Audio Visual System (AV): Major Components And How They Work

 Audio discussions

“Having a superb quality yet high impact audio visual system is crucial in leaving a lasting message to your spectator’s sight and hearing” (Executive PA Media, 2017).

Audio Visual (AV) is electronic media possessing both sound and visual components, such as presentations, filmstelevision programs, corporate conferencing, church services, and live theatre productions.

Audiovisual service providers frequently offer web streaming, video conferencing, and live broadcast services. 

Computer-based audiovisual equipment is often used in education, with many schools and universities installing projection equipment and using interactive whiteboard technology to facilitate the delivery of messages.

This article will look into the types of audio-visual systems, major components and equipment that are widely used in recent years and discuss the technology behind, usage, importance and how much it cost.

What is an AV control system?

Audio Visual Control System is the brain that does the collection and communication between hardware and software that allows the operator to control each piece in tandem or individually. 

It is a real multi-tasking tool that functions to streamline various commands that control the individual technology. When it comes to audiovisual system integration, knowing about your AV system is important as it helps to deliver a successful event. 

Types of Audio Visual Systems

Portable audio-visual system

Portable AV systems are equipment that is small and easy to carry. It is suited for small scale events and acts as a voice amplifier. To make an office or mobile presentation more effective, a portable audio-visual system always comes to the presenter’s mind. 

Portable AV system equipment is as mentioned below:

  • Projector 
  • Projector Screen (tripod or foldable frame type)
  • Microphones
  • Portable PA (public announcement) System or Powered Portable Speaker   
  • Slide changer (pointer)


Wireless audio-visual system

Wireless AV system refers to a connection or communication of the audiovisual system seamlessly without a jungle of cables or wires to transmit signals between equipment and controller. 

All equipment like projector, LED screen, digital signage, speaker, and others to connect a controller (hardware) and programme (software) is a part of a wireless AV system. 

A user just needs to turn on the power supply and control the entire AV system seamlessly. 

Examples of wireless audiovisual systems would be Bluetooth speakers, Radio FM transmitters, or even TV.

Interactive audio-visual system 

An interactive audiovisual system is one that is responsive to human commands by voice or touch. It can be used to control settings for AV equipment like speakers, TVs and lighting. It is common for household usage. 

One of the most common interactive AV systems is the touch screen, which can interact and respond with people. 

Another use is demonstrated in touch screens in shopping malls directory, fast food outlets self-order system,  and digital display for exhibitions that get people to interact and get information from it. 

Google home system is another system that can interact with voice and command, where you can control your household electric appliances like TV, lightings and etc upon commanding the action. 

Audiovisual system for conference room 

Having a well-equipped audio-visual system for the conference room is important, not only to make meetings smarter but also to maximize productivity and efficiency of work among employees. 

As more meetings are conducted virtually across the globe, a state-of-art conference room system with an effective audiovisual setup needs to be built for future businesses. 

There are 8 ways to boost productivity through conference room AV design:

Audio Visual Equipment 

Cameras and displays

Cameras play an important role in video conferencing solutions and in events (especially virtual events). 

It allows two or more people to communicate with each other in real-time. A good camera will help participants to view and join the conversation, sharing information (documents and presentation) during the call. 

The key to having a good visual is to have a good angle. We need to take appropriate height, viewing distance and angle into consideration that provides the best output for participants. 

There are few types of cameras available in the market to fit your need. 

Events and virtual events can consider using Pan-Tilt-Zoom (PTZ) camera and HD or Full HD video camera. PTZ camera, fixed camera and document camera are more suitable for video conference systems for meeting rooms and classroom settings.

Displays or monitors are the focal points of every video meeting and event. It is positioned in the meeting or event space that display the best views for both speaker and audiences. 

There are various types of displays we can take into consideration.

  • TVs 
  • Interactive display
  • Flat display
  • LED screen
  • Multi-monitor display
  • Video wall display
  • Broadcast video monitors

LED panels 

The better the sound quality, the better the image quality should be in parallel. The most commonly used display in audiovisual systems is LED display technology. LED panels/ screens provide saturated colors due to LED lights. 

LED Screen Panel

LED screen can be adapted to the desired measurements (sizes) and areas. The quality of the image will not be affected whether is indoor or outdoor as long as the right type of LED is chosen. 

LED panels operate with lower energy compared with other display types. Having high-quality images and low energy requirement makes it possible to use them everywhere. 

You can use LED panels for:

  • Concerts (indoor and outdoor)
  • Stadiums
  • Outdoor advertising
  • Shopping Centre
  • Hotels
  • Event venues

Projectors 

A projector or video projector is an electronic device that takes input audio/ visual signals and outputs video onto any flat surface, which is most often a white or silver-coloured projector screen. 

A projector is a nice piece of AV equipment to have for events where many people will be watching the same thing at the same time. 

You can project your computer screen onto a large surface or screen easily with a projector and then you can rest easy knowing that no one has to strain to see.

