gned to enhance the stereo sound system, so that a variety of sources can exhibit strong spot sense. It uses bipolar integrated manufacturing process, low noise, total harmonic distortion, large adjustment range, dual power supply, electrical parameters in Table 5-9 are shown o 1071 for the 32-pin dual in-line package, which is incorporated pin function Description Table 5-100 application circuit shown in Figure 5-19 O XR1071 addition to the audio signal phase compensation, amplitude compensation (harmonic compensation), to enhance the bass contour, but also has a bypass function, to work in a bypass mode noise is very low. BBE bypass function with two analog switches to complete (each sound track with one), externally controlled by a switch to sing debate. After the pin 1 of 6 external switch is closed, IC inside there will be a pull-down current.
