Where do I plug the yellow cable? Let’s find out. The composite cables, or the three RCA cables, are the yellow, white, and red cables that transmit analog video and audio signals. These cables are color coded to quickly identify a video signal as yellow, right audio as red and left audio as white. The yellow cable is known as the composite video cable or the yellow plug.
This yellow cable is used to transfer signals to connecting device. These cables were created in the 1940s and eventually became outdated after HDMI cables became a popular standard in connecting electronic devices. These cables are used less than in the early days, yet they can be found in some places. Each cable has its purpose. A question that pops up is where to plug in each cable.
What is the Yellow Cable For?
These cables are known as RCA cables as it was first produced by the Radio Cooperation of America Red, white and yellow are not the only set of colors these cables come in. they can also be found in other colors.
The yellow cable is used to connect video signals. This is used to connect or carry analog video. The red and white are for the right and left audio signals. We refer to the yellow cable as the composite video cable or connector. In some TV, the video connector will not be in yellow and will have a video mentioned in it.
Suppose you fail to connect the yellow cable. In that case, the video will be in black and white. The maximum resolution this yellow composite cable can produce is 480i NTSC, So the quality is limited to watching old low-resolution videos on VCR and old retro type of games.
Is Yellow Cable Positive?
The yellow composite or RCA cable is neither positive nor negative. It’s a transmission cable used to transmit analog signals. These analog signals are transmitted between gaming devices, DVD players, TV, and satellite boxes. These cables combine synchronization signals and video signals to create images on the TV screen. Since these cables are designed for simple transmission of electronic signals, since this is a transmission cable for analog signals, this has no negative or positive charges.
It has no positive charge because it’s a passive cable, and we know passive cables cannot carry electric signals. The cable is made of conductive material like copper, only to transfer and not produce an electric charge of its own.
Where Do I Plug the Yellow Cable?
The yellow composite cable is usually plugged into the video connector port of the device receiving the video input. In many devices, the video input port is indicated as VIDEO IN or AV in. this is found on the side of the TV or at the back.
If you want to connect the yellow composite or RCA cable to the input device, locate the composite video connector on the device that corresponds to the color code yellow Make sure the cable is connected securely from the ends, the device, and the TV. Now after connecting, select the correct input into the TV using the input button on your TV remote. This can be done using the TV menu setting.
How to Connect Other Composite Cables?
The composite cable set has three main cables to transmit video and audio analog signals from one device to another. This can be from a DVD player to a TV or gamer. These cables have color-coded connectors from both ends of the cables.
The colors are red, yellow, and white. The cable connects the right audio to analog signals, and the white cable connects the left audio to analog signals. The yellow cable connects video signals in analog as red, green, and blue, giving color to the black-and-white image produced. These colors are combined to produce a quality image on the screen.
The composite cables provide better image quality than other cables like HDMI and component cables Because component cables can separate color components and reduce noise and interference, unlike composite cables. These cables cannot promise high-definition video signals produced by HDMI or display port cables.
To connect composite cables;
- First, identify the composite cables to their color codes. Identify the input and output ports of the devices.
- Please make sure the devices connecting the cables are turned off. Identify where the cable connectors are located on the device. Some devices have it at the back, and some have it at the side of the device.
- Now check for the label on the cables. Some are of the colors, and some have color and name labeled. For example, the red cable to the red port will have audio right mentioned.
- Once you have identified them, connect the red cable or connector to the red port or correct audio input of the device. Next, connect the white cable or connector for the left audio port of the device.
- Make sure all the connectors are secured and tight. Loose connections can fail to transfer the signals, disrupting the connection efficiency.
- Finally, turn on the device and check for signal transmission. Make sure the composite signals work.
Conclusion
The composite cables have been used for many years, as audio and video connections. These cables are simple and easy to use. These cables need to be updated and have many limitations compared to the HDMI cables we use today. These limitations can be seen in terms of resolution and video quality.
A significant disadvantage of composite cables is the lower video quality and resolution compared to the current type of cables. The maximum resolution these cables hold is 480i. So, we cannot use these cables in today’s technological devices as we have very high-quality resolution cables these days.
Even though composite cables are not as popular as in the 1900s, People still use them to connect old game consoles, DVD players, and VCRs to old TV and monitor. Overall, composite cables are simple and basic to connect audio and video transmission.
