Description:Digital Amplifier Board: This is a DC single power supply 12-24V power supply, using TPA3116D2 high performance digital power amplifier chip as the core, 1 for parallel bridge bass channel power amplification output, 1 for left and right channel power amplification output

Can support 100W (bass channel) + 50W left channel + 50W (right channel) three channel output

Working Voltage Range: DC12-24V (current 3-4A, or 19-24v/4-5A, if the power requirement is higher than 20-24v/8-9A)

If you use AC (AC) er power supply, you must add rectification filter Convert to direct current (DC) power supply before it can be connected

Note that the direct current (DC) no load voltage should not exceed 25

5V

Easy to Use: The Digital power amplifier board is a finished board that has been soldered and tested

Connect the speaker box according to the diagram, connect the appropriate power supply, connect the audio device to play or correctly connect the audio input, and then it can be used

Features: Amplifier board supports audio reception, external audio input interface, with pre amplification, bass frequency division processing; bass volume, bass frequency, left and right channel volume, treble, function control switch/total volume, 5 adjustment potentiometers

Design: Wide working voltage, power saving design, efficiency up to 90%

It can be used with switching power supply with good performance, laptop switching power supply,etc
