PROBLEM TO BE SOLVED: To provide a digital mixer unit controlling the signal processing characteristic of an input channel signal processing means by reading the history of a selected channel with a simple operation, and treating the readout channel as edition channel. SOLUTION: A digital mixer selects channels assigned to channel strips 3<SB>1</SB>-3<SB>24</SB>from among a plurality of channels belonging to a layer selected by layer selection switches 4a-4e by means of selection switches 3b<SB>1</SB>-3b<SB>24</SB>. The selected channels are retained in a history table. Whenever a history readout switch 6 is depressed, the channel history is read out. The readout channel is treated as edition channel. In a set state of a layer cooperation mode, the digital mixer selects the layer to which the readout channel belongs, and assigns each channel included in the layer to each channel strip 3<SB>1</SB>-3<SB>24</SB>.
