5. Connection
5.1 Dolby Atmos
Dolby Atmos gives you an immersive audio experience with sound in three-dimensional space, with rich, clear, and powerful Dolby sound. For more information, visit dolby.com/technologies/dolby-atmos.
5.2 DTS:X
DTS:X, the boundary of sound is no longer limited by the placement of speakers or the signal of specific channels.
To use Dolby Atmos / DTS:X
Dolby Atmos / DTS:X and HDMI eARC/ARC. For details on connection, see the HDMI connection section "HDMI eARC/ARC".
- To use Dolby Atmos® / DTS:X mode, your TV must support Dolby Atmos® / DTS:X and HDMI audio passthrough.
- Make sure that "Bitstream", "RAW" or "No Encoding" is selected for the audio output of the connected source device (e.g., Blu-ray/DVD player, TV, etc.).
- When Dolby Atmos / DTS:X / Dolby Digital / PCM format is input, the soundbar will display DOLBY ATMOS / DTS:X / DOLBY AUDIO / PCM AUDIO.
5.3 Using the HDMI connection
Some 4K HDR TVs have HDMI inputs that may need to be set up to receive HDR content. For additional details on setting up HDR screens, refer to the manual for your TV.
Use HDMI to connect the soundbar, AV equipment, and TV:
Method 1: Standard HDMI
- If your TV does not support HDMI ARC, connect your soundbar to the TV via a standard HDMI connection.
- Use an HDMI cable to connect the HDMI OUT (eARC/ARC) port on the soundbar to the HDMI IN port on the TV.
- Use an HDMI cable to connect the HDMI IN port on the soundbar to your external device (e.g., game console, DVD player, or Blu-ray).

Method 2:
eARC (Enhanced Audio Return Channel) / ARC (Audio Return Channel)
The eARC or ARC function allows you to send audio from your TV to the soundbar if it is compatible with ARC or eARC via a single HDMI connection. To use the ARC or eARC function, make sure your TV supports HDMI-CEC and ARC or eARC and is set up accordingly. When properly set up, you can use your TV remote to adjust the sound output (VOL +/− and mute) of the soundbar.

Connect an HDMI cable from the HDMI OUT (eARC/ARC) port on the soundbar to the HDMI (eARC) or HDMI (ARC) port on your TV that supports eARC or ARC. Then use the TV remote to select HDMI eARC or HDMI ARC.
Cobetn:
The TV and the device are connected via HDMI-CEC and the ARC or eARC function. HDMI-CEC and ARC or eARC must be set to On. The setting method for HDMI-CEC and ARC or eARC may vary depending on the TV. For details on the ARC and eARC functions, refer to the user manual. - ARC works only with devices that have HDMI ARC and with HDMI 1.4 cables (or newer).
5.4 Using the OPTICAL connection
- Connect the optical cable to the OPTICAL OUT on the TV and the OPTICAL on the device.

5.5 Connecting the AUX input
A. Use an RCA to 3.5 mm audio cable to connect the audio output on the TV to the AUX input on the device. B. Use a 3.5 mm to 3.5 mm audio cable to connect the AUX input on the TV or an external audio device to the AUX input on the device.

5.6 Power connection
- Risk of electric shock! Make sure that the mains voltage matches the voltage indicated on the rear panel of the device.
- Before connecting the power cable, make sure you have completed all other connections. Subwoofer: Connect the power cable to the AC IN on the main unit, then to the mains outlet. Subwoofer: Connect the power cable to the AC IN on the subwoofer, then to the mains outlet.

*The length of the power cable and the type of plug may vary by region.
5.7 Pairing with the subwoofer
Automatic pairing
The subwoofer will automatically pair when it is plugged into the mains and turned on.
No connection cables are needed between the two units.
- Status of the indicator on the wireless subwoofer.

| Бавно Трека | Поврзуваtheses / с nanopуваtheses не усnea |
Notes:
- Do not press the button PAIR on the rear side of the subwoofer, except for manual pairing. If automatic pairing does not succeed, manually pair the subwoofer with the main unit.
Manual pairing
- Ensure that the cable is well connected and the main unit is in standby mode. 2. Press the button on the main unit and the remote control to turn on the main unit. 3. Press the button on the main unit and the remote control with the button to enter pairing mode. The screen will show "SW Pairing". 4.

- Once wireless connection succeeds, the pairing indicator will light up and the screen of the main unit will show "SW IN".
- If the pairing indicator blinks slowly, wireless connection has not succeeded. Unplug the subwoofer cable and then reconnect the main cable after 3 minutes. Repeat steps 1~4.
Notes:
If wireless connection succeeds again, check for any interference (e.g., interference from electronic devices) around your location. Remove any interference sources and repeat the above steps.
The subwoofer should be within 6 m (18 ft) of the soundbar in an open space. If the main unit is in on mode and not connected to the subwoofer, the subwoofer indicator will blink slowly. Follow steps 1~4 above to pair the subwoofer with the main unit.
