AC-2500 Power Amplifier AC series power amplifiers have unique appearance, durable structure, and lower noise. Regardless of power output or efficiency and timber, AC series have outstanding performance, thus being suitable for high-demanding fixed installation and touring shows. AC series power amplifiers apply high-power transformer and high-efficient circuit, enabling the products to protect circuit and provide customers with safety and reliability. For example, as for overheat protection, when the temperature reaches 85℃, the loudspeaker will cut off output automatically, and when the temperature is lower than 65℃, the loudspeaker will restore output automatically; as for over-current protection, the loudspeaker will be damaged in the event of output disconnection or low impedance; as for drift protection, when the loudspeaker outputs direct current, it will cut off the connection with the enclosure automatically in the event that it might be damaged.
