| 本文介绍了一种新型功率放大电路的设计，利用普通元器件自制杜比环绕声解码器，将直流控制技术应用到前置放大电路，将有源伺服技术应用到超重低音电路，各具特色，LM3886功率放大芯片，功率大，效果好。 |
| 英文摘要: |
| In this paper, the design of a new type of power-amplified circuit is presented.The design includes personally fabricating Dupi surrounding voice decipherer by using ordinary electronic devices, using DC control technology in the predrive amplified circuit and applying active servo-technology to the over-loaded low voice curcuit. Doing each of all this has its own characteristics. Also used in the design is the LM 3886 power amplification chip, which is both potent and efficient. |
