Using imported TPA3221 digital chip. The main filter capacitor adopts imported 1800UF
The resistors are high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine.
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.
The input and output use gold-plated RCA lotus seat, durable and beautiful!
The board wiring is reasonable, beautiful, and low noise. Bluetooth uses Qualcomm QCC3034 module to support sbc, aac, aptx, aptx-HD. Bluetooth DAC uses PCM5102 to decode independently
Main features of TPA3221:
