Stereo Class D TPA3251 2x140W 4 Ohm

Amplificateur Stéréo Class D TPA3251 2x140W 4 Ohm

This affordable Class D amplifier is based on a TOPA3251D2 amplifier chip, ensuring a power of 2x140W under 4Ω and this with high efficiency. It will therefore have no trouble accompanying most speaker models. Moreover, it takes advantage of the PurePath Ultra HD technology, allows to maintain a very low level of distortion on the whole frequency band, while offering a beautiful sound precision.

The amplifier benefits from a nice design quality, using proven audio components. The power supply stage uses two Nichicon 50V 1000µF capacitors to filter the electrical signal.

As far as connectivity is concerned, this model remains simple, with a stereo RCA input as well as a 3.5mm jack output and of course an output on speaker terminals.

Simple et efficace
Marche a la perfection, rapport prix / rendement au top.
Petit b mol pour le knob volume, manque de solidité a l'intégration mais rien de terrible.
