Abstract:
1. A digital mixer which selectively delivers a plurality of externally-input signals to plural buses of a mixing bus section to perform mixing on the input signals by each of the buses of said mixing bus section and selectively outputs mixed signals, said digital mixer inputting multi-channel surround signals as the externally-input signals, controlling levels of the externally-input signals, to be delivered to the mixing bus section, according to a surround channel configuration of said mixing bus section and localizing positions, and forming the mixed signals as multi-channel surround signals by said mixing bus section, wherein the surround channel configuration of said mixing bus section is more than four surround channels and the multi-channel surround signals formed by said mixing bus section have the same configuration as the surround channel configuration of said mixing bus section, said digital mixer comprising: an output section having a plurality of monitoring output channels, the plurality of monitoring output channels corresponding to the surround channel configuration of said mixing bus section; and a selection section that is operable to select a monitoring option of converting a configuration of the multi-channel surround signals, which are input externally, in accordance with said surround channel configuration of said mixing bus section, supplying said output section with the multi- channel surround signals having been input externally and having the converted configuration, and thereby realizing monitoring of the multi-channel surround signals, which have been input externally, via said output section, without passing through the mixing bus section, wherein said selection section is also operable to also select another monitoring option of supplying said output section with the multi-channel surround signals formed by said mixing bus section and thereby realizing monitoring of the formed multi-channel surround signals via said output section.
