技术概述 “直接数字放大”（Direct Digital Amplification,DDX）是一个高效的全数字放大器专利体系结构,是为满足从PC多媒体到家庭音响系统乃至MP3重放设备的各种音响的应用需求而开发。 今天,大多数自称是数字化的娱乐系统,都是利用模拟放大器来增强数模转换器（DAC）产生的模拟信号,而DDX技术则采用一项数字信号处理专利技术取代DAC,以数字方式控制高效的功率设备。这种方法允许直接连接数字音源,避免了模拟信号被破坏,而且,放大器效率比模
Technical Overview Direct Digital Amplification (DDX) is a patented, all-digital, high-efficiency amplifier architecture developed to meet the needs of a variety of audio applications, from PC multimedia to home audio systems and even to MP3 playback devices. Today, most digital entertainment systems claim to use analog amplifiers to boost analog signals generated by digital-to-analog converters (DACs), while DDX technology uses a patented digital signal processing technology to replace DACs to digitally control efficiency Power equipment. This method allows direct connection to the digital audio source, avoids the analog signal is destroyed, and, the efficiency of the amplifier than the analog
