本系统是一个设计较完善的家用全数字功率放大器。它采用了美国APOGEE公司最新的DDX直接数字放大技术，音质直逼高档模拟放大器，同时，为了扩大使用范围，系统进一步集成了模拟音频输入通道，便于没有数字音频信号的用户使用该系统。操作方面采用了大型的128*64点阵液晶显示模块和非常方便易用的旋转编码器，同时更具有遥控功能。软件方面，以Atmega16单片机核心，采用了全中文菜单显示，由旋转编码器和遥控器作为输入设备，旋转编码器和遥控器均可实现全功能的操作。-This system is a better designed home all-digital power amplifier. It uses the U.S. APOGEE" s latest DDX Direct Digital Amplification technology, sound quality almost equal to high-end analog amplifiers at the same time, in order to expand the scope of application, the system further integrates the analog audio input channels, there is no digital audio signals to facilitate users of the system. Operational use of a large 128* 64 dot matrix LCD display module and very easy to use rotary encoder, but also has a remote control function. Software, in order to Atmega16 microcontroller core, which features a full Chinese menu display by the rotary encoder and remote control as input device, rotary encoders and remote controls can achieve a fully functional operati
