Description:
The power amplifier board adopts one piece of TI's latest digital chip TPA3116D2 to do the power amplification of the left and right channels, and the efficiency is up to 90%. It has the characteristics of small size, high efficiency, high power and low heat generation. The pre-stage circuit uses NJM4580 for small signal processing. This freight has extremely low distortion, very low noise and high bandwidth. The treble is clear and the bass is powerful. The material is not used for cost. It is filtered by black diamond high frequency and low resistance. Taiwan-made sealed high-quality potentiometer, original chip, new SMD chip device, green slotted radiator. The board is beautiful and stable, and the work is stable and reliable.

Note:
1. The power supply limit voltage is 24V, please do not exceed! Otherwise, the capacitor is easy to burst, and the peak value of the voltage used for AC rectification should not exceed 25V. Do not supply power above this voltage. Reverse the positive and negative poles.
2. The power supply is recommended to supply 22V/5A or better. The lower the voltage, the smaller the power. Many use 12V power supply, saying that the power is insufficient. In fact, the power is only about 2*15W.
3. Speaker recommended 40-80W speaker
4. Do not short the audio output to each other or to the ground
5. Please check carefully before powering on to ensure that the wiring is correct.
Package Included:
1 x TAP3116D2 Digital Amplifier Board
