XH-M590 two-channel digital power amplifier board, input voltage is DC12-24V, onboard RCA and 3P terminal two audio input methods, more convenient to use The power amplifier board is also equipped with a 50K volume adjustment potentiometer, which can adjust the volume at any time; dual-channel audio output, power is 2*100W. This power amplifier also has speaker protection, and there is no current impact sound when switching on and off. Volume adjustment potentiometer XH-M590 comes with a volume adjustment potentiometer, which is convenient and practical; turn clockwise to turn on the volume and increase the volume, and turn it counterclockwise to decrease the volume to turn off. Two audio input methods XH-M590 uses two input methods, RCA and 3P audio terminal, which is more convenient to use; (but the two input methods cannot be used at the same time) The heat emitted by the high-efficiency array radiator chip produces the "heat island effect" from the center through the staggered channels. The array-type heat dissipation structure helps air convection and clearing, and the heat dissipation channel is more smooth and high heat dissipation efficiency.
