What happens if...

...I cheap out and start using 75-ohm component video cables for interconnects?

Anything fun? Bad? Just gotta crank up the volume a little more?

 

[ooheadsoo]

Nothing. There's no such thing as 75 ohm rca, anyway.

 

[C38368]

Then why are all the RCA-terminated component video cables I've seen 75-ohm? Or S/PDIF cables for that matter?

 

[ooheadsoo]

Because that's what they're supposed to be. Not what they actually are. Impedance is determined by the physical dimensions of a plug. It's physically impossible for rca to be 75 ohm. The spec is 75 ohm so that's what they say when they try to sell you a video cable. BNC and F connectors are readily found in 75ohm size, which is why I suspect you see the relatively more "no nonsense" realm of video filled with bnc and f connectors.

 

[C38368]

Great. So there are no 75-ohm RCA plugs. I can believe that.

Now about the 6' of cable between each plug?

 

[labrat]

Deleted.

 

[ooheadsoo]

The cable may or may not be stiff. Who's to say that your regular nondescript audio cable isn't 75 ohms, anyway? They could be. There's no regulation.

 

[C38368]

Nobody says it isn't, except for adverts that claim it is. I don't really care one way or another as long as it doesn't make for perceptibly whacked-out sound and/or damage something.
This is one area of physics that just never really made much sense to me.

Thanks for the input.

You will die a horrible painful death.

Serious answer? You'll be fine. It may sound different but no more different than the difference between other cables.

I currently have a pair of them between my DVD player and my TV since I didn't feel like going through the trouble of making a pair just yet

They work just fine.
