Abstract: An audio mixer includes an operation panel that includes a plurality of physical controllers that control a value of a parameter. The audio mixer has a signal processor that processes an audio signal to be outputted from a plurality of input channels to a plurality of mixing buses according to the value of the parameter, and a processor that controls an operation of the signal processor. The plurality of physical controllers include a first physical controller that controls a value of a first parameter and a second physical controller that controls a value of a second parameter. The processor, in a first mode, divides the plurality of input channels into a first input channel of a first signal processing system and a second input channel of a second signal processing system different from the first signal processing system, divides the plurality of mixing buses into a first mixing bus of the first signal processing system and a second mixing bus of the second signal processing system, controls the signal processor to perform a first operation to process an audio signal to be outputted from the first input channel to the first mixing bus according to the value of the first parameter in the first signal processing system, and controls the signal processor to perform a second operation to process an audio signal to be outputted from the second input channel to the second mixing bus according to the value of the second parameter in the second signal processing system, in a second mode different from the first mode, controls, by using the plurality of input channels and the plurality of mixing buses as part of the same signal processing system, the signal processor to perform a third operation to process an audio signal to be outputted from the plurality of input channels to the plurality of mixing buses according to the value of the first parameter and the value of the second parameter in the same signal processing system.
