You will need to insert one end of an optical cable into the back of your Aspect 2 Channel Compact Soundbar Soundbar and the other end into the device that you're connecting to.
Then select the optical button on your remote control. The LED indicator on the side of your Aspect Soundbar should now be white.
Please note: You may need to enable the optical feature on your TV. Please consult your TV's user guide. It is recommended to use the PCM option if available.
