Hi I do not know anything about circuits , but am in a need of a switch with multiple audio inputs , would like it to be automatic and also if possible to have manual control , where 8 or more (ideally up to 32 audio inputs) to be selected to go through the output , one by one in a loop for a preselected time each. also to be able to select and stay on one of the inputs at a time and the input ID to be shown on a display. any help is highly appreciated.
