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。

PT2323 is a 6-Channel Audio Selector utilizing CMOS Technology specially designed for Home
Theater System. It provides a built-in 2-Channel to 6-Channel Translator, which can directly mix
traditional stereo channel to simulate a 6-Channel audio output. Single power supply (9V), I2C Bus
Interface as well as very low Total Harmonic Distortion (THD < 0.005 ) and other features are
incorporated into a single chip thereby providing very high performance. Pin assignments and
application circuit are optimized for easy PCB layout and cost saving advantages.

Description: This is my second 5.1 remote kit project. I have included four sections in this project. First one is a pre-amp, the second one is a controller, the third one is a power supply unit and the forth one is power out relay. I drew the all circuits by hand with a CD marker on the copper clad board.
Features
Power ON/OFF switch
Mute switch
Input switch
USB input (for Stereo Audio player)
AUX input
DVD input (5.1-channel)
Master volume: 0 to 50
6-channels volume: -10 to 10
Surround ON/OFF
Speaker mode: 5.1/2.1
All reset
Remote control
Pre-amp
The pre-amp consists of two ICs. Those are PT2323(SOP) and PT2258(DIP). It has two stereo inputs and one six-channel (5.1-channel) input. Two stereo inputs are USB and AUX. You can connect 5V stereo audio player to the USB input. I have provided the 5v ON/OFF power for this. Six-channel input is DVD.
Controller
I used to atmega328p for the controlling section. It programmed with Arduino UNO. By the end of this post you should be able to copy the code.
Used push buttons for Power ON/OFF, Mute/Unmute and Input selection. Rotary encoder for volume up/down and channel/menu select. Long press the rotary encoder's switch for the menu function. It has two power controller. First one is AMP POWER. This is for Power ON/OFF. Second one is USB POWER. This is for USB input.

Description: 5.1 Control board project for sound system. Remote control, LCD, Encoder. I have almost no application with Arduino, I always tried to use Arduino alternatives and somehow found circuit solutions. But audio applications always intrigue me. I applied the digital volume control Arduino project made with Arduino Nano PT2323 and PT2322 audio control ICs, the circuit worked very well, and it is very good that it is remote control controlled, in addition, all controls can be made with a button encoder and 2 buttons.
