50W+50W+100W BT5.0 Bluetooth Amplifier Board TPA3116 Power Amp Board Assembled for Subwoofer Speaker
Description:
TPA3116 amplifier board is powered by DC 12-24V. It uses the original TPA3116D2 high performance digital power amplifier chip (for TI) as the core. One chip is used as a parallel bridge to connect the bass channel power amplification output, while the other chip is used for the left and right channel power amplification output. It can support three-channel output, that is, 100W (bass channel) + 50W (left channel) + 50W (right channel).
It supports Bluetooth audio reception. It has sound source input interface, preamp and bass frequency division processing technology. There are 5 potentiometers: bass volume, bass frequency, left- and right-channel volume, treble, mater volume/switch.
It also adopts a wide operating voltage and power-saving design, with an efficiency of over 92%. It is suitable for switching power supply with good performance and notebook computer switching power supply. Users can also use idle power supplies such as fast chargers and car power supplies!
How to Use?
The board is a welded and tested before delivery. Your speaker is connected according to the picture. Connect a suitable power supply, connect a Bluetooth audio device to play music, or connect a sound source to input, and you can use it.
