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 drum, 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. <br
