A fader device used for an audio mixer etc. includes fader operators capable of being operated both manually and by a motor individually for each of plural channels, a signal processing circuit for applying a signal processing to an input signal of each channel in accordance with an amount of operation of a corresponding one of the fader operators, a fader operation mode switching circuit for switching a fader operation between a single operation mode and a group operation mode, and a control circuit for performing a fader control. In the single operation mode, each of the fader operators can be individually operated. In the group operation mode, operation of any one of a group of the fader operators causes other fader operators of the group to be compulsorily operated or to be driven automatically to positions corresponding to absolute amounts of fading in respective channels in accordance with an amount of operation of the one fader operator. Owing to such operation manner, the absolute amounts of fading in the respective channels can be readily recognized. |
