Active #speakers refer to a type of #speakers with self-equipped power amplifiers inside the #speakers. These power amplifiers are specially used to drive the #speakers in the #speakers. Due to the special matching design, these power amplifiers can be better used to drive the #speakers in the #speakers, so that users do not need to consider how much power the power amplifier is. And whether the impedance matches and other issues. In addition, because the #speaker is also equipped with an electronic frequency divider that divides the frequency in front of the amplifier and each amplifier is only responsible for amplifying the audio signal of a certain frequency, the efficiency of the amplifier can often be made higher, and the distortion is relatively good smaller.
The #speaker is powered by 220V power supply, the power supply is guaranteed, the power is larger and more stable, the high-power switch, the versatility is stronger, and the plug and play.Independent operation panel, equipped with an interface that supports SD card/U disk, plug and play, volume adjustment, song switching, and mode switching functions.
