The TPA3116D2 amplifier board with digital chip level power after doing left and right channels of amplification, efficiency up to 90%, with a small, efficient and high-power, small heat characteristics. Foreline circuit using NJM4580 as a small signal processing, there is a very low distortion, low noise and high bandwidth, clear treble, bass strong, stable and reliable.
1. The power supply voltage limit is 24V, do not over! Rectified AC voltage peaks do not exceed 25V. Do not exceed this voltage, the positive and negative should not be reversed;
2. The power supply is recommended for 22V, 200W power supply is better than filtering;
3. The speaker recommended 40~80W horn;
4. Do not short-circuit the audio output to each other or shorted to ground;
5. Carefully check before power on, ensuring wiring is correct
