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.
