The main features are as the following: 
1. Class TD circuit designed specially for speaker connection covering from 2 ohms to 8 ohms
2. Compact inner component layout. .
3.  High working stability and efficiency.  
4. Carefully-selected components. Copper transformer.
5. Full selft-protection function of voltage limit and protection against over-load, over-heat, short-circuit,  switch on/off, RF interference   and mis-matched load.
5. Mechanical and automatic manufacture process of AI, SMD, PEAK, BACK-FLOW ,ensuring good quality consistency.  
6. Nice cooling system with quality radiation fin in ribbon shape with shovel teeth, achieving a higher heat dissipation effect.
