ABSTRACT:
An audio receiver or other electronic device having a number of controllable functions is provided with control apparatus in which mechanical parts have been substantially eliminated. An electrically controllable device is provided to control each function. Memory registers provide inputs to the electrically controllable devices. The controllable functions may be on-off, as for a particular signal source, or may be variable, as for volume, tuning and tone in a receiver. Input controls include a single level control for adjusting the levels of all of the variable functions, and switches to select the function to be adjusted. Control means such as a microprocessor scans the switches and level control for changes in level and/or functions selected and updates the memory registers accordingly. A display is provided of selected functions and level.
