Using HDMI to connect the soundbar, AV equipment and TV:

Method 1: ARC (Audio Return Channel)
The ARC (Audio Return Channel) function allows you to send audio from your ARC- compliant TV to your soundbar through a single HDMI connection. To enjoy the ARC function, please ensure your TV is both HDMI-CEC and ARC compliant and set up accordingly. When correctly set up, you can use your TV remote control to adjust the volume output (VOL +/- and MUTE) of the soundbar.

Connect the HDMI cable (not included) from unit’s HDMI OUT (ARC) socket to the HDMI (ARC) socket on your ARC compliant TV. Then press the remote control to select HDMI ARC.

Tips:

Your TV must support the HDMI-CEC and ARC function. HDMI-CEC and ARC must be set to On.
The setting method of HDMI-CEC and ARC may differ depending on the TV. For details about ARC function, please refer to the owner’s manual.

Method 2: Standard HDMI

If your TV is not HDMI ARC-compliant, connect your soundbar to the TV through a standard HDMI connection.

Use an HDMI cable (not included) to connect the soundbar’s HDMI OUT (ARC) socket to the TV’s HDMI IN socket.
Use an HDMI cable (not included) to connect the soundbar’s HDMI IN (1 or 2) socket to your external devices (e.g. games consoles, DVD players and blu ray).
