Unboxing and Package Contents
Upon receiving your Onn Soundbar, carefully inspect the packaging for any signs of damage during transit. Once confirmed safe, open the box and verify all components are present. You should find the Onn Soundbar unit itself, the power adapter, and the remote control.
Depending on whether you purchased a bundle, you may also find the Onn Roku Wireless Subwoofer included. A quick start guide and safety instructions are also essential inclusions within the packaging. It’s crucial to retain the original packaging for potential returns or warranty claims.
Carefully remove all protective materials from the soundbar and accessories. Ensure no foam inserts or plastic wrappings remain. A visual inventory against the included documentation will confirm you have everything needed for a successful setup. Contact customer support immediately if any items are missing or damaged.
Soundbar Placement and Ventilation
Optimal Onn Soundbar performance relies on strategic placement. Position the soundbar directly facing the listening area, ideally centered beneath your television. Ensure a clear line of sight between the soundbar and your seating position for the best audio experience. Avoid placing the soundbar inside enclosed spaces like cabinets, as this can muffle the sound.
Ventilation is critical; Allow at least 4 inches of space around the soundbar, particularly on the sides and rear, to prevent overheating. Do not cover the soundbar with any materials, such as curtains or blankets. Proper airflow ensures the longevity and consistent performance of your device.
Avoid areas exposed to direct sunlight, excessive moisture, or extreme temperatures. Stable, level surfaces are essential to prevent accidental falls and potential damage. Consider wall mounting using appropriate hardware (not included) for a cleaner look and enhanced sound projection.
Connecting the Power Adapter
Before connecting the power adapter, ensure your television is turned off. Locate the DC IN port on the rear panel of your Onn Soundbar. Carefully insert the provided power adapter plug into this port. Then, plug the adapter itself into a standard wall outlet.
Verify the outlet is functioning correctly by testing it with another device. Do not use any other power adapter than the one supplied with your soundbar, as this could cause damage or malfunction. The power adapter is designed specifically for this device’s voltage requirements.
Once connected, the soundbar may briefly illuminate or emit a sound indicating it’s receiving power. If the soundbar doesn’t power on, double-check all connections and the outlet. Avoid using extension cords or power strips if possible; a direct wall connection is recommended for optimal performance and safety.

Initial Setup and Powering On
After securely connecting the power adapter, the Onn Soundbar is ready for initial setup. Press the power button located either on the top of the soundbar or on the remote control. The soundbar will initiate its startup sequence, which may include a brief display of the Onn logo or a welcome message.
Allow a few moments for the soundbar to fully boot up. During this time, it may automatically attempt to detect previously paired devices or settings. If this is your first time powering on the soundbar, it will likely be in default mode, ready for connection to your TV or other devices.
Ensure the soundbar is placed in a suitable location with adequate ventilation, as described in the placement guide. Familiarize yourself with the basic functions of the remote control before proceeding to connect it to your television.
Connecting to Your TV: Optical Cable
For a digital audio connection, use an optical cable to connect your TV to the Onn Soundbar. Locate the “Optical Out” port on your TV – it’s typically labeled and covered by a protective flap. Similarly, find the “Optical In” port on the back of the soundbar.
Carefully insert one end of the optical cable into the TV’s Optical Out port and the other end into the soundbar’s Optical In port. Ensure the cable clicks securely into place. Once connected, power on both the TV and the soundbar.
On your TV, navigate to the audio settings menu. Select “Optical” or “External Audio” as the audio output source. You may need to adjust the TV’s volume settings to achieve the desired sound level. The Onn Soundbar should now receive audio from your TV via the optical connection.
Connecting to Your TV: HDMI ARC
HDMI ARC (Audio Return Channel) offers a simplified connection for superior audio quality. Locate the HDMI port labeled “ARC” on your TV. Connect one end of an HDMI cable to this ARC port; Then, connect the other end to the HDMI ARC port on the back of your Onn Soundbar.
Power on both your TV and the soundbar. On your TV, access the audio settings menu and enable “HDMI ARC” or “ARC” as the audio output. Some TVs may automatically detect the ARC connection. Ensure that the soundbar is set to the correct HDMI input source.

HDMI ARC allows audio to travel both ways through a single cable, simplifying setup and potentially enabling control of the soundbar’s volume using your TV remote. Enjoy enhanced audio performance with this convenient connection method.
Bluetooth Pairing with Devices
To connect wirelessly, activate Bluetooth pairing mode on your Onn Soundbar. Press and hold the Bluetooth button on the soundbar or use the remote control to initiate pairing. The soundbar will become discoverable to nearby Bluetooth devices.
On your smartphone, tablet, or other Bluetooth-enabled device, navigate to the Bluetooth settings menu. Scan for available devices and select “Onn Soundbar” from the list. You may be prompted to enter a pairing code; if so, try “0000” or consult the user manual.
Once paired, your device will connect automatically whenever it’s within range. Enjoy streaming music or audio from your favorite devices wirelessly. Remember to maintain a stable Bluetooth connection for optimal audio quality.
Using the Onn Remote Control
Your Onn Soundbar comes equipped with a dedicated remote control for convenient operation. Ensure the remote has fresh batteries installed for optimal performance. Point the remote directly at the soundbar’s front panel for reliable signal transmission.

