Patent ID: 8254599

Claim:
A mixer apparatus comprising: normal input terminals that input normal sound signals of a plurality of normal input physical channels; a plurality of mixing buses that perform mixing processing on sound signals; a cascade input terminal that inputs cascade sound signals of a plurality of cascade input physical channels; an input logical channel setting section that selectively assigns the normal and cascade input physical channels to a plurality of normal input logical channels and a plurality of cascade input logical channels, individual ones of the cascade input logical channels being associated with particular mixing buses; an input patch section that sets correspondence relationship between individual ones of the plurality of normal input logical channels and individual ones of a plurality of input mixing channels; and an input processing section that performs equalizing processing on sound signals supplied in correspondence with the individual ones of the plurality of input mixing channels, and that sends the sound signal of each of the input mixing channels, having been subjected to the equalizing processing, to one or more desired mixing buses among said plurality of mixing buses, wherein the normal and cascade sound signals of the normal and cascade input physical channels, input via the normal and cascade input terminals, are supplied to the plurality of normal and cascade input logical channels in accordance with assignment by said input logical channel setting section, and the sound signal supplied to each of the normal input logical channels is delivered to the plurality of input mixing channels in accordance with setting by said input patch section while the sound signals supplied to the cascade input logical channels are supplied to the particular mixing buses corresponding to the cascade input logical channels.
