位于美国德州AUSTIN的一家初创公司D2AUDIO采用DSP核心技术解决了大功率数字功放难题。该公司专门开发的DSP芯片利用反馈机制对输出级电路进行实时调整和补偿,从而使音质接近模拟电路的水平。采用数字功放的好处很多:随着数字音源越来越多,采用数字功率放大可以省掉前级的数模转换电路,从而消除数模转换带来的失真,同时前级电路的
D2AUDIO, a startup based in AUSTIN, Texas, uses DSP core technology to solve the challenges of high-power digital power amplifiers. The company specifically developed DSP chip feedback circuit using real-time output-level circuit to adjust and compensate, so that the sound quality close to the level of analog circuits. Advantages of using digital power amplifier: With the increasing number of digital audio sources, the use of digital power amplifier can save the previous stage digital-analog conversion circuit, thereby eliminating the distortion caused by the digital-to-analog conversion, while the front-end circuit
