Specifications:
3U standard height, humanity design of large power with perfect combination of double ring type transformer and LH amplifier. Working efficiency of whole machine up to 80%. Using two groups of power supply, making the machine work under low voltage when the small signal coming; and switch over to high voltage automatically before big signal comes, which maximum enhanced working efficiency, highly improved reliability of machine. The machines input sensitivity can be chosen from 0.77V/1.4 and 26dB. Can be suitable for output of all kinds of signal source without any other process of relative equipments. Setup parallel mode under traditional pattern. Can make the machine continuous working under 2 OHMS. The parallel power equals the power of bridge at the same time, improving the using efficiency of machine notably. Automatic clip limiter protection, not only guaranteed high quality sound, but also reducing the damage to expensive speaker while system overload at the same time. Intellectual fan cooling system: Low noise with saving design, long working life, reducing the dispersed noise and dust pollution. Slow start circuit, using material of original Germany SIEMENS, guarantee the effect of on-off delay of machine, avoiding the whole system from assault of switching machine.
