2.The input coupling capacitor adopts a German imported capacitor of 50V/3.3UF, and the electrolytic
capacitor signal main circuit adopts an imported brand.
3.The resistance adopts a five ring metal resistor, and the main circuit adopts a five ring metal film
resistor with an accuracy of ± 1%, ensuring a good signal-to-noise ratio of the entire machine.
4.The PCB is made of 1.6mm thick double-sided sheet metal, with a thickness of 2.0A copper and a
full process of tin spraying, ensuring good performance in passing large and small currents.
The wiring layout of the entire circuit board is quite rigorous and reasonable, and the overall PCB wiring
adopts a single point grounding method. This power amplifier board works stably and reliably, with high
output power; The voice is beautiful and round, with an open field. Strong three-dimensional sense, stable
and solid low-frequency, excellent signal-to-noise ratio, and wide dynamic range; Clear details, excellent
transient response, and able to handle various types of music, performing well in home playback environments.
