Product description
The use of high-quality parts not only guarantees safety and quality, and has a long service life, but more importantly, it is a strong guarantee that the actual performance can reach the design goal. Using TPA3221
The main filter electrolytic capacitor adopts the imported famous brand Erkang with a capacity of 2200UF/35V*4, which ensures strong and continuous power support.
The resistors are high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine.
The use of special magnetic ring inductors for audio ensures that the sound is clear and powerful.
PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tinning process to ensure good passing performance of large and small currents. First-class PCB quality.
Working voltage: DC19V-30V switching power supply (DC) DC24V is recommended
