ขาย Csr8675 เครื่องขยายเสียง 100W + 100W พลังงานสูง Tda7498 2.0 บลูทูธ 5.0 เครื่องขยายเสียงดิจิตอล ราคาที่ดีที่สุด

Using TDA7498 CSR8675 5.0 Bluetooth chip. The power filter adopts an electrolytic with a capacity of 1800UF/35V. The coupling adopts German fever-grade WIMA electrodeless , which makes the sound more transparent. High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio. The 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. The special power discharge sense of the red and gray ring is adopted to ensure the sound is clear and powerful.
