How do I connect component audio cables to rca audio cables?

Are "component" and "RCA" cables the same?

  • Can one use RCA cables (red/white/yellow) in component jacks (red/blue/green)? I understand that the jacks carry much different data/signal/whatever, but I was told that there is no need to buy (very) pricey component cables...you can actually just hook up good quality red/white/yellow RCA cables to the component jacks for the same purpose.

  • Answer:

    Sorry but all the previous answers are wrong. Video cables (the yellow ones, or the red/blue/green ones) all have to be made with 75 ohm coax. This is so they exactly match the impedance of the input jacks on the TV. Audio RCA cables (red/white) can be made with 50, 75 or 110 ohm coax. These will appear to work for video cables, but there will be some damage to the video signals. STANDARD DEF vs HD The other problem is "Component" is a standard-def cable. They have been made for 40-50 years. Most of these cables are not designed for the higher frequencies of HD video. Just because you spend $25 at Radio Shack for component cables does not mean they are compatible with HD video.

Basically. The difference is that component cables are generally higher quality and better insulated. In lengths of 6ft or shorter, I wouldn't spend extra.

Your talking about RCA audio vs RCA for component video, They are pretty much the same thing but not exactly, the resistance spec are different for audio and video, also if you are trying to pass a 720 P signal you will need a better cable, especially over a longer distance; cheaper audio cables have two conductors while the better component cable recommended for HD (720p) has three conductors positive negative and ground, its similar to the difference between three prong electrical plugs and two prong electrical plugs they will both work but for heavy duty work you want a three prong plug, so for 480i signals any RCA cable will do but for HD 720P and longer distance runs you want a shielded grounded cable...

Yes, you can use the compsite (Red, White and Yellow) cable as a component (Red, Green and Blue) cable. Hope this will help you out.
