LG soundbars

The fact that LG soundbars often come with a subwoofer already integrated into them is one of the finest things about these soundbars. And in the event that this is not the case, they will often link up with a wireless subwoofer that has an easy connection to the main unit.

They have been specifically engineered to deliver stereo surround sound to rooms ranging in size from small to medium. 

Soundbars, in contrast to televisions, which contain their speakers in a single enclosure, disperse them throughout the whole surface of the device. They can connect to a television, digital video recorder (DVR), or gaming console and give you an additional boost.

If you have just purchased the Subwoofer to go with your soundbar, there is no need for you to be concerned because the setup is not at all complicated and won’t take more than 10 minutes to complete.

It is extremely simple to link the two, and there is not much else that has to be carried out in order to bring about the connection. Therefore, this is the process that must be followed in order to link the two devices together.

If you are turning on both of your devices for the first time and they do not automatically connect, you may need to pair them together manually.

Manually Connecting The Soundbar To The Subwoofer

To manually connect the Soundbar and the Subwoofer takes a little bit of extra effort because it necessitates following a few extra steps. 

Despite this, the end outcome justifies all of the hard work. If you simply follow our guidelines in the order that they are presented below, you should be able to get it operational in no time.

Don’t get worried if the two devices still won’t link to one another; there are still some things that you can do to get them to link with one another. Here are some other approaches that you can take to see if they help you connect the soundbar and the Subwoofer to one another.

1- You Are Unable To Pair Your Devices Using The Automatic Procedure

If you are still unable to get your devices to pair with one another, you will need to use the manual procedure. Don’t be concerned. Even if the automatic pairing doesn’t work, you can still use the manual method. And this is the manner in which you can go about doing that:

Step1: First, turn down the volume on your soundbar to its lowest setting. Either the buttons on your soundbar or the remote control can be used to accomplish this task. 

If your soundbar has a prominent display, you will notice that its screen displays the words “VOL MIN.”The sound bar’s LED status indicator will consistently glow a single colour of red for models that only have half displays.

Step 2: On your remote, press and hold the “Mute” button for three seconds. If the issue continues, you can try to solve it by clicking the STOP button on your soundbar for the same amount of time.

If your soundbar has a full display, you will see a notification that says “WL RESET.” In addition, the steady red light that was present earlier will change to a blinking red light if you have a model with a partial display.

Step 3: Press the pairing button of your Subwoofer for 10 seconds. Release your hold when the light on your subwoofer flashes between red and green.

Note: If your Subwoofer is already flashing green light, you can skip this step and move on to the next. 

Step4: The fourth step is to unplug both of the devices. Disconnect your soundbar and Subwoofer from the source of electricity they both use.

Step 5: Reconnect both devices to their respective electrical outlets. Wait for the LED light on your Subwoofer to turn solid green before proceeding. As soon as it does, the two of your devices will automatically be connected together.

2- Interference With The Signal 

Suppose you have multiple wireless electronic equipments in your home that all use the same frequency. In that case, you may experience signal distortion in the middle of such a mixture of signals, and it is simple for data and connections to get misplaced.

The following are some instances of gadgets that may cause interference with the process of pairing:

  • Microwaves.
  • The use of baby monitors.
  • Other wireless speakers are also available.

If you are able to, please turn off these electronic devices for the time being. Also, make sure that you keep them turned OFF until you have successfully linked your LG soundbar and the Subwoofer.

3- Volume

Turning up the volume on your soundbar can prohibit it from linking to your Subwoofer, which is one of the things that can prevent the two devices from working together. Don’t bother asking me why. 

Just remember that When you are trying to connect them together, the volume on your soundbar needs to be turned down to a more steady level.

4- Obstacle Between Soundbar And Subwoofer

Make sure there is no barrier between the soundbar and the Subwoofer so that the wavelengths connecting them will not encounter any obstacles, and both systems will be able to pair with one another effortlessly.

While there are no specific dos and don’ts for installing these two devices, it is in your best interest to keep them in close proximity to one another at all times.

They should be no more than 15 feet apart, as this is the recommended minimum distance between them. Because the larger the distance between them is, the poorer the audio quality becomes.

However, if you are having problems connecting the two, consider moving them closer to each other (no more than five feet apart) and then retrying the pairing process.

5- Stop/Mute Button 

Another tip that you can try to connect these electronic items together is by disabling the Subwoofer’s volume control by pressing and holding the button for a few seconds. This will allow you to test the connection between the two devices. 

Then, also depress and hold down the button labeled “Stop” on your soundbar for a few seconds. This may assist the two devices in finding one another and establishing a connection with one another.

6- An Issue With A Flashing Light

When the LED light on the LG sound bar has stopped flashing, you should then power on both of the devices again.

7- Pairing

In addition to this, you are going to want to check to see that you’ve put your Subwoofer into pairing mode before proceeding with the next step. 

There ought to be a button on your Subwoofer that enables you to accomplish this task; Please take a few moments to press and keep your finger on the button to enable the Subwoofer to connect.

8- Unplug Everything And Then Plug It Back In

You can also try turning off both of the devices at the plug, putting them into standby for a short amount of time, and then turning them back on.This is another option available to you. It’s possible that this is the simple solution to the issue you’re having.

9- Plug Both Devices Into Power  

Connect both devices to a power source. Despite the fact that your LG soundbar and Subwoofer can communicate wirelessly with one another, you will still need to use wired connections and adapters to connect them to a power source.

Both of these devices must be plugged into a power outlet in order to function properly. Consequently, locate a socket that is free of charge and into which you can plug your devices.

Where Would You Recommend I Put My Subwoofer?

If you’ve just purchased an LG subwoofer, you’ll want to be sure you know where you should put it as soon as possible. You don’t want any subwoofer to be flush against the wall; if at all possible, place it a few inches away from the wall instead.

The sounds that you play through the Subwoofer will then reflect off of the walls in your home when you play them. 

Many individuals decide to position their Subwoofer exactly below the TV, either slightly to the left or to the right of the center of the screen. However, you are not limited to placing your substitute in just this one spot.

Another excellent location for a subwoofer is in one of the room’s corners, provided that it is still only a few inches away from the adjacent wall. 

This may make it possible for the Subwoofer to produce an even greater amount of sound and maybe the method that yields the highest loudness from your Subwoofer.

When it comes to your Subwoofer and your main unit, you don’t want there to be too much space in between them.

If you are utilizing a wireless sub, this is very important to keep in mind because the better your connection will be, the closer it is to you.

In spite of the fact that the two locations shouldn’t be immediately adjacent to one another, a spacing of at least a few feet between them is recommended. In addition, it is essential to check that there are no intervening physical barriers between the two points.

They make use of the 2.4 GHz range since their connections to one another are wireless. It is possible for their connection to be disrupted by any other devices that operate on the same frequency band, such as a cordless home phone or a baby monitor.

It is in your best interest to move the sub around the room a few times before settling on the location that provides the optimal listening experience for you.
