Description
Using the original TPA3116
Electrolytic capacitor signal main circuit using Taiwan famous brand, to ensure a strong stream of dynamic support.
Resistance selection of five-ring metal resistance, the main circuit with precision ± 5% of the chip resistors to ensure a good signal to noise ratio.
PCB with 1.6mm thick double-sided sheet, 2.0 oz thick copper, tin spray the whole process to ensure that the size of the current through the performance of good. First-class PCB quality.
Using full-shielded high current dual inductors to ensure that the sound crisp and powerful.
This board adopts the latest start-up delay circuit, effectively eliminate the boot shock
