Buying Guide

Before purchasing the RCA cable, you need to understand some essential things to look out for. The must-things to be included in your check-list are listed below: 

#1. Length

One of the most important deciding factors while purchasing an RCA audio cable is its length. Music addicts usually look for those RCA cables that are longer in length to position the speakers. The length of the RCA cable may vary from 3 feet to 12 feet. A too-long cable may be difficult to transport and damage the signal. On the other hand, a too-short cable may make it difficult to rearrange the woofers and speakers. Unless you want a cable for a concert, you should purchase a medium-sized cable. 

#2. Shielding

Most RCA cables have a shielding design that protects the audio signal from interference by electromagnetism and radiofrequency. The stronger insulated high-end cables provide a better signal and more clear sound with its noise-cancellation feature. Shielding is usually made from braid or foil or a hybrid of braid and foil. A lengthy wire may be susceptible to poor audio quality and interference from noise. Shielding is important in overcoming this issue by ensuring no interference occurs and pure audio is emitted.

#3. Connector

The connectors at the end of an RCA are crucial. The connectors are nearly identical in size and form. However, the material affects the cable’s quality and lifespan. The conductivity of various materials varies, and this can drastically alter the signal. These cables’ connections are made of gold, silver, copper, and nickel. When buying RCA, look for gold-plated wires, as this indicates their endurance. In the absence of plating, the connector is susceptible to oxidation, causing signal issues. Silver, despite its excellent conductivity, can tarnish. So go for a gold-plated connection.

#4. Quality

Apart from technical features, it is important to check the quality of the RCA cable you want to purchase. Though the quality differs from product to product, it depends on the price you are willing to pay for the cable. High-quality RCA cables offer clear, dynamic, and panoramic sounds, while low-quality RCA cables provide a dull and flat tone that may not attract music lovers. For domestic settings under certain situations, you may opt for low-quality cables, but if the sound is everything for you, you need to pay a little more.

#5. Brand and Pricing

There is n number of electronics brands in the market, and it may be difficult to differentiate between them unless you are tech-savvy. The price of the best RCA cables for audio would range between $10 and $100. Though many believe high price cables ensure high quality, the expensive cables provide only a slightly better construction. All the RCA cables are super affordable and give great value for money. So, it depends on your budget to buy a cable that is durable and trustworthy. 


Some of the most frequently asked questions include:

#1. Which is the best cable for audio? 

The connector is critical for RCA cables in terms of signal quality and cable durability. The connectors are usually constructed of silver, copper, nickel, or gold. Silver has the finest signal retention since it conducts the most. It is prone to oxidation and is thus frequently plated with anti-oxidant compounds. The gold on top is resistant to corrosion due to zero oxidation.

When choosing RCA cables, search for a connector plated with gold. Its conductivity would be better if constructed of silver or copper. If it is totally gold, its conductivity is lower than the other two materials. Nickel plating protects against corrosion but not as well as gold. Cheaper than gold plating, this is generally found on lower-end wires. If you want something durable, go for gold-plated connectors. Corrosion not only shortens cable life but also degrades signal quality.

#2. Do RCA cables differ from component cables?

Component cables are one of the several types of RCA cables. So, component wire is like other RCA cables. But there are variances in how the signal is transmitted and the results. Component cables have three video lines and two audio lines, while RCA only has one video line. Some components only have three video lines and no audio lines. In this case, they are paired with audio RCA to transmit both video and audio between connected devices.

It also depends on what you want to connect and how good you want the picture. In many cases, even for component connections, a simple RCA (common composite) should suffice. Trying to connect it for a high-definition picture or HiFi sound may not work. Component cables’ varied plugs transfer video signals to obtain maximum quality. RCA lines lack the bandwidth to carry high-resolution signals. Simply put, these two wires are similar but not identical. A good picture requires a good component wire. RCA wires lack the bandwidth to transport HD signals.

#3. Can HDMI be converted to RCA?

HDMI cables are now widely used to connect devices to monitors and TVs. However, many TVs only have RCA inputs. Thus, HDMI cables cannot be plugged in. In this instance, an HDMI to RCA converter is required. This gadget receives the HDMI signal and sends it to the TV via RCA cable. In this case, the connector depends on the HDMI output. You can get one with the component, S Video, and classic RCA outputs. Connect the connector to a power source, then connect the HDMI cable to the connector’s HDMI port. Simply attach the RCA wire to the TV’s connector. You can connect the audio and video lines to the TV.

Many recent devices support both HDMI and RCA, so you should be able to connect with either. However, some older TVs only have RCA. You can either buy a separate RCA cable or convert your existing HDMI. Buying an RCA cable would be cheaper than the connection.

#4. Are RCA cables the same as coaxial digital?

A Coaxial digital cable resembles an RCA cable; however, it transfers digital data instead of analog. They feature thicker insulation than digital cables and resemble RCA cables due to the end connections. This wire transmits electrical signals and is shielded by aluminum foil. The cost of Coaxial digital is also different from an RCA cable used with televisions. These cables are more expensive due to the higher insulation and shielding. They can cost over $10 for a cable that would cost less than $5 for an RCA cable.

An RCA cable can replace a coaxial digital cable, although it is not advised. The digital cable has stronger shielding and better bandwidth than an RCA cable. This is why RCA cable loses signal quality over time. It may work for short distances, but for longer distances, digital coaxial is better. The digit bits are not consistent over long distances with RCA, and the sound stutters. The digital coaxial cable has all channels in one line, unlike typical RCA cables. A single wire carries both left and right signals.

Final Words
