This small, efficient, versatile and affordable Aiyima A03 Class D amplifier provides 2x50W of power at 4Ω thanks to its TPA3116D2 amplifier chip, more than enough to soundtrack a small or medium-sized room. This one also has a subwoofer output with a power of 100W for an audio integration in 2.1 with a nice base in the bass.

The front panel of the A03 features a series of knobs that allow you to adjust the overall volume as well as the bass and treble levels of the stereo speakers and the crossover frequency and volume of the subwoofer. The amplifier thus demonstrates its versatility by adapting to your listening and your audio system.

On the connectivity side, there is a stereo RCA input but above all a Bluetooth 5.0 receiver using a QCC3034 chip. It is thus possible to diffuse and control very easily its music in wireless from a smartphone or a tablet for example. The output is done in a classic way on HP terminals.
