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!
