According to the application data of the chip, the author can design the mid-range signal to be adjusted by RP1, which can properly adjust the vocal dialogue, the power supply reverse connection protection and the three-terminal regulator in the circuit, which is convenient to install into the power amplifier and video disc. Machine, active speaker, multimedia computer, car audio, etc., because this fever board has a three-terminal regulator, DC power can be taken from the DC power supply (+10V to 18V) in the machine, I use the circuit and related The circuit assembled a set of value-for-money home theater combinations and audition, the configuration is as follows: sound source (VCD) → QS7779 → I designed the integrated LM1036N (with volume, tone, balance, equal loudness) + LM4562 + power amplifier circuit (TDA7293X2 Double 140W current feedback DC servo integrated bile flavor fever finished board, no noise after connecting the two. A Dolby disc "Broken Arrow Action" put into the SAST Super VCD, with the development of the plot, the three-dimensional sense of space And the sense of envelop is very strong, with the appearance of the plane, hey! Very realistic feeling of presence appeared: I heard the plane flew from his right front to the left rear, feeling the plane Flying over the top of the sound, immersive feeling! And the QS7779 is connected to the through state, only to hear the sound of the aircraft is the right speaker to the left speaker, the sound is very monotonous. So the QS7779 is connected to the three-dimensional virtual surround sound The processing state continues to audition... The entire viewing process is very realistic, the sound image is positioned accurately, and it has an immersive experience.
