Description: Introduction to DC power filter circuit: The circuit consists of three parts: the first part is a primary LC filter circuit, the second part is a common mode EMI filter, and the third part is a secondary LC filter circuit. LC filter, commonly known as passive filter, is a traditional DC power harmonic compensation device composed of inductance and capacitance, which can filter out harmonics in the power supply once or multiple times and purify the DC power supply Common mode filtering can address the problem of rapid ient group pulse interference with a repetition frequency of several thousand hertz in certain user sites, and can play a suppressive role. The PCB specification is FR4 42X77X1.6MM, with the shortest design for high current circuits and short paths, which can withstand higher currents and minimize external interference. The equipped inductors come in specifications: 20A. Features: 1. Small and exquisite 2. Reliable Performance 3. Low consumption 4. Wide range of use 5. Shortest design of high current mission lines. Specifications: Input: DC shall not exceed 50V (electrolytic capacitor can be replaced for lifting at higher voltage) Output: DC Current: 20A Circuit board: double-sided FR4 fiberglass board Electrolytic capacitor: 50V 470UF consumption 2 PCS Thin film capacitor: 100NF 2PCS 470 PF 1PCS Magnetic ring inductance: dosage 2PCS, (iron silicon aluminum is selected for 20A high current), Common mode inductance; Usage: 1 PCS, (flat copper with high current of 20A) Socket: 7.62 socket, 2PIN, 3PIN, 1 PCS each This module is suitable for eliminating DC power sources with electromagnetic interference and can be applied to DC circuits with strong electromagnetic interference in automobiles, motorcycles, and other industries. note: Different batches, the appearance/color of the electronic component on the product may be different,

Commonly used in treble + bass two-way stage speakers, the treble has two tuning methods: treble/super treble, and the bass has two tuning methods: mid-bass/bass. It is suitable for high-power speakers of around 800W. This model can control and change the sound quality by itself, and debug the effect that the user likes. Ancient crossovers are rigid and cannot be changed if the user installs them inappropriately. Sometimes the treble is too strong and the bass performance is poor, or the bass is too thick and the overall performance is unclear. Various effects are applied in various venues. Sometimes a set of stage speakers is adjusted to meet the needs of speeches (AV). The clarity of human voices is very good, but the bass is not so powerful when listening to KTV or DJ disco; On the contrary, when it is adjusted to KTV or DJ with strong bass, it is very exciting to listen to the bass d , but it is not so natural, bright and sweet when listening to human voices. The direct-tuning version of the crossover is installed outside the cabinet and can be combined into 4 effects. The user can change it at any time, covering multiple crossover points, and the changing effect is more subtle. The in-box debugging version can only be debugged to achieve the correct effect, while the out-of-box direct-tuning version is different. It can be combined with various changes to suit your wishes. Can be debugged and can change the effect: The crossover wiring panel is equipped with two switches to control different circuit combinations and change the sound quality effect. The sound of the speaker connected to the bass switch is limited to below 700~800Hz (8Hz/0Hz). Treble sound is limited to above 4k~7kHz (3dB/0dB). With socket, no soldering is required, the wires can be twisted with a screwdriver, and the installation is convenient without soldering iron. Components used: 1. Special capacitor for audio; 2. The inductor is wound with high-tempe
