1.stereo,mono,bridge,three different modes 
2.using a relay circuit to achieve power soft-start,thereby protecting the speaker from the impact of power 
3.all models hace a reliable boot delay,overload,over temperature,zero drift,such as multiple protection. 
4.Quad indepent input and output allowing you thoroughly. 
5.using high-capacity filter capacitor,high-low leakage fiux toroidal trasformer and high-qulity audio power output tube 
6.low-noise cooling fan close automatically disconnected when the temperature rose to 105°C output in order to protect machinery  
from damage,the temperature dropped to 85°C automatically return to work  
7.using the lastest technology to make noise to minium grounding.  |
