Claim:
An audio mixer comprising: a plurality of channels that process audio signals; a plurality of mixing buses provided as destinations of respective ones of the audio signals of said plurality of channels; a plurality of fader operators each provided for a different one of said plurality of channels, said plurality of fader operators being operable to adjust levels of the respective audio signals of said plurality of channels; a send level adjustment section provided, for each of the channels, in corresponding relation to said plurality of mixing buses, for adjusting the levels of the audio signals to be sent from individual ones of said channels to individual ones of said mixing buses; a plurality of bus selection switches provided in corresponding relation to said plurality of mixing buses; a bus selection section that, in response to operation of any one of the plurality of bus selection switches, selects one of said plurality of mixing buses that corresponds to the operated bus selection switch; a mode setting section that, in response to operation of the bus selection switch corresponding to the currently-selected mixing bus, switches, in a toggle fashion, an operation mode of each of the fader operators between an ordinary mode, where the level of the audio signal is adjusted by use of the fader operator, and a special mode, where a parameter of the send level adjustment section is set by use of the fader operator, wherein, in response to operation of any one of the plurality of bus selection switches that selects a mixing bus different from the currently-selected mixing bus, said mode setting section maintains the currently-set ordinary mode or special mode; and a control section that, in the ordinary mode and in response to operation of the fader operator, adjusts the level of the signal of the channel corresponding to the operated fader operator, and, in the special mode and in response to operation of the fader operator, adjusts the send level of the signal to be sent from the channel, corresponding to the operated fader operator, to the mixing bus selected by said bus selection section.
