-> AD-8300 is protected against excessive operating temperature, shorted speaker connections, ground faults, and other common fault conditions.

-> The Amplifier has overheat protection, DC protection, short circuit protection, overload protection

-> For the high-frequency transformer used on the power supply: It has overheat protection, overload protection, short protection, over-voltage protection, and under-voltage protection

-> Fan: The speed of the fan is determined by the temperature within the unit. At lower temperatures, the fan will be off, When the temperature increases the fan will auto-detect and increase the speed to control the temperature of the unit
