研制一套以单片机ＰＩＣ１６Ｃ５４为核心的专业音频功率放大器控制系统。根据所检测的负载阻抗大小自动选择工作电压，提高了放大器对扬声器系统的适应性；在负载阻抗过小时的强制关机，增强了功率放大器的使用安全性。
Development of a set of PIC16C54 microcontroller as the core of professional audio power amplifier control system. According to the detected load impedance of the size of the automatic selection of the operating voltage, the amplifier to improve the speaker system adaptability; load impedance is too small forced shutdown, enhanced power amplifier safety.
