已经更新7294 3886的板子都已经实际试过 噪声很小
1875 4766/1876的没有试过
其中7293 94系列 正负电源一定要同时接上 第一次连接电源板 跟功放板 要把大电容的电放完!不要用手摸功放板输入端去看有没有信号!输出不能短路!不然易挂!
7294推荐工作电压
VS = ± 35V, RL = 8Ω
VS = ± 31V, RL = 6Ω
VS = ± 27V, RL =4Ω
3886推荐工作电压
VS = ± 35V, RL = 8Ω
VS = ± 28V, RL =4Ω
1875推荐电压
VS = ± 25V
1876推荐电压
VS = ± 22V, RL = 8Ω
VS = ± 20V, RL = 4Ω
4766推荐电压
VS = ± 30V, RL = 8Ω
VS = ± 26V, RL = 6Ω
