Single 18-Inch Line Array Sound System Active Ulf Speaker
YY series active frequency division mode, high power processing
capability, good sound quality, light weight, easy to operate
flight system, Beautiful Mesh Grid design
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
