ZK-TB21F TPA3116D2 BT 5.0 Subwoofer Amplifier Board 50WX2+100W 2.1 Channel Power Audio Stereo Amplifier for subwoofer

ZK-TB21 TPA3116D2 BT 5.0 Professional Amplifiers Board 50WX2+100W 2.1 Channel High Power Stereo Amplifier for subwoofer

Product selling point:
1. Exquisite appearance, beautiful arrangement of components
2. The product has its own protection mechanism: overvoltage, undervoltage, overheating, branch current detection, short circuit protection, etc.
3. The separate version of the potentiometer is easy to use and is not limited by the distance between the casings
4. High-quality power amplifier chip TPA3116D2 has AM interference suppression function
5. The gameplay is richer and more diverse: subwoofer expansion, adding a microphone front board

hint:
Only when the audio input is sufficient and the power supply voltage/current is sufficient, there will be sufficient output power! ! !
The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power! ! !
Please ensure that the power of the adapted power supply is greater than the actual working power of the power amplifier! ! !
