915 Generation D-50A Digital Tone Bluetooth Amplifier Board

1. Using TPA3116 and TL074 2. The main circuit of the electrolytic capacitor signal adopts a chip electrolytic capacitor with a capacity of 4x470UF, which ensures a strong and continuous .
3. The resistors use high-precision chip resistors to a good signal-to-noise of the whole machine.
4. The PCB adopts 1.6mm thick double-sided sheet, 2.0 copper thickness, and the whole process of spraying tin to good passing performance of and small currents. Top- PCB quality.
5. Using fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers! Fully shielded high-current inductors are used to clear and powerful sound.
