This small complete amplifier module is based on a TPA3116D2 amplifier chip. This allows it to deliver a power of 2x25W under 8Ω. In addition, the architecture of this chip allows it to ensure a low level of noise and distortion, while limiting jitter thanks to an integrated clock system and a PLL circuit. As the module operates in Class D, it has a high efficiency of more than 90%. A double NE5532 AOP takes care of the preamplification part and the tone control. The module includes both a volume knob and two other knobs to adjust the bass and treble levels, in order to adapt the playback to your system.

The module also includes a series of protection against overvoltages, undervoltages, high temperatures, short circuits and overloads. The TPA3116D2 chip is topped by a heat sink to evacuate the heat.

On the connector side, the module is simple and efficient, with screw terminals for power supply and speaker outputs, as well as a 3-pin XH 2.54mm connector to connect a source.
