Sound mixing console with master control section

Abstract

A sound mixing control console, having a plurality of audio signal input channels, includes a master channel control section having a plurality of motorized knobs for adjusting various parameters of an audio signal. The master channel control section can be applied to any one of the audio signal input channels to allow an operator to adjust any of the various parameters of the signal including, for example: input gain, frequency equalization (tone controls), placement in stereo (pan), and output level. All of the aforementioned parameters for any single input channel can be store for later recall. The various stored parameters for each input channel correspond to positions of the various knobs provided in the master channel control section. When any single input channel is selected for adjustment and signal processing parameters have previously been stored for that channel, the motorized knobs of the master channel control section are driven quickly to positions that correspond to the stored parameters. The various parameters can then be re-adjusted as desired and stored either as a new group of settings or re-stored to replace the original group of settings.