The remote allows you to power the soundbar on/off, adjust volume levels, select input sources (Optical, HDMI ARC, Bluetooth), and navigate sound settings. Utilize the dedicated buttons for quick access to frequently used functions.
Explore the equalizer presets to customize your audio experience. The remote also facilitates subwoofer control, allowing you to adjust bass levels to your preference. Familiarize yourself with each button’s function for seamless control of your Onn Soundbar.
Understanding the Remote Control Buttons
The Onn Soundbar remote features several key buttons. The Power button initiates on/off functionality. Volume Up/Down controls adjust the audio level. Input selection buttons (Optical, HDMI ARC, Bluetooth) cycle through available sources.
The Mute button silences the audio output. EQ buttons access preset equalizer settings for customized sound profiles. Subwoofer level controls adjust the bass intensity. Navigation buttons (arrows) are used within menus.
The OK/Select button confirms selections. A Menu button accesses the soundbar’s settings. The Bluetooth button initiates pairing mode. Note that the remote cannot operate as a hands-free device. Understanding each button’s purpose ensures effortless control over your soundbar’s features and settings.
Adjusting Volume and Sound Settings
Volume Control: Use the Volume Up and Volume Down buttons on the remote to adjust the sound level. Ensure the soundbar isn’t muted (check the Mute button). Adjustments can also sometimes be made directly on your TV using its remote, depending on the connection type (HDMI ARC).
Sound Modes: Explore preset sound modes via the EQ button on the remote. These modes (Movie, Music, News, etc.) optimize audio for different content. Experiment to find your preferred setting.

Subwoofer Level: Fine-tune the bass by using the Subwoofer Level buttons. Increase for more impactful bass, or decrease if it’s overpowering. Remember to consider subwoofer placement for optimal results. Adjusting these settings allows you to personalize the audio experience to your preferences and room acoustics.
Equalizer Settings and Customization
Custom EQ Profiles: While the Onn Soundbar offers preset sound modes, some models allow for customized equalizer (EQ) settings. Access these through the soundbar’s menu, typically navigated using the remote control.
Frequency Adjustment: Within the EQ settings, you can often adjust specific frequency bands (bass, mid-range, treble). Increasing a band boosts those frequencies, while decreasing lowers them. Experiment carefully to avoid distorting the sound.
Personalized Sound: Tailor the sound to your preferences and the acoustics of your room. For example, boost bass in a large room or reduce treble if the sound is too harsh. Save your custom profiles for quick access. Remember subtle adjustments often yield the best results, creating a truly personalized audio experience.
Onn Soundbar and Subwoofer Pairing
Initial Connection: If you have the Onn Roku Wireless Subwoofer, pairing is usually automatic upon powering on both devices. Ensure both the soundbar and subwoofer are near each other during the initial setup. The soundbar will typically search for and connect to the subwoofer automatically.
Manual Pairing: If automatic pairing fails, consult your user manual for specific instructions. This often involves pressing and holding a pairing button on both the soundbar and subwoofer simultaneously. A visual indicator (LED light) will confirm a successful connection.
Troubleshooting: If pairing continues to fail, try resetting both devices. Ensure no other Bluetooth devices are interfering with the connection. Proper pairing delivers a richer, more immersive sound experience, especially for bass-heavy content.

Subwoofer Placement for Optimal Bass
Strategic Positioning: For the deepest, most impactful bass, avoid placing the Onn subwoofer directly against walls or in corners. This can amplify unwanted resonances and muddy the sound. Experiment with different locations within the room to find the sweet spot.
Floor vs. Elevated Surfaces: Generally, placing the subwoofer directly on the floor yields the best bass response. However, if your flooring is uneven or carpeted, slightly elevating it on a stable platform can sometimes improve clarity.
Room Acoustics: Consider your room’s acoustics. Soft furnishings like rugs and curtains can absorb bass frequencies, while hard surfaces reflect them. Adjust the subwoofer’s position accordingly to balance the sound. Proper placement significantly enhances the overall audio experience.
Troubleshooting Common Issues
No Sound? First, verify all cable connections (HDMI ARC, Optical) to both the soundbar and your TV. Ensure the TV’s audio output is set correctly to the connected port. Confirm the soundbar is powered on and not muted. Try cycling the power on both devices.
Bluetooth Pairing Problems? Clear the Bluetooth cache on your device and attempt pairing again. Ensure the soundbar is in pairing mode. Keep devices within a reasonable range (typically 30 feet). Interference from other wireless devices can sometimes cause issues.
Distorted Sound? Reduce the volume on both the soundbar and your TV. Check for any loose cables. If using the subwoofer, verify its connection and placement. A factory reset may resolve persistent audio distortions.

Remote Not Working? Replace the batteries. Ensure nothing obstructs the remote’s signal path to the soundbar.
Resetting the Soundbar to Factory Settings
Why Reset? Resetting your Onn Soundbar restores it to its original factory defaults, resolving software glitches, clearing saved settings, and potentially fixing performance issues. This is useful before contacting support or after significant configuration changes.
How to Reset: Locate the reset button – typically a small recessed button on the rear panel of the soundbar. Using a paperclip or similar object, press and hold the reset button for approximately 10-15 seconds. The soundbar will power off and then automatically restart.

Confirmation: During the reset process, you may observe a brief visual indicator (like a flashing light). Once restarted, all custom settings, including Bluetooth pairings, equalizer adjustments, and input selections, will be erased. You’ll need to reconfigure the soundbar from scratch.
Caution: This process is irreversible, so back up any critical settings if possible.
