In a digital mixer, a storage stores operating data including a plurality of parameters for controlling states of audio signals of a plurality of channels. A signal processor performs a mixing process of the audio signals based on the operating data. A plurality of channel strips are mounted on an operating panel in correspondence to the plurality of the channels. Each channel strip includes operators arranged for controlling a corresponding channel. A display controller displays a panel imitation portion imitating an appearance of the operating panel and including a plurality of channel strip imitation images which imitate the plurality of the channel strips and which are arranged in a positional relationship corresponding to a positional relationship of the channel strips arranged on the operating panel. A parameter setter sets a value of a specific parameter of a channel corresponding to a channel strip upon detecting that the channel strip has been manipulated. A display mode setter allows each channel strip imitation image to be displayed in a display mode according to the value of the specific parameter of the corresponding channel.
