    Bluetooth 5.0 TPA3116D2 2.1 digital power amplifier board 50W*2+100W/ subwoofer
    Description
    Description:
    This board is specially designed for home and car 2.1 systems. With passive 2.1 speakers, it can get shocking and realistic live effects, and it can also achieve high-fidelity 2.0 HIFI music playback.
    Because the board does not have a shell, good power and signal lines are essential. It is best to wear the knob or connect to the signal ground, otherwise the direct touch of the board or potentiometer will induce interference sound.
    Do not use a wooden case for the chassis. The wooden case does not dissipate heat well, has no mute shielding effect, and the Bluetooth receiving distance is more than 7 meters. If you can’t reach it, the antenna is not connected.
    Please check the power of the power supply in your hand. If you only have a 12V 2A power supply with a board, the evaluation that can be obtained is definitely insufficient. 12X2A=24W. The power supply is not strong enough, and the power amplifier cannot output enough energy. Remember, it is recommended to get enough power and the power supply should be 19V 4.7A or above
    A series of high-end components such as 6 oxygen-free copper output inductors, gold-plated input base, etc., the sound quality improvement is proportional to completion (4700UX1 with Bluetooth board)
