ABSTRACT:
A sound mixing control console used in live concert performances, etc., includes a master control section having motorized knobs for controlling variable parameters such as input gain, pan, frequency equalization and the like of individual input channels. Each of plural input channels includes a dedicated fader for controlling output level and a selector switch for applying the master control section to that channel for controlling other variable parameters besides output level. A memory subsystem stores and recalls the positions of the motorized knobs. When an input channel is selected, the knobs of the master control section assume positions corresponding to the current values of the variable parameters, which may then be adjusted manually and stored. Signal processing is carried out by digitally-controlled circuitry.
