Feature:
1. Digital amplifier board adopts special inductance for audio to keep clear and powerful sound.
2. The resistor uses high‑accurancy chip resistors enables to keep a good signal‑to‑noise ratio.
3. Adopts imported TPA3255 chip, AMP board's quality is guaranteed, you can use it with confidence.
4. Supports class D working method, digital amplifier board installation is simple.
5. Practical adoptability keeps its high performance for a long time, which makes amplifier board with wide application.
Specification:
