Features: The power is as high as 400W, which can stably matching power amplifier and the loudspeaker unit, ensuring not distortion and burning in dynamic scenes. Specially for two-frequency loudspeaker, the full frequency is accurately divided into low frequency and high frequency through the accurately calculated frequency division networking, and transmitted to the bass and treble units respectively. Effectively eliminate frequency and between units, significantly improve the layering, separation and resolution of sound, and achieve their respective duties. Equipped with multi-gear adjustable attenuator (such as 0/-2/-4dB gear), users can flexibly output according to the characteristics of high-pitched unit, listening environment and listening preference. At low loss and low phase distortion, and low error components are selected to minimize the dyeing.
