It is composed of three five-stage equalization circuits composed of transistors LM9014 . These three circuits are all selected from early imported radio recorder circuits. These circuits are all powered by a 7.5V single power supply. The five-stage balanced center frequencies are: 60 ratio, 150H, 500Hz, 1500Hz, and 10kHz. The control ranges are all ±10dB. All three circuits are equipped with equal loudness volume controls. circuit.     Among the three circuits, the circuit in Figure 4-32 uses a common amplifier and a band-pass filter composed of resistor-capacitor components connected in the feedback loop . These five band-pass filters have their respective resistor-capacitor components resonating with theirs. Center frequency. The adjustment potentiometer is set in the feedback loop of the amplifier. When the sliding point of the potentiometer moves upward, the amount of negative feedback of the amplifier circuit increases, while the input signal decreases, the gain of the amplifier decreases, and the center frequency corresponding to the corresponding adjustment point is attenuated. ; Otherwise, it will be promoted.
