Description: 近段时间闲来无事做了一款AV和HI-FI两用的前级，采用音量音调处理芯片PT2322完成音量音调的处理，支持六声道音量0~15分贝可调，高中低音支持-7db~+7db可调，总音量支持0~79分贝可调，步进为2分贝每次，并且具有静音、3D和直通功能，不论是在听音乐还是在看电影两不误；采用pt2323实现音源输入选择和2声道转换成6声道的功能，支持四组普通立体声输入和一组DVD六声道输入，并且能够将四组立体声其中的任何一组转换成六声道，即使是用VCD看普通碟片时也能欣赏到有如DVD一样的环绕音效。由于PT2323和PT2322支持I2C总线控制，利用89c51对其进行控制，PCB板连线方便，控制简单。本板除了以上功能外，还特留有一个输出口，用来控制后面所接的功率放大模块的电源的关断，以实现遥控开关机，静音时也将功率放大模块的电源模块关断，以实现节能的目的。本电路还有一个重要特点，整个电路采用单5V电源供电，接口简单，连线方便，便入摩机用。人对电路操作主要有两种方式，一是通过键盘来进行控制，二是通过配有的红处的遥控接收头来控制，遥控器可选市面上很容易买到的由TC9148型的遥控器即可。本人提供少量PCB板，供爱好音响和单片机的同行做实验，
如有需要也可提供全套散件或成品板。

Description: ICCAVR下的红外解码程序，全部源码，原理图和PCB，芯片资料,一个可实际运行的例子，使用网上邮购的TL038BD接收管，测试过电视机遥控器、DVD遥控器，发现遥控器基本上都兼容uPD6121的.
环境使用ICCAVR6.31A，MEGA8L，内部RC8M。
压缩包中upd6121.pdf和S0101.Zip是红外遥控芯片资料，LYJ_DDB是Protel99SE下的，其它是源程序。-the infrared decoding programm under ICCAVR environment, with all the source code, schematic and PCB, chip data, use theTL038BD receiving tubes, tested the TV remote control, DVD remote control, found that almost all the remote control compatible uPD6121. environmentICCAVR6.31A, MEGA8L, internal RC8M. Compressed package upd6121.pdf and S0101.Zip is infrared remote control chip data, LYJ_DDB is under Protel99SE other is the source.
