D series amplifier feature:
*Professional aluminum panel with two handle, convenience to move
*with advanced SMT technology, reduce solder defect, tidiness craft, lightweight
*Use Toshiba transistor, import small capacitor and high quality toroidal transformer
*Adopt three-grade class H high effect power supply, work temperature is lower, it make amplifier more stable.
*Special circuit: Output midpoint automatism ZERO adjust circuit, when without *DC output will automatism adjust circuit and project speaker
*Add special high temperature static state NTC circuit, amplifiers long time work more on stable.
*Perfect protect: Soft startup protect, short circuit protect, limited protect, high temperature protect, over load project