There are different types of projectors:

    1. Cathode Ray Tube (CRT)- uses lenses to project the images
    2. Liquid Crystal Display (LCD)- uses liquid crystals to project images
    3. Digital Light Processing (DLP)- uses micro-mirrors to project images
    4. Laser Projector – lasers only create the exact colors needed and uses less power

Projectors are often used in: 

  • Classroom
  • Meeting rooms
  • Office
  • Home 
  • Event 

Projection mapping is also an interesting way to communicate your message to your audience. It can be as simple as indoor stage effects or as complex as video onto buildings and industrial landscapes. 

The purpose of projection mapping in events is to provide a more engaging experience for attendees, through visual stimulation. 

The technology is used to manipulate lighting onto varying surface types and turn common objects into interactive, 3D displays.

Speakers

A good speaker system can make all the difference at an event without you knowing. The last thing you want is for people to have a hard time listening to you or your presenters. So having a good quality speaker system in place is essential. 

What do you need to consider before deciding which speaker system is suitable for your event? 

There are few important factors:

  • Size of venue
  • Audience size
  • Usage of the speaker (speech, concert, background music and etc)

Types of speakers:

  • Tower / Floor Standing Speaker
  • Line Array Speakers
  • Bookshelf Speaker
  • Surround Speaker / Satellite Speaker
  • Centre-Channel Speaker
  • Subwoofers
  • Soundbars
  • Build-in Speaker
  • In-wall Speakers
  • In-ceiling Speakers 
  • Outdoor Speakers

Microphones

Giving a speech or presentation? Or just need a way to get your audience’s attention? 

Then a microphone is a must-have! 

It may not be the most high-end spec, but the quality should be good enough to withstand use over the period of your event and should be easy to connect to speakers or receiver equipment.

There are 4 basic types of microphones:

    1. Dynamic Microphones – They are affordable, durable, and sound fantastic on some of the most common recordings. Shure SM57 is one of the common dynamic microphones that is suitable for speeches and recording.
    2. Large Diaphragm Condenser Microphone – they are large, stylish and serious-looking mics that you see in professional recording situations. They are much more sensitive than a dynamic mic and ribbon mics. It is suitable for vocals.
    3. Small Diaphragm Condenser Microphone (pencil condenser) – they have a great transient response, extended top end, and consistent pickup patterns. They are great for realistic stereo techniques and acoustic instruments. 
    4. Ribbon Microphones – uses ultra-thin ribbon of electro-conductive material suspended between the poles of a magnet to generate signals. But for some, their sound is worth the trade for its durability. Ribbon mics are prized for their warm, vintage tone. Suitable for sources like guitar amps, drum overheads or brass.

Microphone choices are probably the most important factor after the quality of your instrument itself.

Laptop or Desktop Computer

The not to missed out AV equipment will be laptop or desktop computer. It helps to hold and any information you want to present to your audience. 

Whether it is a slideshow for a wedding, a presentation for a meeting or conference, or music for a dance, you need to have a computer that’s ready and loaded with your audio or visual files. 

You can use a laptop for easy transportation or a desktop computer for a more permanent location. Desktop computers are widely used for a virtual event because it supports heavy files and more stable in processing data.

Lighting equipment 

Lighting equipment is an important part of visual needs. Suitable lighting design for the room size and its function are as important as other audiovisual equipment. From theatrical lighting to presentation and meeting rooms, we got our professional team to design the best setting.

Speak to your AV partner and lighting designer regarding your purpose. Let them make sure all equipment and programming fit your ideal outcome and objective. No matter what content your event has on stage, if the audience can’t see it, it will be wasted. 

Why is an AV control system important for a virtual event?

Due to the COVID-19 pandemic, live events are currently impossible and audiences are restricted to attend it in-person too. 

It is unquestionable that there are more virtual events now than ever before. 

With that being said, the virtual experiences, speaker experiences, audience experiences are raised to a higher standard. 

Hence, it falls onto audiovisual equipment and systems integrated to work together seamlessly that are managed, and controlled by an AV control system. 

With an AV control system, we can take a virtual event to next level as all the equipment are being controlled in one central device, access and control can be automated or run manually. 

Therefore, IT downtime is reduced. 

Plus, technical onboarding time for both- the speaker and participants of the virtual event are greatly reduced. Consequently, hosting the virtual event at ease and yet increasing user satisfaction effectively and efficiently. 

How does an audiovisual system work?

Audiovisual integration stands for the combination of audio and visual equipment to make a better viewing and listening experience during meetings or events. 

Various pieces of equipment are used to achieve the very best communication for large meetings or events so that no one is left out and all goals and needs are met. 

Based on the equipment list of audiovisuals mentioned above, the combination of these modern pieces of equipment turns into a seamless viewing and listening experience for users. 

Each of these elements offers a different service that, when brought together, creates the perfect mix of sound and vision for your audience.

It begins with the process of having a team of audio-visual system experts recommend and come up with an audiovisual design that matches your needs. 

Moving on with audiovisual system installation, the technicians are responsible for it as well as continuous monitoring throughout the event to make sure the whole event go through in a seamless manner. 

Every device can be controlled and monitored in the room or space from one interface – typically a touch screen or a keypad – effectively removing the need for a stack of remote controls and a jungle of cables in the room.
