What Is AV?

AV, or Audio-Visual, is a term used to describe the combination of sound and visual elements that are used to create an immersive experience for the viewer. AV can be found in a variety of settings from primary schools to corporate boardrooms, enhancing experiences of users and the audience. As an experienced AV installer, we’ve seen a host of innovative developments over the last few decades and the history of audio visual technology is no less fascinating. 

So, in this blog post, we will explore the basics of AV, including its history, its components and its uses. 

The History of AV

The history of AV can be traced back to the early 20th century, when the first motion pictures were being produced. At that time, movies were silent, and the only way to experience them was through visual images. However, as technology progressed, sound was added to movies, and the first “talkies” were born.

Over the years, AV technology to evolve, with the introduction of colour, surround sound, and other innovations. Today, AV is used in a wide range of applications, from enhancing collaboration in business to providing interactive shopping experiences.


The components of AV

AV systems are made up of a variety of components, each of which plays an important role in creating an immersive experience for the viewer. Some of the key components of an AV system include:

Display Devices

Display devices are used to show visual images to the viewer. These can include digital signage screens, projectors, large format displays and video walls. The quality of the display device is an important factor in the overall quality of the AV experience. For example, the content playing on a retail digital signage screen needs to be clear and easy to read even in direct sunlight, so choosing the right display is essential.

Audio Devices

Audio devices are used to provide sound to the viewer. These can include PA systems, speakers, microphones and soundbars. Like display devices, the quality of the audio device is an important factor because if your meeting audience can’t hear you clearly then your all-important sales pitch won’t have the desired impact.

Source Devices

Source devices are used to provide the content that is being displayed and heard. These can include a video conferencing computer, digital signage player and wireless presentation devices. Choosing a high quality source device is important for content to have a professional look and feel by ensuring it is broadcast seamlessly, in HD, without lagging.


Cables and connectors

Cables and connectors are used to connect the various components of the AV system together. These can include HDMI cables and CAT-5 cables which allow your audio-visual devices to perform optimally.

Control Systems

Audio visual devices are operated by AV control systems. These include software and hardware controllers with easy-to-use touch panel interfaces. A control system which is user friendly ensures the AV devices are used effectively and can result in a significantly enhanced experience.

The uses of AV

AV technology is used in a wide range of applications, from corporate presentations to school productions. Some of the key uses of AV include:


AV technology in a retail setting provides a way for high street businesses to compete with online retailers through the use of experiential marketing. Augmented and virtual reality technology can be combined with instore shopping to provide a unique shopping experience.

AV technology in healthcare enables medical professionals to deliver efficient and effective patient care making it a crucial element in the support of healthcare staff. From digital signage in waiting rooms which provide useful information while reducing perceived waiting times, to video conferencing technology which offers an online alternative to connecting with patients when a face to face meeting isn’t possible.

Sports Centres & Gyms

AV technology is commonly used in leisure centres and gyms where digital displays can be found in weights rooms, while music plays an important part in creating atmosphere and providing a motivating soundtrack to an exercise class. As well as the flexibility provided by creating audio zones in each area of the building, gym sound systems feature MP3 playback, Bluetooth connectivity and DAB radio, providing a variety of options for staff and trainers to deliver the best possible customer experience.

Corporate Presentations

AV technology is also commonly used in corporate environments, where it is used to create engaging presentations for employees, clients, and stakeholders. In these settings, AV technology can be used to display slideshows, videos, and other multimedia content. Wireless presentation systems have become a popular tool for companies looking to improve the ease and speed of presenting and sharing content within a meeting.

In office settings, room booking displays offer greater control and use of collaboration spaces by providing live updates of room availability, insights into room usage, and the ability to spontaneously book a meeting.



AV technology has helped warehouse to revolutionise the way workers communicate with the wider business through the use of digital signage and high quality sound systems. 

Visual examples include displaying live data relating to outstanding orders on digital screens, as well as showing logistics information and despatch status of goods. While warehouse audio systems can improve the working environment with background music, emergency message broadcasts and quick and easy communication across the workforce.


Schools and universities can also benefit greatly from educational AV technology, where it is used to create engaging and interactive learning experiences for students. In classrooms, AV technology can be used to display educational videos, interactive simulations, and other multimedia content, while digital signage screens positioned strategically around the building provides schedule and wayfinding information for students and visitors.
