product details:

1. Using original TPA3116


2. The main circuit of the electrolytic capacitor signal adopts Taiwan, and the main filter capacitor adopts the special electrolytic capacitor capacity of 4×3300UF for Japanese chemical industry to ensure strong and continuous power support.

 

3. Five-ring metal resistor is used for the resistance, and the main circuit adopts a chip resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine.

 

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

 

5. The fully enclosed dust-proof potentiometer is more stable in performance and more durable than ordinary potentiometers!

 

6. The red-grey ring high-current audio special inductor is used to ensure the sound is clear and powerful.

 

7. The switching signal element adopts a high-quality Hongfa relay

 

8. The way to connect to Bluetooth is the same as that of ordinary devices! Search device (YJHIF)-click (YJHIFI) to connect the device-play music

 

9. There are bluetooth and analog input as input methods. When the two methods are input at the same time, the bluetooth input has priority. When analog input is required, please turn off the Bluetooth function of the mobile phone to switch.
