AV cables same as component cables, aside from color? - Contractor Talk - Professional Construction and Remodeling Forum

mickeyco · 12-08-2008, 03:36 PM

Hooking up my new TV, I want to hook up my DVD unit and the input is a "component" input (red, green, blue in color (red and white for audio)), is the difference between the component cables and the A/V cables only the color/ meaning can I use a yellow in place of a blue, or red, or green as long as they go from blue to blue. red to red and green to green?

Do what I do.
Get a 14 year old to do it for you.

Yes you can. Where is the HDMI output at?

The electrons are very particular on who they associate with.
Red doesn't want to be white, white doesn't want to be green, green wants to be red.

With RCA jacks, the color coding is a standard:
Red = Right audio
White = left Audio
Yellow = video

You can do whatever you like as long as you don't cross colors between components.

Don't know, I'm just replacing a crap TV that had two VCR's, a DVD player and a DVDR hooked up to it and I don't want to run out and get cables (I'm lazy, plus I hate shopping).

They're the same, I put a meter across them and the impedance is the same (borrowed my neighbors green cable), now I just have to decide if I want to buck the system and mix colors, to hell with societies rules I'm going to mix the colors, I'm a rebel.

Same cable. It's all analog, the colors are only for reference.

BuildingHomes · 12-08-2008, 10:07 PM

Yes you can.

Just make sure that what you plug it into on one side matches on the other.

If faced with the situation of just having a video/left/right (yellow/white/red) I do yellow to green, white to blue, and red to red.

They are all 75 Ohm cable (or should be). Just don't use the thin ones over a long distance and you will be fine.

Video (component) video cables are standard 75ohm RG59 or RG6 coaxial cable.

Audio cables are a twisted pair design or 75ohm cable, either will work fine under most situations for audio signals.

You do not want to use twisted pair cables for a component video...in that respect they are not the same as a component cable.

Do you have a picture of what a twisted pair audio cable looks like?

Greg C · 01-22-2009, 08:43 PM

If they are a short run, under 2 m it will work. I would not use them if it was longer due to issues of signal getting too weak. The audio set on an AV set are a smaller AWG then the video.

Same concept as a CAT5 cable, but with one pair...
Usually they are foil shielded. Some of the better cables also have braided sheild and a drain wire.

But that doesn't really make much sense.. The twist is usually used as differential in a balanced signal, such as 100-base-T ethernet for a cat5 cable.

Standard line-level audio is not balanced, it's a signal and ground with a physical carrier either being a pair of equal length conductors, or a coaxial cable. Coaxial probably working better over longer distances.

But if you are using it over a really long distance then you would use a couple of baluns to convert the unbalanced signal to a balanced signal and run over cat5 twisted pair.

Are these balanced audio cables some sort of product from Monster?

sirroundsound · 01-29-2009, 11:51 PM

Monster I250 is twisted pair with shield.

ctiautomation · 03-27-2009, 01:44 PM

yes. you can.

Cheap analogue audio cables are coax typically MINI RG59, better analogue audio cables are twisted pair sheilded with a drain connected at either the destination or source end. Digital audio and analogue video are almost always coax such as RG59/MINI RG59/RG6 or something similar, the video is a way higher freequency then analogue audio and it very subject to voltage differentials.

....All that being said they all friggin work....I've put paperclips accross the signal to bridge amps and it works just fine; don't waste money on fancy cables its all bogus. I use to make custom A/V cables, it was boring as hell but I can talk about cables for a lifetime.
