Description:
1. Two original TPA3116D2 digital power amplifier chips are sampled, one of which is used as left and right channel power amplifier, and the other is bridged with NE5532 to drive subwoofer.
2. It has the characteristics of small size, high efficiency, high power, small heat generation, etc. (the upgraded version adopts red metal coil, with better heat dissipation).
3. NE5532 is a high performance low noise dual operational amplifier (dual operational amplifier) integrated circuit. It is similar to many standard operational amplifiers, but it has better noise performance, excellent output driving ability, quite high small signal bandwidth, large power supply voltage range and so on.
4. Therefore, it is suitable for high quality and professional audio equipment, instruments, control circuits and telephone channel amplifiers. Warm voice and high fidelity when used as audio amplification.

Warm Tips:
1. Generally, the power supply and power amplifier should be kept at a certain distance to avoid electromagnetic interference.
2. It is better to use high quality power supply, which will be stable. If power supply such as transformer is used, it is better to cover the voltage changer with metal cover to prevent electromagnetic interference

Note:
Please allow 1-3mm differs due to manual measurement.
Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
