The amplifier board delivers exceptionally clear sound right out of the box, with vocals that are very pleasant, smooth, and highly listenable. Its output is robust, providing excellent performance when paired with 2 to 4-inch speakers.
For power, it can be conveniently operated using a mobile phone charger or a computer USB port. A 5V 2A power supply with a TYPE-C interface is recommended for optimal performance.
Constructed with premium materials, the board features very low power consumption, minimal heat generation, and is designed for reliable long-term use.
