The top two rows of buttons on the RR-969 remote are not used to change sources on the Rotel device, they are used to select the various devices in your system that your RR-969 has been programmed to control.

To switch sources, first make sure you have selected the AUD device button on the top row of the RR-969. Then slide the drawer open on the remote, and the first two rows of buttons below the drawer will allow you to switch between the different inputs on the Rotel device.
