    Ultra Low Frequency Active Line Array Speakers With 3 Channel Power Amplifier Module

    Single 18-Inch Line Array Sound System Active Ulf Speaker

    Competitive Advantage:

    YY series active frequency division mode, high power processing capability, good sound quality, light weight, easy to operate flight system, Beautiful Mesh Grid design

    Product features:

    YY series active subwoofers have built-in three-channel power amplifier module with high-performance digital signal processing system, two YY-5 matched with two full-frequency channel propulsion systems, the remaining channel pushes the ultra-low frequency YY-12SUB with two balanced line inputs and two balanced signal link outputs, one RS485 for signal input and one RS485 for signal link output, plus a power input and output port, fully meet the use of demand, but also convenient system expansion.

    With the high-performance DSP digital audio signal processor, various scene parameters can be set according to different application requirements and different number of speakers. The parameters can be adjusted synchronously by control software with more than RS485 modules, and the parameters can be quickly adjusted by shortcut keys, which greatly simplifies the system construction process. The full-frequency Channel and ultra-low-frequency channel can adjust the size proportion independently, can achieve the best results in a very short time.

    The power amplifier module uses high efficiency Class D power amplifier circuit design, uses the L type heat dissipation patent design to combine with the integral cast aluminum back plate which has the heat dissipation function, therefore has the very high energy efficiency, the power reaches 400W + 400W + 1200W, at the same time, compact volume, stable performance.

    Through advanced system design, world-class Speaker units are selected and the system parameters are optimized through DSP and power amplifier modules, to ensure that the system in the sound effect, power, projection angle and distance, system stability and durability are very good performance, to ensure that the effect of a variety of different installation and use of full consideration in place, it is convenient to transport, install, debug, expand and combine, and can fully meet the needs of small and medium-sized performances.
