KS424
Model:KS424
size:
application:Conference room, multi-function lecture hall, stadium, bar, slow rocking bar, KTV, theater
Advantage：
●With three modes of stereo parallel connection and bridge connection；
●With DC protection, overload protection, short circuit protection, overheat protection, voltage limit protection, andsoft start protection,the machine performance is safer；
●Adopting a large number of high-precision SMD devices and automated production processes, the product reliabilityis higher；
●Adopting high-efficiency voltage-stabilized switching power supply, high efficiency and light weight；
●TD-type circuit design, low heat loss, high efficiency, small size, and high power；
●Automatic variable speed fan, the fan runs at a low speed when the machine is cold to reduce the environmentalnoise, and when the machine is working and heating, the fan automatically increases, and the optimized heatdissipation system makes the machine performance more stable；
●Adopting the classic MJw21193/21194, the sound is more beautiful and the low frequency is more powerful
