These are all for our CG strong and power 4 channels class AB amplifier.

For this series,we have RMS 4*120W  4*150W and 5 channels 4*120w+1*500w.
 
Look at this 4*120w,the net weight is 3.65 kg,and if with foam,package it will arrive 4.5 kg/ctn.For common/ordinary similar power 120w,the basic model weight about 2.2 kg,so it is much heavier than other options.
 
Then some may wonder why we make is so big and heavy?
 
1) the first reason is because it is class AB amplifier,as we know the efficiency is about 65-70% so some of some of the energy is dissipated in the form of heat .and after continuous playing the surface will get very hot even shutdown to protect the amplifier from damaged.
 
Then how to solve this problem?
 
Obvious we make bigger housing to let the heat heat dissipation come out and not accumulated.then the inner circuit board will be in safety specs and the surface will be not hot.
 
Maybe you will wonder,since the shell is so big,then the price is much higher than common ones?yes what you are thinking is 50% right. This model is a little expensive,except the heavy heatsink,also the layout of inner board is good,and we make top and high quality electronic parts to ensure the excellent quality and performance of products.
 
If you try,you can compare with ordinary one,this sound is very warm and stereo surrounded.
 
Except the products itself,let’s check the package. Many clients pay much attention on the gift box,since good products also need good exterior decoration.you can find the box is strong,we especially made drop test for package before put it to mass production.Even after long time and distance of transportation,the box will bear and not broken.
 
Well,the above is the basic features for it.then we can conclude the following advantages for this series:
 
1) Big size, good heat-dispassition performance.
 
2) excellent sound quality, it is powerful ;
 
3) Package good and strong.

These are all for our CG strong and power 4 channels class AB amplifier.
 
The first part finished and let’s start with the second part.
 
Our main market is Southeast Asia, Middle east, USA and South America. We have so many models and different style and model suits different market. You know CE is basic for entrying European market.and we are ready to have each series of CE certificate.Factory has the ability to produce good things to meets the standard.
 
Saying here,I have to say that a series suitable to USA and market,it can pass
CISPR 32 and FCC Part15.
 
the size is small but power is big.
