Typically used in two-way stage speakers with treble and bass. The treble has two adjustment methods: treble/super treble, and the bass has two adjustment methods: mid-bass/bass. It is suitable for high-power speakers of approximately 800W. This model allows you to control and modify the sound quality yourself, tuning the effect to your preference. Unlike old crossover filters that are fixed and unchangeable, this allows for user adjustments. If the treble is too strong and bass performance is poor, or if the bass is too thick and the overall performance is unclear, this crossover can be adjusted. Different effects are applied in various venues. Sometimes, a set of stage speakers is adjusted to meet the needs of speech (AV), providing excellent clarity for human voices, but lacking powerful bass for KTV or DJ disco. Conversely, when adjusted for strong bass in KTV or DJ settings, it's exciting for bass drums but not as natural, bright, and sweet for vocals. The direct-setting version of the crossover is installed outside the cabinet and can be combined into 4 effects. Users can change it at any time, covering multiple crossover points with more varied effects. The built-in tuning version can only be debugged to achieve the desired effect, whereas the output direct-setting version is different and can be combined with modifications to suit your preferences. Adjustable and Effect-Changing: The crossover connection panel is equipped with two switches to control different circuit combinations and alter the sound quality effect. The sound from the speaker connected to the bass switch is limited to 700~800Hz (8Hz/0Hz). The treble sound is limited to above 4k~7kHz (3dB/0dB). It features sockets, requiring no soldering; wires can be twisted with a screwdriver, making installation convenient without a soldering iron. Components Used: 1. Audio-specific capacitor; 2. Coil wound with high-temperature resistant enameled wire and using a high-temperature resistant blue skeleton; 3. Special circuit board base and solderless terminal blocks for high-performance stage speakers, eliminating the need for soldering; 4. High-current switch on the panel easily adjusts 4 crossover points, ranging from 6dB to 18dB; 5. Sound quality can be adjusted to 4 sound quality effects via the switch. The design is reasonable, the appearance is exquisite, and the sound quality is pleasant.
