Gisen is a comprehensive enterprise which developes, produces, sells and services independently. Not only we have a young, pioneering, innovated and specially hardworking team, but also a strict operation system. We always require better when we research and develop our products and services. In these years, products with Gisen characteristics come out continuously by the constant effort of our staff.

As the high demands of power amplifer on various occasions, especailly on a recreational one, Gisen power amplifier has adopted an effective radiator system and a throughly considered protections of circuit: With a built-in clip limiter(which strenghthens the protection of the loudspeaker), protections on direct current, hypo-low frequency loudspeaker and overheating, and a smart temperature-manipulative system which can adjust the temperature when it changes. So that the amplifier would still work in the state of being stable no matter there is a short current, a long-time overloaded woring time or an abnormal increaseing input signal.

Every product of GISEN is made of well-chosen articles under the idea of circuit-module design and SMT(Surface mounted technology) process. Its distinctive and perfect protection system, excellent capability and outstanding timbre make it stand out from the crowd and it gains its reputation in its field.

Now GISEN PRO amplifiers of two-channel, three-channel, four-channel, five-channel have been widely used in situations like KTV, HI room, Rock room, conference, and performance. And GISEN will, under the tenet of "Quality, Service, and Innovation", keep improving and advance with the times in pursuit of best quality. Also we hope that there would be more sincere interaction with you which benefits both and we can build a bright future together!
