[SCMvolcontrol

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。 -err
