Moreover, along with our country reform and open policys advancement, the society develops gradually to the information society, the living standards had the very big enhancement, the electronic technologies in have worked not only and in the study indispensable, even, day by day it was also important in the entertainment life, more and more people enjoyed the electronic informationization the modern life to take to peoples pleasure, like sang, watches the movie, recorded song and so on. At this time, We cannot leave an important thing——The Mixer, for this reason, proposed “multiway switch type mixer” the task of design, made us even more to understand mixers application principle, better application in life. The multiway switch type mixer is that put the multi-channel audio frequency signal mix into 1 group output, compare to the mixes sound directly, it has the confusion to be young, the low distortion, mixes the sound clearly and so on merits. Manufactures the multiway switch type mixer, I use the Multi
