Power amplifiers are the core components of public address (PA) and professional audio systems, responsible for boosting audio signals to drive speakers with clarity and reliability. Used in offices, schools, hospitals, factories, malls, auditoriums, and large venues, power amplifiers ensure consistent sound coverage for announcements, background music, and emergency paging.

Available in 100V/70V line and low-impedance configurations, power amplifiers support efficient audio distribution over long cable distances or high-fidelity sound for performance spaces. Modern power amplifiers feature thermal and overload protection, balanced inputs, rack-mount design, and compatibility with voice alarm systems. With a wide range of power ratings—from compact models to high-output units—power amplifiers offer scalable solutions for both small installations and large, multi-zone PA systems.
