It has short-circuit protection, over-current, over-heating, and anti-reverse protection to prevent total failure. When an overload occurs, the device reports the fault condition to the processor to protect itself from damage
It adopts copper DC connectors and barrier terminals. It can withstand high current without heating or damaging wires.
Classic appearance multi-function main knob. The main knob adopts a rotary encoder that is only used in high-end power amplifiers, which realizes 360-degree stepless tuning and a smooth one-key start and stop. The operation is simple and convenient by long pressing the switch.
