The main circuit of the electrolytic capacitor signal adopts ELNA and NXB famous brands, the main filter capacitor adopts Japan Chemical with a capacity of 4700UF/80V*4, and adopts a double rectifier 25*2 (50A) rectifier flat bridge to ensure strong and continuous power support.
The five-ring metal resistor is used for the resistor, and the five-ring metal film resistor with an accuracy of ±1% is used for the main circuit, which ensures a good signal-to-noise ratio of the whole machine.
The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. Top-notch PCB quality. 20A high current shielding inductor is used to ensure the sound is clear and powerful.
The wiring layout of the entire circuit board is quite rigorous and reasonable, and the overall PCB wiring adopts a one-point grounding method. The power amplifier board works stably and reliably, with large output power; the sound is beautiful and round, and the sound field is wide. Strong stereo sense, stable and powerful low frequency, excellent signal-to-noise ratio, wide dynamic range.
