Public Address audio (PA system) is a constant-voltage sound reinforcement system designed specifically for public spaces. It integrates three core functions: background music, service announcement, and emergency broadcast, with key goals of wide and even coverage, clear speech intelligibility, and fire safety priority. Guangzhou Skytone Audio has been deeply engaged in this field for many years, providing complete public address solutions from power amplifiers to terminal speakers.

I. System Core and Skytone Technologies

Public address systems adopt 70V/100V constant-voltage transmission, supporting long-distance cabling and parallel connection of multiple loudspeakers, suitable for shopping malls, schools, industrial parks and other scenarios. Skytone’s flagship products include constant-voltage power amplifiers, ceiling speakers, wall-mounted speakers and outdoor column speakers, such as the 400T/500T metal ceiling speakers and 3-inch conference column speakers, balancing sound quality and stability. Its power amplifiers support stable operation under wide voltage ranges, and loudspeakers feature IP52 protection, adapting to complex indoor and outdoor environments.
