Patent ID: 8340324

Claim:
A device for setting parameters of a mixer which processes audio signals in a plurality of channels including input-type channels and output-type channels, comprising: a control panel for adjusting a parameter of each of the channels, said control panel being provided with controls including channel selecting switches assembled on the control panel, the channel selecting switches corresponding to each of the channels including the input-type channels and the output-type channels for selecting the channels; a first controller that sets a copy mode, the copy mode operable to perform a copy operation for input-type channels and a copy operation for output-type channels; a second controller, when the copy mode is set, that sets all the channel selecting switches on said control panel to valid for a parameter-copy operation; and a third controller, when an operation of a channel selecting switch of said channel selecting switches is detected while the copy mode is set, (a) in a case where the operation of the channel selecting switch is determined to be an operation to select a copy-source channel, that selects the channel corresponding to the operated channel selecting switch as the copy-source channel and sets the channel selecting switches corresponding to the channel of a different type from a type of the copy-source channel to invalid to thereby place only the channel selecting switches corresponding to the channels of the same type as the copy-source channel into a valid state, and (b) in a case where the operation of the channel selecting switch is determined to be an operation to select a copy-destination channel, that selects the channel corresponding to the operated channel selecting switch as the copy-destination channel.
