Boost is the process of increasing the level, strength, or intensity of a signal, sound, or light, serving as the opposite of attenuation.
In AV and structured cabling systems, boost refers to amplifying a signal so it reaches the required performance level without degradation. In audio, boost raises overall volume or specific frequency ranges to enhance clarity. In video or lighting, it increases brightness, contrast, or intensity for improved visibility. In data and power transmission, boost strengthens signals traveling through copper or fiber to prevent loss across long distances. While boosting is essential to counteract attenuation, over-boosting can introduce distortion or noise, making precise control critical in professional environments.
Boosting itself is not directly regulated, but amplification systems may follow standards from ANSI (American National Standards Institute), IEEE (Institute of Electrical and Electronics Engineers), and IEC (International Electrotechnical Commission) to ensure performance and safety.
The concept of boost originated in early 20th-century audio engineering to amplify sound in theaters and broadcast studios. It later expanded into video, lighting, and data transmission, making “boost” a widely used term across AV, communications, and electrical systems.
