This small, high-performance Class D amplifier module uses an Infineon MERUS™ MA12070 amplifier chip allowing it to develop a power of 2*35W under 4Ω (1% THD+N) while offering high efficiency and precise and detailed sound reproduction. The module provides a USB-A input to connect a storage device such as a USB key or an external hard drive, but above all has a Bluetooth 5.0 receiver as well as a 3.5mm jack input. This allows you to stream and control your music remotely from a smartphone or tablet for example. On the output side, the card is equipped with screw terminals for the speakers. A volume knob is also present for easy and convenient sound level adjustment.
