Abstract:
1. A mixer apparatus comprising: a plurality of mixing buses that perform mixing processing on sound signals and are capable of inputting thereto sound signals via corresponding cascade input logical channels; a normal input terminal section that inputs thereto sound signals of a plurality of normal input physical channels; a cascade input terminal section that inputs thereto sound signals of a plurality of channels via a plurality of cascade input physical channels corresponding to the cascade input logical channels and that includes a plurality of connection pins each corresponding to any one of said plurality of cascade input physical channels; an input signal processing section that performs equalizing processing on the sound signals supplied via the normal input logical channels corresponding to the normal input physical channels, and outputs the sound signals, having been subjected to the equalizing processing, to one or more desired mixing buses of said plurality of mixing buses; a model selection section that, in response to a user's operation, selects a supply source for supplying sound signals to be supplied to the cascade input logical channels; a cascade input pin conversion section that, 1) when a first supply source of a same model as said mixer apparatus is selected by said model selection section, supplies sound signals, inputted via individual ones of said connection pins, to the corresponding cascade input physical channels, and that, 2) when a second supply source of a different model from said mixer apparatus is selected by said model selection section, changes correspondency between the connection pins and the cascade input physical channels in accordance with a predetermined change rule and supplies sound signals, supplied via the respective connection pins, to the cascade input physical channels in accordance with the changed correspondency; an input assignment selection section that, when said second supply source is selected by said model selection section, optionally select, from among the plurality of normal input physical channels, normal input physical channels to be assigned to any of the cascade input logical channels and optionally select, from among the cascade input logical channels, cascade input logical channels the selected normal input physical channels are to be assigned to; an input assignment section that, 1) when none of the normal input physical channels is selected by said input assignment selection section, assigns the plurality of normal input physical channels to the corresponding normal input logical channels, and that, 2) when some of the normal input physical channels are selected by said input assignment selection section, assigns the selected normal input physical channels to the cascade input logical channels and assigns the cascade input physical channels, corresponding to the assigned cascade input logical channels, to the normal input logical channels corresponding to the selected normal input physical channels to thereby effect a mutual switching between the normal input physical channels and the cascade input physical channels; and a cascade sound signal supply section that supplies the sound signals, supplied via the plurality of cascade input logical channels, to the mixing buses corresponding to the cascade input logical channels.
