Hello Rachel,
If available, we recommend using the HDMI connection to your TV.
Connecting your soundbar to a TV through HDMI will provide the best audio and user experience, often eliminating any connection or delay issues you may be experiencing. There are 2 ways to connect your soundbar with HDMI: you can connect a device to your soundbar (like a Blu-ray player) and then connect the soundbar to the TV, or you can use HDMI ARC. The first method will give you the best possible sound from external devices you regularly use. ARC is the way to go if you want great sound from streaming apps on your TV and a soundbar.
When powered on for the first time, the rear speakers and subwoofer should automatically connect wirelessly.
Please know you also have the option to connect this soundbar using Bluetooth, Optical, or Wi-Fi.
