400 Watt LC Filter Module

Supplementary explanation: High and low speakers: connect according to the method in the left figure. Full-range single speaker: connect to the bass position, and then connect a section of wire from the treble "+" to the bass "+".

Everyone knows that the crossover is installed in the speaker to achieve sound division and change the effect. The old crossover is rigid. If the user installs it and it is not suitable, it will not be changed. Sometimes the treble is too strong and the bass surface is poor, or the bass is too thick and the overall performance is not clear, etc., which is difficult for beginners to solve; if the crossover is changed, it may not be suitable, and the cost is high. This crossover is a multi-purpose, adjustable, welding-free, very convenient to use and effective. Listeners can realize debugging and self-control according to their own preferences. It has a wide range of uses. It can be used for treble + bass two-way speakers, 2.1 mid-high small satellite boxes and car full-range speakers, and can also be used for treble or bass alone. The impedance of the speaker can be used from 4 to 16 ohms. As long as the power of the speaker is below 400W, there is no problem.

Jumpers A, B are used to control the bass range audio effect. A for the lower limit and B for the upper limit of the bass audio range. For some speakers, when the Bass is raised too much, the speaker will show distortion. When this happens: We remove the jumper cap of jumper A to limit the super low bass to reduce distortion. When we remove the cap of the jumper B, the bass increases while the cap of the jumper B is active, the bass decreases. Jumpers C and D are used to control the treble range. When the hoods of both jumpers C and D are active, the treble sound is louder. When only cap C is active, the treble sound is lower. When only cap D is active, lower further. When both caps of C and D are removed, there is no high pitched sound. (In general, with the four jumpers, sooner or later you may find your best sound effect. However, all effects still depend on your actual test.)

First connect according to our diagram above (Treble, Bass, Input), connect to the speaker, seal the air gap, we can start hearing the music by optimizing.

We normally use jumper A and leave B inactive. For jumpers C and D: we need to hear the real effect of the treble. A general formula is: A + D = better bass; A + C = cancel ups and downs; A + CD = Clear Treble and Bass (the overall effect inclined towards Treble); AB + CD = most average frequency. When the bass effect is unnecessarily high, we can remove the cap A. Optimize until you think the sound is the best, then fix the board with your speaker.
