| RCA connectors
In the days before CD players, the
Radio Corporation of America (RCA) developed RCA connectors to connect
turntables to stereo systems. But with the advancement of audio-video
technology, RCA connectors are now used mainly for carrying video and
line-level audio on stereos, TVs, and VCRs. If you've ever connected your
VCR to your TV, then you've probably seen one of these cables. They have a
center contact (a pin or a hole) and an outer contact (a flower or a
cylinder). Some very early versions of the Mac use RCA connectors to hook
up to a TV. |
