This Class D stereo amplifier module embeds a TPA3116 chip, capable of delivering 2x50W power under 4Ω or 2x30W under 8Ω with a high efficiency, higher than 92%, while offering a clear and detailed reproduction. It also integrates its own volume control allowing to easily adjust the volume level. The amplification chip is topped by a heat sink to efficiently evacuate the heat released. An additional supplied fan can also be connected to the module for further dissipation. The module also benefits from a complete protection circuit against overvoltage, undervoltage, overcurrent, overtemperature and short-circuit.

On the connectivity side, the input is made in Jack 3.5mm or via a connector XH2.54mm 3 pins. A Bluetooth 5.0 reception chip allows it to broadcast its music remotely from a smartphone or a tablet for example. The Bluetooth antenna can be remote for an easy integration in the box thanks to a U.FL connector (external antenna sold separately). The output to speakers is done using screw terminals.
