Audio visual equipment is commonly used in cinema, live performances, on television, or as part of a presentation. Audiovisual equipment encompasses many different items that have been designed for specific purposes. Some audiovisual equipment may be considered primary, while others are extremely complicated.
Audio equipment also refers to audiovisual devices that record, reproduce, or process sound for broadcasting, reproduction, or other audiovisual media. These include television broadcasts, theatrical productions, recorded music, recorded lectures, or conferences and conventions. The term “audiovisual” may also refer to any computer software that generates, compresses, modifies, collects, encrypts, or offers playback of data or audio. The term “audio and visual” may also be applied to a combination of computer software, hardware, non-computer software, video hardware, picture quality improvement equipment, computer software, or photographic equipment.
A large portion of AV equipment is dedicated to one function – to amplify and interpret audio. One example of this is a digital music system that contains speakers and headphones for listening to music. Some AV devices are complete with soundboards and processing equipment.
Audiovisual systems and components can vary significantly both in price and size. You will need to decide how much audiovisual equipment you require and how much your budget can afford.
Digital audio workstations or DAS (Digital Audio Service) provide a very cost-effective solution for smaller business or home studios. These units allow users to make use of their computers as an amplifier and as a monitor. This will enable users to send a digital signal to a regular stereo system or a personal computer for recording. There are several types of DAS systems, including Digital Acoustic System, Digital Multi Zoneal Audio System, and Broadcast Audio System.
Audio-only sites such as live performances by professionals can benefit greatly from audiovisual equipment. It makes it possible to provide real-time audiovisual content to audiences, thus increasing audience participation and enhancing the event’s production value. DAS systems can also improve image quality in film and television productions, allowing directors to create a more lifelike and realistic set design. Besides, DAS equipment can also output digital sound through microphones and speakers on stage or at home.
Another application of audio and visual technology is in the arena of advertising. Audio and visual displays are familiar sights in shopping malls, airports, subways, and other public areas, and the displays usually contain video walls or video screens. They display commercials or product demonstrations and then project the images on a large projection screen. Many of these screens are attached to buildings to be viewed even when the building is closed.
