A Booster Amplifier is a high-power audio amplifier used in public address systems to increase output power and extend speaker coverage. Booster amplifiers are typically added when the existing PA amplifier capacity is insufficient or when large areas require higher sound pressure levels. They are commonly used in factories, warehouses, campuses, railway stations, airports, malls, and industrial facilities.
Compatible with 100V/70V line speaker systems, booster amplifiers ensure consistent audio performance over long cable distances without signal loss. Modern booster amplifiers support features such as overload protection, thermal protection, balanced inputs, and integration with voice alarm and emergency paging systems. Available in various power ratings, booster amplifiers provide a reliable solution for expanding PA system performance and scalability.
