Setup
1. Unpacking and Placement

2. Connecting the Sound Bar and Subwoofer
The sound bar and wireless subwoofer are pre-paired at the factory. Simply connect the power cables to both units and plug them into a wall outlet. The subwoofer will automatically connect to the sound bar when both are powered on.
3. Connecting to Your TV
For the best audio quality, connect the sound bar to your TV using the supplied optical cable. Insert one end of the optical cable into the 'Optical Out' port on your TV and the other end into the 'Optical In' port on the sound bar.

Alternatively, you can use an analog audio cable (not included) if your TV does not have an optical output. Connect the analog cable from your TV's audio output to the 'AUX In' port on the sound bar.
4. Adjusting TV Audio Settings
After connecting, access your TV's audio settings menu. Disable the TV's internal speakers and set the audio output to 'External Speakers' or 'Optical/Digital Audio Out'. Ensure the digital audio output format is set to 'PCM' if available, as this is widely compatible.
Operating Instructions

Press the Power button on the remote control or on the sound bar to turn the system on or off. The sound bar will indicate its status with an LED light.
Volume Control
Use the Volume Up (+) and Volume Down (-) buttons on the remote or sound bar to adjust the overall system volume.
Voice Adjust Technology
The exclusive Voice Adjust Technology allows you to increase or decrease the vocal intelligibility independent of the master volume. Press the 'Voice Adjust' button on the remote and use the volume buttons to fine-tune dialogue clarity. This feature is particularly useful for movies and TV shows where dialogue can sometimes be difficult to hear over background effects.
