Details: 

1. Using Original TPA3116

2. The electrolytic capacitor signal main circuit designer from Taiwan, Japan Chemical main filter capacitor capacitance electrolytic capacitors dedicated 4 × 3300UF, ensure strong support for a steady stream of power.

3. Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% chip resistors, ensure the machine a good signal to noise ratio.

4.PCB using 1.6mm thick double-sided sheet, 2.0 oz copper thickness, HASL whole process to ensure the size of the current through the good performance. PCB-class quality.

5. fully enclosed dust-proof potentiometer, the performance is more stable, more durable than ordinary potentiometer!

6. Using red gray loop inductance high-current audio dedicated to ensure the sound crisp and powerful.

7. The switching signal components using good quality Hongfa relays

8. Connect a Bluetooth connection and the way ordinary devices like! The search appliance (YJHIF) - point (YJHIFI) connected devices - to play music

9. Enter the Bluetooth mode and analog input, two ways at the same time to enter the Bluetooth input priority, need to simulate please turn off Bluetooth phone can switch input
