四、测试结果测试是在安装好机箱的顶板和底板的情况下进行的即是对整个放大器作了屏蔽之后进行的,如果不是这样感应的交流声等会对测试结果产生影响。1.均衡电路(1)RIAA偏差在输入端连接一个图4的逆RIAA电路,每个测试频率都在相同的输入电压的条件下测量输出电压。由于该逆
Fourth, the test results The test is installed in the case of the chassis and the bottom of the case is carried out after the shield was made of the entire amplifier, if it is not so sensitive to the exchange of sound will have an impact on the test results. 1. Equalization circuit (1) RIAA deviation Connect an inverse RIAA circuit of Fig. 4 to the input end, the output voltage is measured under the same input voltage for each test frequency. Due to the inverse
