Hi Penny! The HW-A430 will connect to any TV supporting digital optical audio or Bluetooth wireless audio technology. If your TV supports one of these audio connections, you will be able to hear all sound from the TV through the soundbar. If your XBox can connect to the TV, you can use it with this soundbar.

Hi Wymanology! When both soundbar and subwoofer are plugged in, they should begin to connect automatically. When the subwoofer is completely connected, the blue LED LINK indicator on the subwoofer stops blinking and glows continuously. If the blue LED does not stop blinking, the process has failed.

For manual connection, after both soundbar and subwoofer are plugged in to a wall outlet, press and hold the ID SET button on the back of the subwoofer for at least 5 seconds. The red indicator on the rear of the subwoofer turns off and the blue indicator blinks.

Press and hold the Up button on the remote control for at least 5 seconds. The ID SET message appears on the display of the Soundbar for a moment, and then it disappears. The Soundbar will automatically power on when ID SET is complete.

Check if the LINK LED is solid blue (connection complete). The LINK LED indicator stops blinking and glows a solid blue when a connection is established between the Soundbar and the Wireless Subwoofer.
