K series Amplifier is a kind of the Switch power Amplifier. It is very smart and light weight ( 2U)  with a high power efficiency ( can even reach to 4400w 8ohm ).
It is a multi-professional power amplifier, not only each channel has its own variable output voltage, and more kind of sensitivity selection, but also can be used as high-power amplifier using constant pressure. Due to its multi-ling flexible operational, it is especially suitable for the popular line array system, they can be regarded as a perfect atch.Complete Protection, advanced non-relay protection of the output circuit,responsive and reliable, in particular when it is open circuit load instructions, even a   number of speakers connected to the amplifier, whatever it is short circuit or open circuit load, it will reflects on the Amplifier front panel on a glance,  which provide the user another convenience.  To further  improve its reliability and durability, all input and output Block all adoptted the original (Neutrik),Utilizing the company's full range of (formerly Motorola) power output transistors. In E times , to chosen the switch power amplifier will be your wisest choice!
