Description: 各功能描述:
1. 当A为低电平时,AC-3灯点亮,即是AC-3的输入方式 当A为高电平时,STEREO灯点亮,即是STEREO的输入方式
2. 当STANDBY灯点亮时，为待机状态；此LED闪动时为MUTE状态,PT2258为静音状态,同时STANDBY为低电平
3. 各声道（FRONT，SUB，REAR，CENT）其微调音量调节+/-5dB；音量调节从01~80dB
4. 面板无任何按键,均为遥控器控制
5. 刚开机时为待机状态，开机时音量为50dB状态,各微调为0dB,
6. 按遥控器的REST键后,系统为开机时状态，
7. PT2258音量衰减共80DB,按遥控器每按一次衰减1dB,
-Description of each function: 1. When A low when, AC-3 lights lit, that is, AC-3 input mode when A is high when, STEREO lights lit, that is, STEREO input 2. When the STANDBY lamp lit, for standby mode this LED flashing when the MUTE state, PT2258 for the mute state, at the same time STANDBY low 3. the channel (FRONT, SUB, REAR, CENT) fine tuning to adjust the volume of its+ /-5dB adjust the volume from 01 ~ 80dB4. panel without any keys are remote control 5. just machines for the standby mode, the boot volume to 50dB, and the fine-tuning for 0dB, 6. by remote REST button, the system for boot-up status, 7.

Description: 开发环境 KEIL
PT2258前级音量控制板
6声道，每声道可独立控制，0dB到-79dB衰减
电子音量控制可以解决普通机械式电位器调节音量时的噪音，声道不可独立控制，集成遥控复杂，马达电位器难控制，二次开发困难等问题
主芯片：STC89C52RC，PT2258，AT24C02
主要功能： 1、6声道同时控制
2、静音
3、开机恢复关机时音量数值
LED显示内容： 1、音量数值
2、静音信息-Pre-development environment KEIL PT2258 6-channel volume control panel, each channel can be independently controlled, 0dB to-79dB attenuation electronic volume control can solve the ordinary mechanical potentiometer to adjust the volume when the noise is not independent channel control, integrated remote control complex , motor potentiometer difficult to control, difficult issues such as the secondary development of the main chip: STC89C52RC, PT2258, AT24C02 main functions: 2,6 1,6 channels simultaneously control 3-channel independent control, mute 4, when turn off the volume to restore the value LED display: 1, value 2 volume, mute information 3, channel information
