each of the two outputs. Switching can be accomplished conveniently in any of three ways:

Manually, using the front panel pushbuttons that cycle through the four inputs
Remotely, using the supplied IR remote control

Regardless of how the unit is controlled, the user’s input selection is confirmed on the front-panel 

LED indicators for each of the two outputs.
