Digital signal processor is shared for performing first mixer processing that mixes audio signals from input channels via mixing buses and then outputs resultant mixed audio signals to first output channels and second mixer processing that mixes the audio signals from the first output channels via matrix buses and then outputs resultant mixed signals to second output channels. The processor performs each of the first and second mixer processing by performing cross-point processes each for performing level control on an input signal and then adding a resultant level-controlled signal to one or more of the buses, a total number of the cross-point processes simultaneously executable by the processor being limited. Setting of the numbers of the mixing and matrix buses is controlled such that a sum of the numbers of first and second cross-point processes required for the numbers of the mixing and matrix buses set by a user respectively.
