How To Connect an ONN Soundbar To An Electrical Outlet?

Connecting ONN Soundbar to an electrical outlet is a relatively straightforward process. The ONN soundbars come with AC connectivity and you need to connect one end of the adapter to the AC IN port and the other end of the adapter to the power outlet.

Once the soundbar is connected to the power, press the power button on the soundbar or remote control to switch it ON. You will hear a prompt tone indicating that the device is powered on.

Installing And Wall Mounting Your ONN Soundbar

Installing the ONN Soundbar on the wall involves drilling holes and using screws to securely mount the device. This process requires precision and knowledge about wiring and plumbing to prevent any potential damage to the device or injuries. 

Start with drilling two holes parallel to each other on the wall (around 100mm each) and keep a distance of around 58mm between the holes.

Now, attach your soundbar to the wall but avoid over-tightening the screws. You must use an electronic stud finder to determine the wall type before starting the drilling or mounting process.

If you’re not comfortable with this, it’s recommended to hire a professional for the installation.

Remember, the wall must be strong enough to support the weight of the soundbar. 

Solid walls such as concrete, brick, or solid wood battens are ideal. Plaster walls, drywall, and lath walls may not be sturdy enough for mounting the Soundbars.
