摘　　要：数字音频技术是今后的发展方向,纯模拟技术的音响设备必将退出历史舞台。基于音频功率放大器的模拟、数字和数字附加模拟入口的三大类型,阐述了三者的界定要点,预测数字附加模拟入口的音频功率放大器将成为专业音响设备的主流。Digital audio technology is the future development tendency, and pure analog audio equipment must be in the museum. Under this trend, the audio power amplifier was divided into three types of simulation, digital and digital additional simulation entrance, the main definition points of the three were expounded, and the third class is expected to become the mainstream of non-professional audio equipment.
