This power amplifier board uses the cool black design to improve all the shortcomings of the previous models, such as no-load heating, switching machine impact sound, bottom noise, low bass, etc., excellent re-editing this time will have a major breakthrough.
Compared with the above one, the two original TPA3116D2 digital power amplifier chips are still used. One of them is the left and right channel power amplifier with preamplifier, the other is high-definition and the other is combined with the NE5532 front bridge to drive the heavy bass. The overall layout is reasonable, the volume is small, the efficiency is high, the digital power is large, and so on. Features are a good choice for DIY!
