What is VOX?
VOX, which stands for Voice Operated eXchange, is a broadcasting and audio engineering term that refers to a system or device that activates automatically when it detects an audio signal above a preset threshold. In the Indian broadcasting industry, VOX circuits are widely used in radio stations, television studios, and podcast production houses to control audio playback, switch between microphones, and manage signal routing without manual intervention. The technology works on a sound-triggered mechanism where any audio crossing a defined decibel level prompts the equipment to perform a specific function, such as starting a recording, opening a channel, or muting background noise. In India, VOX systems are commonly deployed by All India Radio, private FM channels, television newsrooms, and conference systems to streamline live broadcasts and panel discussions. The term also appears in amateur radio operations, walkie-talkie handsets, intercoms, and security surveillance setups across offices and public venues. For students preparing for technical examinations in electronics, sound engineering, or mass communication, understanding VOX technology forms part of the curriculum in audio production and broadcast engineering courses offered by institutions like FTII Pune and various polytechnics.
