An audio multi-dubbing system includes an input switching part(11), amplifiers(20,30), a Hi-Fi detection part(40), a microcomputer(50), and a mixed processing part(60). The input switching part(11) possesses two input switches(12,13), in case of audio dubbing, this device selects L channel and R channel audio signals(L21,L2,R1,R2) and the input switch(12) selects one of the two L channel audio switches(L1, L2) inputted according to control of the microcomputer(50), outputs to the mixed processing part(60), and the input switch(13) selects one of the two R channel audio switches(R1,R2) inputted according to control of the microcomputer(50), outputs to the mixed processing part(60).
