What should I consider when buying a RCA cable?

The

RCA cable is most commonly used to transmit analog (non -nepic) sound signals between electronic components. The well -known cable is two -sided with one red and one white tail at each end, although some cables could replace black white. Many RCA cables have a third yellow tail to supply a folded video signal. The cable connector is a male push-in with a thick central pin surrounded by a thin rounded collar or crown. RCA cabling can also provide video signals components.

RCA cable tails are color -marked to match the correct input or output connector on the electronic device. Red tails or black tails are connected to the right inputs/channel outputs, while white tails are used for left channels. In fact, both wires are exactly the same, so switching of color does not change, but it is important that the same color is used for the same channel at each end of the cable. Because "red" and "correct" start "r", it's easyOb, how to remember how to connect cables in a consistent way, even on components without color coding.

The types of cables used to connect the components and the ability to supply signals without the introduction of interference were placed. In some cases, companies charge a huge amount of money for cables to provide excellent performance. Some of these cables have a large, complicated designed head and flashy packaging that necessarily figure in cost, but not necessarily performance.

One generally accepted myth is that gold tips or connectors are always better than silver. While gold is no better, it is non -corrosive and more affected than silver, which could be an argument for buying a plug of golden tips for applications where the plugs will be left in place. If cables are used in a patch where they will be connected and disconnected, silverrotips may actually be LEIt is a choice than the soft golden plating that can wear out.

Typical run up to 10 feet (~ 3m) does not require expensive RCA audio cable, although the cheapest possible cable - type included in many electronic components like freebia - may not be the best choice. Nevertheless, the average person would probably not notice the difference between this RCA cable and others. The speaker meter and the type of speaker has a greater ability to make a clear difference in the sound, everything else is the same than the RCA cable. Choosing a modest price cable should make a trick.

RCA cable is also used to transmit video components. The three tails are in color marked as green, blue and red to match the female connectors to video equipment. Video components break the video signal into three spectrum to give a more true color than a composite video that travels through one conductor.

Some say that because all RCA cable is rated to 75 Ohms, it may be used for any RCA application. Although it is true that any cableRCA will make a pinch, even red, white and yellow tail cable, it is not ideal and probably will not bring a clean signal. The problem is that most RCA cable is not a real 75-ohm, specifications required by video.

RCA cable began as an audio cable, required 50 ohms. The sound works at relatively low frequencies up to about 20,000 Hertz, but the video covers a much higher frequency range, up to 35 megahertz for HDTV. As a result, it is more susceptible to factors such as non -conformity impedance that can create signal interference and degradation. In this application shield and cable design, it is more important to avoid influences such as spirit and general quality loss.

For these reasons, it is best to buy a RCA cable specially designed to connect components that are close to the real 75 Ohms. Unfortunately, marketing sometimes trumps the facts and the price does not always guarantee quality. The most expensive cables are likely to be too much sold with hype while the cheapest cable componentsEnty could be no better than the average RCA cable at an inflated price. Look for brand advice on AV forums and related websites. If you shop from a local dealer, avoid chains that carry the only overpriced product line.
