Note:

This board is a heavy bass preamplifier board.
It can't be connected directly to the horn/loudspeaker.
It must be connected to a pure final stage power amplifier board to make an active subwoofer.
The power of the pure final stage power amplifier board is selected according to the degree of shock of individual needs.
The higher the power of the stage amplifier, the more powerful the bass effect will be.
The so-called low-pass filter board filters out the high-pitched parts above the human voice, and retains the low-frequency part to zoom in to improve the bass playback strength, it does not hear human voices and high-frequency instrument sounds during playback.
Buyers must understand this knowledge to avoid using it and not knowing how to use it.
