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.The vocal weapon, the all-cone tweeter has a high high-frequency upper limit and good extensibility, which can avoid hearing fatigue during a long time mixing process with natural and true sound effects.The newly designed 4-inch mid-woofer #speaker, high-intensity full cone diaphragm, the woofer sound is natural and harmonious, just matching the treble tone. The transient response is good, the low frequency is strong and powerful, and the dive is good.No bottom noise, no noise. There is no current impact sound when starting up, high fidelity. The treble is delicate, soft, transparent, non-obviously harsh, and the bass is full, powerful, and freely retractable.It is suitable for classrooms, meeting rooms, restaurants, living rooms, study supermarkets, factories and other business places as background speakers or broadcast speakers.No matter what environment you use, the side-mounted control knob and multi-function remote control will greatly facilitate your use. When you are used to the convenient and convenient operation, you will only be even more admired!
