Review on 🔊 AIYIMA DC12V-24V 2.1 Channel TPA3116 Subwoofer Amplifier Board High Power Bluetooth Audio Amplifier Board 50W+50W+100W (Bluetooth Amp) by Aaron Guy

I bought this board with the intention of using it in a semi-portable bluetooth stereo but after receiving and testing it I will now use it to to replace my desktop computer TPA3116 Amplifier 2.1 because the quality of the sound is so good. The components and overall construction are great, as is all the soldering points, which isn't always the case as I've had to re-solder several other amplifier boards/modules I've bought for projects. There is a barrel-shaped plug and a screw terminal for power supply. The amp runs on 12 to 24 volts, but I would recommend 24 volts for the best sound and results. I would also recommend using a good quality power supply as this is almost always the cause of the audio quality issues people typically try to plug into an amp. It has a 3.5mm input and a 3-pin audio input for connecting another input, e.g. B. an RCA connection. It also has a full set of USB pins (5V, G, D1, D2) that you can connect a USB cable or plug to, although I haven't checked what capabilities it has, but I'm assuming assumes it is a source input. Bluetooth version 4.0 is clean and I connected to it with no problems, but I didn't do many range tests. I tested the sound with a pair of Micca MB42X speakers and an 8" Tang Band subwoofer and was very pleased. Materials and circuit layout and this is by far one of the best I've heard and as I said it replaces my desktop TPA3116 once I've finished printing its case.It came well packaged with some standoffs and mounting screws and some plastic knobs on the potentiometers.I can't say enough good things about the seller either and I highly recommend buying it.They answer everyone my questions are quick and very knowledgeable, and if they do not know the answer immediately they will find it and contact me I recommend this TPA3116 2.1 amp to any of these modules, you will not be disappointed.
