Breaking through the traditional design path and creating new technological limits in power/weight ratio and power/volume ratio.
Carefully selected materials combined with surface mount technology and specially designed transformers result in smaller volumes and higher power output.
Four dual DC infinitely variable speed fans are used for cooling, and complaints are made starting at 45 degrees Celsius to solve the problem of the fan whistling before singing in the private room.
Accurate over temperature, over-current, short circuit, ultra-high frequency protection, surge resistance, and switch on/off impact protection functions.
