The power amplifier adopts multi loop control technology and has excellent technical indicators, especially for power amplification
technology under low impedance and high current working conditions, which enables the power amplifier to have an efficiency of over
95% and excellent stability; The switching power supply adopts active PFC and soft switching technology, and has been optimized for
audio power amplifiers, which can adapt to harsh power grid environments and provide continuous surging power for the amplifiers. This
series of amplifiers has the characteristics of high reliability, sufficient power, outstanding sound quality, and strong adaptability. Each
channel can independently choose to drive a constant voltage or constant resistance speaker, perfectly suitable for various fixed
installation projects.
