You can connect your televisions optical audio port from the TV to the Optical In.
If your television only has analog outputs (RCA, red and white), then you can use an RCA cable and play your TV's audio through your system with the AUX-IN input.
Directions on connecting a television to your Home Theater system can also be found starting on Page 20 of the Owner's Manual.
