DAMGOO Audio Amplifier Board with Bluetooth 5.0, 10W 15W 20W 2.0 Dual Channel Stereo Wireless Mini Amp Module with Protective Shell

¡Este pequeño amplificador funciona muy bien! Yo lo usé para conectar un par de bocinas exteriores y lo alimento con música vía Bluetooth desde el móvil. Estoy usando un eliminador de baterías de 12 V y 1.2 A y funciona muy bien. Es realmente muy pequeño (como la mitad del tamaño de una tarjeta de crédito), por lo que se puede usar en cualquier espacio. La instalación no tiene problema alguno y en menos de 5 minutos queda listo para funcionar...Recomiendo hacerse de un eliminador de baterías que tenga distintos tamaños de salidas para no errar al seleccionar el necesario para la entrada del amplificador.

I don't often buy things that don't yet have a review, but at this price I figured I go for it. This thing is awesome. It is tiny, less than half the size of a credit card. And it is loud! Also, the Bluetooth antenna is great! I can walk around my house with my phone and I haven't gotten it to cut out at all. I have a Bluetooth speaker that cuts out if I just go to the other room.I ran it into 8ohm speakers with 24v\1a and 12v\5a power supplies I have on hand and both work great. I did notice that the board ran quite warm with the 24v power supply. The instructions do say that if you run 24v to use a heat sink. The board itself is very neat and the black PCB is a nice touch. The included acrylic and standoffs are a nice touch.I only have two criticisms, which are minor especially considering the price:1) the included DC plug is wired incorrectly. The red wire is negative and the black is positive. The board itself is marked correctly. I could not initially get it to work due to this. I sent an email to the address on the documentation and they responded very quickly and let me know if the problem. I swapped the wires and it worked perfectly. The support person said that they are working to update the included documentation.2) The beeps that let you know it turned on, volume maxed, Bluetooth connected, and Bluetooth disconnected are fairly loud. The nice thing, though is that the volume maxed beep does not interrupt the audio stream.I've only had this thing for a few days. I will update it if anything drastically changes.

This little thing is foreal! and it pumps out some nice sound for such a little bluetooth amp. It's very small and delicate, but boy can this thing handle some power. I've had a 200w subwoofer and a 100w midrange woofer and this little Amp had no problem,never over heated or had any problems with it. Definitely worth the money because this unit and 2 20-30w speakers and your in business. I have 2 of these and to of a different kind and I love them. For the chump change they coast! It's way,way,way worth it to get some while there hot and the price is low.

tarjeta de audio y Bluetooth de buena calidad, la etapa de audio no es de buena calidad, se satura a bajo volumen, lindo juguete.

Works as described. Wish the volumne and pause play was bigger
