Although we often trip over them, audio and video cables have become an important part of our lives. Audio and video cables are considered the backbone of our highly modern world. In fact, we require appropriate sound and sight in every setting. Typically, cables incorporate two or more wires that are twisted or bound together to produce an electric current.

Cables that are capable of transmitting both audio and video signals are known as audiovisual cables. Here, we are going to explore the different types of cables that can transmit video data only, cables that can transmit audio data only, as well as cables that can transmit both.

Different Types of Audio-Only Cables

3.5mm Cables

Considered one of the most popular audio cables on the market, 3.5mm cables are commonly used for connecting headphones to devices, earning them the nickname “headphone jacks.”

Typically suitable for ports found on phones, television sets, and computers, these cables come in different versions – TS, TRRS, and TRS. The TRS variant features two rings, providing three conductors, making it ideal for stereo connections such as speakers. Meanwhile, the TRRS variant includes three rings and four conductors, perfect for a mono mic and stereo audio.

2.5mm Cables

Smaller than their 3.5mm counterparts, 2.5mm cables serve the same functions. The only difference lies in their size. Like 3.5mm cables, 2.5mm cables come in three categories: TS, TRRS, and TRS versions. These are typically used with 2.5mm ports, commonly found on phones, but are also increasingly used with cordless home phones and radios.

Optical Toslink Cables

Ideal for your at-home audio devices, Optical Toslink cables are made of fiber optic cables specifically designed for audio devices. Signals are transformed into lasers, travel through the cable, and then converted back into audio.

Most modern television sets include ports for optical cables. These cables provide a digital signal that produces clear and crisp audio. However, they have a drawback: the signal can only travel a maximum distance of 5 meters; beyond that, it weakens and may not function at all. An extender is the best solution to this problem.

¼” Cables

Considered the original version, similar to 3.5mm cables, while 2.5mm cables are the downsized versions. In the case of 1⁄4” cables, they are the scaled-up versions, featuring TS, TRS, and TRRS variants.

The difference lies in their larger size and heavier-duty construction, using larger plugs. Typically used in professional audio equipment such as speakers, amplifiers, and various musical instruments, they are sometimes referred to as “instrument jacks” or “guitar jacks.”

XLR Cables

Also designed for professional audio equipment, XLR cables come in various versions distinguished by the number of pins or holes within the connector. The 3-pin version is one of the most popular. XLR connectors can have a maximum of seven pins. While both XLR cables and 1⁄4” cables are used in some professional audio equipment, microphones and mixers typically use XLR cables rather than 1⁄4” cables.

MIDI Cables

MIDI (Musical Instrument Digital Interface) cables resemble 5-pin XLR cables, with the difference being that MIDI cables come with 5-pin DIN connectors. These cables are primarily designed for connecting musical devices to computers, transmitting audio signals as data signals. However, they are not limited to audio; they can also transmit information such as patch data.

SpeakOn Cables

SpeakOn Cables represents the latest type of cable available in the market. These cables serve the same purpose as XLR cables and ¼” cables and are typically used in loudspeakers. Engineered to carry large amounts of power, they are ideal for heavy-duty amplifiers. Equipped with metal contacts embedded within the connector, they are safe to use, eliminating concerns about electrocution. Additionally, they feature a locking mechanism for secure connections.

What are the Different Types of Video-Only Cables?

S-Video Cables

Nowadays, S-Video cables are considered outdated. While they are rarely used with new devices, they are still commonly found with older equipment. Although old TV sets and VCRs are no longer prevalent, as long as they are still in use, S-Video cables will remain relevant.

DB9 Series Cables

The DB9 Series cables are another type of outdated video connection cable. Typically used in computers, especially with computer monitors, these cables have largely been replaced by VGA over the years. While DB9 Series cables can also transmit data signals, they have largely been supplanted by USB. However, some older computers may still utilize DB9 connections.

SVGA Cables

SVGA (Super Video Graphics Array) cables represent an upgraded version of the standard VGA. They offer higher resolution and support for more colors compared to VGA. Sometimes referred to as Ultra VGA or Enhanced VGA, SVGA cables provide improved graphical output.

HDMI to DVI Adaptors

Commonly, HDMI to DVI Adaptors are used for remodeling DVI output from computers or any other devices towards television sets or projectors.

Different Types of Audio-Visual Cables

HDMI (High Definition Multimedia Interface) Cables

HDMI cables are compact connectors capable of transmitting compressed or uncompressed audio as well as uncompressed video data. They adhere to the EIA/CEA-861 standards, which specify the waveforms and video formats for transmitting uncompressed and compressed audio and auxiliary data. HDMI cables were first introduced in 2002 and have since become common in usage.

RCA Connectors

RCA cables are often color-coded – black or white represents the left channel, red signifies the right channel of stereo audio, while yellow is used for composite video. Typically, this type of cable is composed of an RF coaxial created during the early 1940s. These cables are designed for transmitting audio and visual signals, hence they are sometimes referred to as “A/V” jacks. Additionally, they can also serve as connectors for loudspeakers or as power connectors.

Coaxial Cables

Coaxial cables consist of an insulating tubular layer surrounding an inner conductor. This cable design was patented in 1880. With customized dimensions, coaxial cables provide a continuous conductor layer, functioning as a medium for radio frequency transmission.

Cable Modem

Think of it as a type of Network Bridge that offers bidirectional data transmission through radio frequency channels. A cable modem is commonly used to provide broadband internet access. This is made possible because of the range of high bandwidth of vital networks, which are the (RFOG) and Hybrid Fiber Coaxial channel (HFC).

F Connectors

This particular connector was designed way back in the early 1950s. And since then, it has been utilized for terrestrial and satellite TVs, particularly, for TV antennae. F Connectors have an enormous bandwidth as well as an impedance match of 75 Ohms. It is designed for domestic terrestrial cables anterior.

SCART

This 21-pin connector is vital for the connection of AV equipment. CENELEC is recognized as the standard for SCART. Most often, it is known as the IEC 9331-1 standard. Its main purpose is to transmit analog standard-definition content. Typically, they are capable of transmitting composite and stereo, ROB video, digital, and audio signals.

As a conclusion, it would be more appropriate if you will first determine the exact use. You can either choose coaxial cables, HDMI cables, and cable modems since they are highly advanced when it comes to signal transmission and there is minimal loss of power.
