1. Using original imported TPA3250

2. The main circuit of the electrolytic capacitor signal adopts a chip electrolytic capacitor with a capacity of 2×470UF, which ensures a strong and continuous power support.

3. The resistors use high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine.

4. 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 and PCB quality.

5. Fully shielded high-current inductors are used to ensure clear and powerful sound.
