Patent ID: 8744096

Claim:
A digital audio mixer comprising: a plurality of channels each of which controls a level of a supplied audio signal on a basis of a level parameter and outputs the level-controlled audio signal; a plurality of fader controls to which are allocated the plurality of channels, on channel per fader control, each of said fader controls being slidingly operable one-dimensionally from a first end to a second end of a movable range thereof and drivable on a basis of a drive signal; a level change section which, in response to a position of each of said fader controls, changes a value of the level parameter of a channel, allocated to the fader control, in such a manner that the value of the level parameter of the channel becomes greater as the position of the fader control approaches said first end and becomes smaller as the position of the fader control approaches said second end, wherein the value of the level parameter at the second end is set to a zero level value; a mixing bus which mixes a plurality of audio signals output from the plurality of channels to thereby output a resultant mixed audio signal; a main output section which outputs, to outside said digital audio mixer, the resultant mixed audio signal output from said mixing bus; a monitoring output section which outputs an audio signal designated as a cue signal; a resistance force generation section which, once any one of said fader controls is operated toward said second end within a predetermined range provided near said second end, drives the one fader control on the basis of the drive signal to thereby generate resistance force against operation of the one fader control, wherein said level change section changes the value of the level parameter within a range closer to said first end than the predetermined range and maintains the value of the level parameter at the zero level value as long as the position of the fader control is within a range from the predetermined range to said second end; a first control section which, once any one of said fader controls is operated toward said second end beyond the predetermined range, designates, as the cue signal, the audio signal of the channel allocated to the one fader control; and a second control section which, once any one of said fader controls is operated toward said first end beyond the predetermined range, cancels designation, as the cue signal, of the audio signal of the channel allocated to the one fader control.
