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、6声道独立控制
3、静音
4、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
3、声道信息-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
