Digital Coaxial Cable and RCA are two of the most popular audio and video cables in use today. Both offer their benefits and disadvantages at different costs, so it can be challenging to choose one over another.
RCA is more commonly used for video connections, whereas digital coaxial is mainly used for audio connections. When it comes to sound quality, the digital coaxial cable is better than RCA.
In this article, we look at how RCA vs coax cables perform from a cost and quality perspective and compare them against each other.
What Is a Digital Coaxial Cable?
A digital coaxial cable is a type of cable that’s used to send digital audio and video signals. It’s much like an RCA cable, except it has thicker insulation and can carry a higher signal quality. This makes it ideal for connecting high-end audio equipment, like a receiver or amplifier.
Digital coaxial cable is a category of cable that carries digital signals over standard copper wires. The term coaxial refers to the fact this type of cable has a center conductor and an outer jacket or sheath. The center conductor is also referred to as the inner conductor or inner shield. The outer jacket or sheath is usually made from plastic but can also be made from aluminum, copper, or other metals.
Digital coaxial cables are used in many applications such as satellite TV, HDTV, video content distribution, and audio/video distribution. These cables often connect devices such as set-top boxes and DVD players to televisions and stereo systems.
Some people also use it to connect their TV to their cable box or satellite receiver. But whatever you use it for, ensure you get the correct type of connector on each end, or you’re not going to get the best results.
Digital Coaxial Cables Features
1. The principal feature of digital coaxial cables is that they have low attenuation and a low insertion loss. These cables are used to transmit data and audio and video signals. They also have a small diameter and a thin wall thickness, making them flexible and easy to install.
2. The most important characteristic of these cables is that they can carry high frequencies without any degradation in performance. The frequency range of these cables ranges from 100 MHz to 3 GHz. This means they can carry signals with very high frequencies without any loss in quality or performance.
3. Another feature of these cables is their resistance to electromagnetic interference (EMI). The EMI resistance means that there will be no breakage in signal transmission due to electromagnetic interference (EMI).
This makes digital coaxial cables ideal for use in areas with interference from other sources. These could be power lines or radio frequency signals interfered by devices such as microwave ovens or wireless routers.
4. Digital coaxial cable is also resistant to moisture, chemicals, and heat because it has thin walls, which make it flexible enough for bending around objects like pipes

What Is an RCA Cable?
An RCA cable, also known as a red-white-and-yellow cable, is the traditional type of audio cable you use to connect devices like a TV to a sound system.
RCA cables connect the analog video and audio signals from your TV, DVD player, cable box, or other home entertainment device to your home theater system. RCA cable has a male connector on one end and a female connector on the other end. The male connector is usually yellow or white in color, while the female connector is usually red or black.
The red wire in an RCA cable is for the audio signal, the white wire is for the ground, and the yellow wire is for the video signal. RCA cables are usually used to send audio and video signals between devices, but they can also be used to send data signals.
The cable is made out of two conductors, which are separated by an insulating material. This insulating material is made of rubber or plastic, depending on the RCA cable used. The conductors are usually copper or aluminum, but they can also be gold-plated or silver-plated.
The most common types of RCA cables include:
- Mono – One conductor carrying a single audio signal – this connector has one pair of pins for each channel.
- Stereo – Two conductors carrying separate audio signals – this connector has two pairs of pins for each channel.
- Surround Sound – A set of four conductors carrying separate audio signals – this connector has four pairs of pins for each channel.
RCA cables Features
RCA cables have many features that make them more versatile than standard cables with six-pin connectors. These features include:
- Shielded – This feature prevents interference from other electrical devices in your home or office.
- Foil Insulation – This insulation protects against electrical shorts caused by arcing or overheating.
- Polarized Contact – This feature reduces noise and distortion when using high-quality components on low-quality power sources.
- Gold Plated Contacts – This feature ensures that the contacts on your RCA cable are durable and will not corrode over time as cheaper versions might.
Pros and Cons of RCA Cables
Pros:
- These cables are easy to use because they can be disconnected from one another at any time without affecting their performance or functionality.
- They help protect your equipment from damage caused by static electricity build-up from power outlets or other components near it.
- The cables can be connected in any order and will still work correctly with no sound quality or functionality loss.
- RCA plugs provide higher sound quality than other audio cables such as XLR and TRS plugs. This is because they do not have as many components in their construction, leading to better clarity.
- RCA cables are less likely to have a problem with interference than other types of cable.
- RCA cables are a simple, inexpensive way to connect your speakers to your home theater system.
- They provide a reliable way to connect speakers from different brands and price levels.
