DESCRIPTION
Features:
Using original genuine LM3886 chip;
The front input capacitor and the inter-stage coupling capacitor use Siemens top-level capacitor 2.2UF, the electrolytic capacitor signal main circuit adopts Taiwan famous brand, the main filter capacitor adopts capacity 4×4700UF, and adopts 10A and above rectifier flat bridge to ensure a strong source of continuous Power support.
The resistance adopts five-ring metal resistance, and the main loop adopts five-ring metal film resistance with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine.
PCB adopts a 1.6mm thick double-sided board, 2.0 ounces copper thickness, and a full tin-spraying process to ensure the good passing performance of large and small currents. First-class PCB quality;
The machine adopts all-aluminum chassis, and the surface of the chassis is processed by brushing the oxidation coloring process;
The wiring layout of the entire circuit board is quite rigorous and reasonable, and the overall PCB wiring adopts a one-point grounding;
The power amplifier board is stable and reliable, and the output power is large; the sound is beautiful and round, and the sound field is wide.
Strong three-dimensional sense, low frequency is stable and powerful, the signal-to-noise ratio is quite excellent, the dynamic range is wide; the details are clear, the transient response is excellent, and all kinds of music can be played easily, and it has a very good performance in the family's playback environment.
The wiring of this board is very simple. As long as there are few parts, it can be assembled into a beautiful stereo HIFI combined power amplifier, which is very suitable for audio enthusiasts. You can also replace the more suitable and better parts according to your understanding of the circuit, and enjoy the fun of the DIY process. (Absolutely worth a try, the effect is very good);
