RCA cables have been in existence since the RCA connector was created in the 1930s. Despite being nearly 100 years old it remains a viable and effective way of connecting two musical devices. Initially, the connector was created to join the phonograph to a radio receiver.
Today they are used to connect preamps, mixers, amplifiers, entertainment systems, and even some game consoles. The standard RCA cable has three connectors built into one cable. They are generally color-coded, yellow, red, and white. This ensures the connections are the same in both devices. The white and red cables are designed to carry audio, giving you two channels. This effectively allows for the transference of stereo sound. The yellow cable carries the video, ensuring you can see as well as hear the data you are transmitting.
It should be noted that RCA cables are designed to carry analog signals. You won’t get the same image quality as with an HDMI or other digital signal. That doesn’t stop them from being an essential cable for many people.
However, if you are lucky enough to get an RCA cable with your device you are likely to find it is not long enough. While there are longer cables available, to give you the best possible freedom of movement, you should purchase an RCA extension cable.
RCA Cable Design
Each connector houses two wires, a live and a ground, allowing the circuit to be completed and the signal carried effectively. The male connector has a metal piece that sticks out in the middle, this is the live or ‘hot’ wire. The circular support behind this is the ground.
It should be noted that because the live wire connects first, before the ground, you will hear a buzz that sounds like feedback. The only way to avoid this is to make sure the equipment is turned off when you plug your RCA cable in.
Considerations When Purchasing RCA Extension Cable
Having decided that an extension cable is a good idea to allow you to position your devices correctly, you need to make sure you get the right cable. That means spending a few moments thinking about the following:
When you are looking for an RCA extension cable you need to consider who has made the cable. If you know and respect the manufacturer then you should feel confident purchasing an RCA extension cable from them.
However, if you don’t know them or haven’t had a good experience with them, proceed with caution. It is a good idea to ask family and friends what they think of the manufacturer and supplier.
If they can’t help you need to look at social media. You will find a selection of people prepared to give honest opinions regarding a manufacturer/supplier and their specific products. This information can be invaluable to you when deciding which RCA extension cable.
The purpose of an RCA extension cable is to extend your existing cables and allow you to position your devices almost anywhere. However, you will lose signal quality if your cable is too long. That’s why you need to spend a few moments realistically considering how long you need the cable to be. You can then find one that is the right length, ensuring the signal is still good and the cable is long enough.
It is always worth taking a few moments to look at several different products. This will allow you to establish an average cost. If you are looking at something significantly more expensive than average you will need to know what you are getting extra.
Equally, if the extension cable is a lot less than the average you should be concerned regarding the quality of the cable.
You should note that some extension cables have shielding built into them. This protects the signal inside the cable from outside interference. If you want the best possible audio and visual experience it is a good idea to purchase an RCA extension cable with a good level of shielding.
Lastly, we’ve talked about how RCA cables usually come with three connectors for stereo sound and video. However, the cables can have just two or even one connector. You’ll need to consider how many connectors you need for your extension needs.
