In a system capable of outputting an audio signal as beams from an array speaker and performing multi-channel reproduction, a plurality of beam setting patterns (reproduction modes) are stored in the memory of a controller. The beam setting patterns include a single basic pattern and a plurality of deformed patterns that use the beam control data of the basic pattern. When the user specifies a reproduction mode via an interface, the beam setting pattern corresponding to the mode is read and set to the signal processor of each channel.
