Petit ampli très intéressant, qui trouve vraiment tout son sens en y ajoutant le câble et la liaison USB pour avoir accès au DSP. La qualité sonore restituée est vraiment agréable, le son est clair, et le DSP intégré permet de "tricher" un peu sur l EQ pour corriger certains trous de réponse en fréquence éventuellement, et forcer un peu la descente en fréquence de l'enceinte en ajoutant qqs DB à la f-3 par exemple. La fonction bass boost pour ma part m a servi à compenser le baffle step de manière numérique sans devoir complexifier mon crossover passif. On peut également jouer sur les effets de profondeur stéréo, utilisés dans mon cas pour redonner de l'espace à l'écoute dans une box bluetooth ( et ça marche très très bien, en prenant le temps d écouter et corriger de manière dichotomique ) . Le point "négatif" : je doute TRÈS fortement que les puissances annoncées soient celles restituées, c'est plus que certain....Cependant le volume (pilotes en 8 ohms dans mon cas de figure ) reste bien plus que largement suffisant pour une écoute domestique dans un salon de 20m2.

Class D Amplifier Module TPA3221 Bluetooth aptX TWS 2x100W
The TinySine TSA7510B is a Class D amplifier module capable of delivering 2x100W with a high efficiency of 90%. It can therefore be combined with passive speakers in 2, 4 or 8Ω. It also includes a Bluetooth AudioB Plus module, giving it a significant user comfort since you can broadcast your audio files directly from your smartphone or tablet. This Bluetooth module includes an SMA connector, allowing you to connect a Bluetooth antenna (sold separately) to it in order to improve transmission quality and maximum distance. In addition, the Bluetooth chip supports the aptX and aptX Low Latency protocols to improve transmission rate and stability in order to improve the quality of sound reproduction.
The TSA7510B also supports TWS mode. It is possible to combine two TSA7510B modules together to stream audio files to them at the same time.
The module is also versatile as it can be connected to other TinySine add-on modules (sold separately) such as the TSA1000, TSA1010 and TSA1020 volume controllers. An additional line output also allows you to connect a subwoofer to it.
Connection diagram
The TSA7510B automatically detects the audio input, with Bluetooth having the highest priority. When Bluetooth is disconnected or not used, the amplifier will use the AUX / Line outputs.
