2调音台电平的调节如果将上面举例的多级电压放大器比作一台调音台,调音台示意电路图见图2,则也可以将组成调音台中各部分对应成上述多级电压放大器中的五级电压放大单元,A1对应成单声道输入通道的输入放大级(包括Tr1,Tr2,IC1及其外围元器件组成的复合差分电压放大单元),也
2 mixer level adjustment If the multi-stage voltage amplifier above example is compared to a mixer, mixer schematic circuit shown in Figure 2, you can also make up the various parts of the console correspond to the above-mentioned multi-stage voltage amplifier In the five voltage amplifier unit, A1 corresponding to the input channel mono input amplifier stage (including Tr1, Tr2, IC1 and its peripheral components of the composite differential voltage amplification unit), also
