PURPOSE:To decrease deterioration in a signal in each processing in the inside of an audio mixer by converting plural inputted audio analog signal into a digital signal and then applying mixing. CONSTITUTION:An audio-digital(A/D) converting mechanism 1 receives plural audio analog signals inputted externally and converts them into plural digital signals and transmits them, A digital signal input control device 2 controls respectively the plural digital signals converted and sent by the A/D converting mechanism 1. A digital signal mixing mechanism 3 combines the plural controlled digital signals mutually and the resulting signal is controlled by a digital signal output control mechanism 4. Thus, the plural inputted audio analog signals are converted into the digital signals at input and each processing is implemented without increasing the signal deterioration. |
