We have a DC Male To RCA Socket Cable, but many people do not know what is RAC, when To use a DC Male To RCA Socket Cable, let me introduce you.
RAC stands for Radio Corporation of America (RCA). The RCA connector was invented by the Radio Corporation of America. RCA commonly known as lotus socket, also known as AV terminal, also known as AV interface, almost all TV, DVD player products have this interface. It is not designed specifically for any one interface, but can be used for both audio and regular video signals, and is also a DVD component (YCrCb) socket, though there are three of them. RCA is usually a pair of white audio interface and yellow video interface. It is usually connected using RCA (commonly known as lotus head). You only need To connect a standard AV Cable with a lotus head to a corresponding interface such as DC Male To RCA Socket Cable.
Transmission of signal
RCA terminal adopts the mode of coaxial signal transmission, the central axis is used for signal transmission, the outer ring of the contact layer is used for grounding, can be used in analog video, analog audio, digital audio and color difference component transmission. RCA audio terminals are typically color-coded in pairs: red for the right channel and black or white for the left channel. In some cases, the mid-channel and surround channel connections are color-coded to make them easier to distinguish, but all RCA connections in the system are electrically identical. Generally speaking, RCA stereo audio lines are left and right channels for a group, each channel appearance is a line.
advantages
The AV interface enables the separation of audio and video transmission, which avoids the degradation of image quality due to audio/video mixed interference. The most widely used interface for audio and video devices is provided on almost every audio and video device for audio and video input and output.
disadvantages
Since AV interface still transmits a mixed video signal of brightness/chroma (Y/C), it still needs the display device to perform brightness/color separation and chroma decoding before imaging. This process of mixing and then separation will inevitably lead to the loss of color signal, and chroma signal and brightness signal will also have a great chance to interfere with each other, thus affecting the final output image quality. AV still has some life left in it, but the insuperable drawback of its Y/C hybrid makes it impossible to use in situations where visual limits are being pursued.
