3. Setup
3.1 Unboxing
To safely unbox your Command Bar, lay the product box on its side. Release the tabs and slide out the contents. All necessary components for setup are included within the packaging.
3.2 Connecting to Your TV
The Command Bar can be connected to your television using either an HDMI cable (recommended) or an Optical cable.
- HDMI ARC Connection (Recommended): Locate an HDMI input on your TV labeled "ARC" (Audio Return Channel). Connect one end of the provided HDMI cable to this port on your TV and the other end to the "TV (ARC) HDMI OUT" port on the Command Bar. HDMI ARC allows for high-quality multi-channel audio and enables control of the sound bar using your TV's remote via CEC (Consumer Electronics Control).
- Optical Connection: If your TV does not have an HDMI ARC port, connect one end of the provided Optical cable to your TV's optical audio output and the other end to the "TV OPTICAL" input on the Command Bar.
For detailed information on your TV's HDMI ARC or CEC compatibility, consult your television's owner's manual.
3.3 Power Connection and Subwoofer Pairing
- Position the Command Bar and connect its power adapter to an AC outlet.
- Position the wireless subwoofer and connect its power cord to an AC outlet.
- Once both units are plugged in and powered on, the Command Bar and subwoofer should automatically pair within approximately 30 seconds.
- To verify successful pairing, check for a solid green "BAR SYNC" light on the back of the subwoofer. If the light is not solid green, refer to the Troubleshooting section or the Quick Start Guide for pairing instructions.
4. Operating Instructions
