● Pulse Width Modulation (PWM) technology that achieves an amplifier efficiency of over 80%. By using multiple MOSFETs in parallel, we offer a 50% increase in surge resistance compared to single MOSFETs used by competitors, making it ideal for driving 2-ohm speakers in line array systems under low load conditions. 
● Power Factor Correction (FPC) technology with an efficiency of 92%, capable of stable operation across a wide voltage range of 90V-260V. The 650V/100A automotive-grade IGBT full-bridge circuit saves 40% on power consumption and reduces the size of power cable conductors. 
● The audio circuitry features HIFI-grade components, including American National Semiconductor op-amps, Japanese TDK ferrite beads, Korean SAMWHA aluminum electrolytic capacitors, and American IXYS super junction MOSFETs, delivering rich and elastic sound quality with clear and detailed high, middle, and low frequencies. 
● Stringent quality control in production, with 8 inspection and testing processes, including low-load long-term aging. Each amplifier is AP audio tested to ensure qualified parameters before leaving the factory, ensuring durability and reliability in various environments.
