A PA system, or Public Address System, doesn’t have a specific voltage as it can vary depending on the system’s design and the application. However, it’s common for PA systems to use transformers and amplifiers to increase the initial signal voltage from microphones, which are typically around 1V, to hundreds or even thousands of volts to drive the speakers. The specific voltage would depend on the amplifier’s power output and the speaker’s impedance. Always ensure safety when handling such equipment, as high voltages can be dangerous.
