, usually only have one jack, called a stereo jack, which combines all three channels. This results in lower-quality transfers because the signal is compressed into one channel. In either case, RCA cables transmit analog, or non-digital, signals. Because of this, they cannot be plugged directly into a computer or other digital device.
