1. Using original TPA3116

2.DAC uses Texas Instruments PCM5100

3. Bluetooth uses Qualcomm QCC3003 Bluetooth 5.0 chip

4. The power filter capacitor adopts imported 470UF/25V and electrolytic capacitors

5. The main circuit of electrolytic capacitor signal adopts Taiwan, and the main filter capacitor adopts imported Sanying electrolytic capacitor to ensure strong and continuous power support.

6. The five-ring metal resistor is used for the resistor, and the five-ring metal film resistor with an accuracy of ±1% is used for the main circuit, which ensures a good signal-to-noise ratio of the whole machine.

7. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents and PCB quality.

8. The red and gray ring special power amplifier is used to ensure the sound is crisp and powerful.
