ABSTRACT:
An audio system has menu-driven controls using a select button to scan through possible functions and uses up and down adjustment buttons to modify the selected function. The menu of selected functions is automatically altered according to the presence of front and rear speakers to avoid any confusion from presenting a fade function on the menu when in fact there are not both front and rear speakers connected to the system.
