I’m wondering whether a digital coaxial cable is physically the same thing as a composite or component cable? There are different schools of thought with regard to this matter, which is why I’m posting here to see if anybody can provide any clarification, or better still, links to a reputable site that explains all this. Searches on Google yielded less than satisfactory results.
Opinions differ, but so far I gather that “yellow” (composite), “red”, “green”, and “blue” (component) video cables are all 75 Î© coaxial cables capable of delivering the same signal as an “orange” (digital audio) cable. Some people claimed, however, that analog audio “red” and “white” cables may vary in impedance and may not be suitable for the digital signal. Is this true? Or is any RCA cable the same cable?
If anyone can correct or confirm this information, it would be much appreciated. I suppose the simplest answer would be to “try it out and see”. The thing is, I would like to sort all this out before purchasing my receiver/speakers.
