NONDK Dual-Channel Digital Amplifier Board LM3886 500W+500W Dual Channel Audio Amplifier High-Power withVolume Adjustment

The PCB adopts 1.6mm thick double-sided board, 2.0 ounces copper thickness, and full tin spraying process to good passing performance of large and small currents. The resistor uses high- resistors, and the main circuit uses high- resistors with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine. Adopting the new IRS2092 IXTQ50N25T,The electrolytic capacitor adopts electrolytic to strong and continuous . The sound quality is soft, pleasant, and powerful. The main power supply voltage is +-80V, and the dynamics are very good.
