nAdopt original TPA3255, OPA1632DR
nThe main filter electrolytic capacitor adopts capacity 470UF/100V*4 to ensure strong and continuous power support.
nThe resistor uses five-ring metal resistor, and the main circuit uses five-ring metal film resistor with ±1% accuracy, which ensures a good signal-to-noise ratio of the whole machine.
nThe use of audio special high-current inductor, to ensure that the sound is crisp and powerful.
n PCB using 1.6mm thick double-sided plate, 2.0 ounce copper thickness, spray tin full process, to ensure the size of the current good through performance of PCB quality.
