Following features ensure an extraordinary stability
*cooler free from the rack instead of being wrapped with the heat-isolative gasket, the transistors can immediately release the heat without temperature difference between transistors, each transistor is in the same, shortest distance from the exit of cooling air and each one bears the equivalent output power contributing to a much better reliability.
*comprehensive and precise protection program avoiding embarrassing damage or mis-protection caused by mishandling.
*sourcing the on-playing music as signal then calculating the instant resistance of load based on real-time analysis of the output voltage and current when the resistor is less than 1.6 ohms, soft protection launches to limit the driving current and recovers current in 5ms after the failure removed. The relay is kept in connected through protection just avoid contact destruction.
*detection on the temperature of radiator and adapter at the same time, adjusting cumulative output power in continual sections, maintaining the normal output through the high-temp protection with little detectable change during performance
*independent detection on the signal-above 3KHz in the output. Once it exceeds 40v in 0.5s the protection program launches to lower the output below 40v to levitate the damage to hf drivers
*inspection on peak voltage value of supply power to eliminate the abnormal factors destructive to amplifying circuit and shut down the output to protect the systems when necessarily.

In the solution to linear amplifier based on linear amplifier supplyu, the following innovative technologies put the power-to-weight ratio and power-to-volume ratio to a new unexplored limit
*less heat loss due to accurate power allocation
*unique power supplying program lower the requirements of power supply.
*select material and appropriate production technology maximizing the turnout of adapter
*ideal radiator structure improving heat sinking so that a smaller and lighter radiator can dissipate heat for faster and more efficiently.
