Based on the chip's application data, I was able to design a mid-range signal adjustment using RP1, which allows for proper tuning of vocal dialogue, power supply reverse connection protection, and a three-terminal regulator in the circuit. This makes it easy to integrate into power amplifiers, video disc players, active speakers, multimedia computers, car audio systems, and more. Since this board includes a three-terminal regulator, I can draw DC power from the machine’s DC supply (+10V to +18V). I assembled a cost-effective home theater system using this circuit and related components. The configuration is as follows: sound source (VCD) → QS7779 → I designed an integrated LM1036N (with volume, tone, balance, and equal loudness) + LM4562 + power amplifier circuit (TDA7293X2, dual 140W, current feedback, DC servo, and integrated bile flavor). After connecting everything, there was no noise. I played a Dolby disc called "Broken Arrow Action" on the SAST Super VCD. As the plot developed, the spatial and immersive sense was very strong. A plane appeared on the screen, and I felt like it was flying from my right front to the left rear. It even seemed to fly over my head, creating a truly immersive experience. However, when the QS7779 was connected directly, the sound only moved from the right speaker to the left, sounding quite flat. So I continued testing with the QS7779 in the 3D virtual surround sound processing mode. The entire viewing experience was realistic, with accurate sound imaging and a strong sense of immersion.
