Class D Stereo Amplifier TPA3251 2x140W 4 Ohm

Class D Stereo Amplifier

This affordable Class D amplifier is based on a TPA3251D2 amplification chip, delivering 2x140W at 4Ω with high efficiency. It will therefore have no difficulty driving most speaker models. In addition, it benefits from PurePath Ultra HD technology, maintaining a very low distortion level across the entire frequency range while offering excellent sound precision.

The amplifier features a solid build quality, using proven audio-grade components. The power stage notably uses two 50V 1000µF Nichicon capacitors for electrical signal filtering.

In terms of connectivity, this model remains simple, with a stereo RCA input, a 3.5mm AUX output, and of course speaker binding posts. This notably allows for a 2.1 channel system setup with an active subwoofer.

bon simple efficace.
ne fonctionne pas en 15 volt. En 20 volt si. Très bon grave. Tweaks possibles: virer les borniers haut-parleurs pour sortir des câbles depuis l’intérieur de l'appareil et également souder directement des câbles rca DIY en cuivre émaillé de petite section (déjà essayé sur smsl sa-50 avec gain qualitatif parfaitement audible).
Notez que sur batterie Li-on 20 volt 2A le gain par rapport à une alimentation 28 volts 5 A 'de laboratoire' n'est pas évident à discerner sur enceintes haut-rendement transparent, ... peut-être dans le grave mais pas assez de temps d"écoute pour l'instant. En tout cas l'ampli ne laisse pas passer le bruit résiduel de l'alimentation secteur, le medium aigu reste très bon. Merci Bonnes écoutes à tous.
