Managing inputs
If you connected external audio source components (like CD players, portable music players, Cable Boxes, etc...) to any of your HEOS devices inputs, you can rename the default input names to describe the actual source or hide any inputs that are not being used.
Select the Settings icon located in the upper left corner of the main “Music” menu to display the Settings menu.
Select “Music Sources”.
Select “Inputs”.
Select the HEOS devices which you connect your external audio source device to.
