MakerHawk Mini Bluetooth Amplifier Board 2.0 2X50W 5V-24V Audio Power Module for Store Home Theater Speakers

Esta compra me super agrado, nunca imagine que este super pequeño amplificador alimentaria mis bocinas Micca y las llevaria a un muy alto volumen. Es fantastica, solo asegura alimentar adecuadamente y el equipo te sorprendera.

Pretty easy to put together with the provided screwdriver, even though there are no instructions. I had to look at the pictures in the Amazon listing to see how and where to put the heat sink. There a little insulating sheet that goes under the pc board, with holes where there are wires on the bottom of the pc board. The underside of the power and speaker connectors extend into and thought these openings. The screws that hold the amp together raise it just enough so that they don't touch a flat surface, but if it were set on a coin or key, for example, you might get some sparks.The sound is great. I'm running it with the 12 v supply from the 20 watt x2 amp I had, that became scratchy or noisy after 10 years or so, and volume is plenty for me, with a pair of little Yamaha NS10 speakers. It also looks nice.I'm using stranded 16 AWG wire to connect the speakers, and it's a little hard to get into the screw connectors. You have to get all the strands straight. Also they are really close together, so watch out for stray strands that could cause a short.The amp is so tiny and light I had to be careful how the speaker and power wires are arranged so they don't pull it around.

Currently using with a 12V, 40A, 100% duty cycle power supply to drive some 6 ohm bookshelf speakers.If the specs are to be believed, this little board is supposed to be able to pump out 12W per channel at 12V with 8 ohm speakers so, my best estimate is that it should be able to provide about 15W per channel in my configuration.To be honest, I'm not sure I'm getting that kind of volume but, other than that, this thing is great.Sound fidelity is amazing for what this is. The BT connection tone is pleasant and not overly loud. Connectivity is good and I absolutely love the analog style volume control with off switch. The noise to signal ratio is really good (no hissing or popping).

So far, I like this little amp. It came packaged well: small box with a disassembled unit that you put together. I'm a tinkerer, so that's perfect! It was easy to assemble. Took less than 5 minutes. It has a 3.5mm stereo jack or blue tooth for pairing to a phone. I tried both and they worked well. Sound quality is good, albeit I don't have my speakers mounted in a box yet, so I'm hoping for a marked improvement. All in all, I'm happy. If you're expecting high end perfect performance, you probably want to go with something more costly. If you're building a simple stereo project for the fun of it, try this out. It's cheap, small, and funCON: didn't come with a power supply. I received some advice from others and ended up powering it up with an old 12v 3.5A adapter from my old Netgear router. It worked! I'll get a better 12V or 24V 10A supply later.

Buen rendimiento y cumple con las espectativas.
