How to connect speakers to your LG TV

Multimedia center

It is also possible to improve the sound transmission of television programs due to the multimedia centers available in the house. Powered speakers of these systems have built-in power amplifiers, so they can deliver an improved dynamic range: you can get better sound with less power. Acoustic design will be legible and clear.

connect, speakers

Computer speakers are also, as a rule, active audio devices. They receive power from the electrical network, so there is no need to pull additional wires.

Simple columns

If you replace the small internal TV speakers with a pair of external or shelf-built speakers, you will notice how much the quality of your TV sound system will change. It is not necessary that the speakers for the TV be very large, but it is desirable that the speakers have their own amplifier.

The design of standard speakers can be different: round, square, oval, flattened. They are also made from different materials: plastic, MDF, fiberboard or chipboard. If the speakers have a built-in amplifier, then they will have an additional power cord. Active speakers will be able to significantly improve the comfort when watching TV programs, because they have their own sound amplifier.

If you decide to connect passive speakers to your TV, then you need to pay attention to the power of the speakers. This parameter should in no case be lower than that of the TV, otherwise the speakers will wheeze at high volume and quickly fail. It is also important to observe the polarity when connecting (if there are no signs “” and “-“, then the polarity can be determined using a conventional battery).

The easiest way to improve the sound of your TV is to connect stereo speakers through the RCA outputs. Analogue RCA connection outputs send two channel stereo (content dependent) from the TV to an external audio system, which even passive speakers can receive.

Home theater connection

The peculiarity of connecting a home theater is that in the set of multimedia centers there are no wires for connecting additional devices, so you will have to buy them yourself.

Look at the back of the center and find the video input jacks. Use the same method to determine the type of video output on your TV. Now you need to connect the two devices to each other, but do not forget to disconnect them from the electrical network before connecting.

Most often, the connection of a TV to multimedia equipment is carried out either through line connectors or SCART. Once connected, the speaker is set to “AUX” mode. If you did everything correctly, then the sound from the TV should come from the speakers of the media center.

If you made a connection and noticed that the sound is broadcast poorly or there is extraneous noise, then the reason may be the wrong speaker volume parameter. Adjust the speaker volume by changing the settings on the TV and directly at the very center.

However, there are many new TVs that do not have analog outputs (RCA or SCART) and instead have an HDMI port. For example, TVs TM Samsung without audio are very popular these days. This means the audio output is built into the HDMI card on the device.

Of course, this can intimidate the user if their stereo receiver only has an RCA audio connection. But do not rush to worry, there is an option for such a situation.

HighDenition Multimedia Interface is an audio / video interface that is used to transfer audio and visual data. This is the flat port you see on TVs, audio systems, and other devices. If both devices have HDMI ports, then there will be no connection problems: all you need to do is connect the TV to the audio system using an HDMI cable.

However, if your TV has HDMI and your audio system does not have one, you will need a dedicated switch box. A typical HDMI 4 × 1 switcher has 3 to 4 different options for separate audio outputs to connect to your sound system:

  • Digital coaxial;
  • Digital optical;
  • Analog RCA port (red and white jack).

You just have to choose the port that your audio system supports. With this switch, you can connect any receiver, external speakers, home theater or surround sound system. This solution will allow you to truly enjoy music or a movie, and especially gamers will like it.

The process of connecting speakers to a TV

To connect your stereo speakers to your TV, follow these steps in this order:

  • Place the receiver or amplifier as close as possible to the TV, while remaining within the reach of other devices (cable or satellite box, DVD player, etc.);
  • Ideally, the TV should be located 120-180 cm from the amplifier, otherwise a longer connecting cable will be required;
  • Make sure all equipment is turned off before connecting;
  • Find analog or digital audio output on the TV (AUDIO OUT), it can be two RCA sockets or one 3.5 mm mini-jack, for digital audio transmission there will be an optical output or HDMI OUT port;
  • Find a free audio input (AUDIO IN) on your stereo receiver (most likely, the stereo or home theater input will be an RCA jack or an HDMI input port);
  • Using a cable with appropriate plugs at each end, connect the TV’s audio output to the receiver’s audio input;
  • When all cables are connected, turn on the stereo amplifier and TV. But before checking the result, make sure the volume on the receiver is at a low level. The TV sound should now be coming from the speakers.

All audio in and audio out connectors are always signed, so it’s easy to navigate through them. Below you can see a diagram of the main connectors:

Let’s take a look at how to connect speakers to a TV using an RCA connection.

Look at the back of your TV, if there are red and white RCA jacks labeled “audio out”, then you can use a regular left and right stereo audio cable (cinch) to connect. We connect one end of the cable to the TV according to the corresponding colors of the connectors, and the other to the speaker connector, where there is an inscription “Audio input”. If the device has several inputs, it is better to connect to the one marked as “TV-IN”.

Please note that the “jack” standard does not always mean that the signal will be received in “stereo” format: if the plug has 2 pins, then this is mono sound, and if there are 3 partitions, then this is a stereo transmission.

It’s important to note that RCA or 3.5mm analog connections are no longer available on many newer TVs. This means that if you are buying a new TV and your soundbar or audio system only has analog audio inputs, you need to make sure that the TV you are planning to purchase does indeed have an analog audio output option. Otherwise, you may have to upgrade to a new soundbar or audio system that provides digital optical audio and / or HDMI-ARC connectivity options.

Depending on the speaker system and TV model, there may be the following connection options:

  • The use of fiber optic cable is considered optimal. It does not respond to electromagnetic radiation, so the sound is delivered without the slightest interference or distortion. Connect the “optical out” cable on your TV set-top box to the “optical in” port on your cinema receiver, and you can enjoy deep and high-quality sound while watching any program;
  • It is possible that your model of equipment has coaxial jacks, this is also an excellent option for the pure transmission of multichannel sound without the procedure for converting to an analog signal. The audio output connector on the TV will be called S / PDIF (Sony / Philips Digital Interface), or “out coaxial”, and on the cinema receiver “coaxial in”.

Speaker selection tips

How to choose speakers for your TV and choose the best one? It all depends on your budget and your individual sound quality requirements. For some it will be quite acceptable if their speaker system costs like a car, but for someone one pair of inexpensive wooden speakers would be an excellent option.

If you’re a passive music listener and just want to make your TV sound more clear, you don’t necessarily need huge speakers or a full 7.1 surround sound system. You can opt for conventional shelf or wall-mounted speakers of any worthy brand (SVEN, Yamaha, VVK, Philips). Want more bass? A small subwoofer will help provide additional low-frequency range.

If you are an active music listener or just want a deeper immersion in the plot on the screen, then you should pay attention to the floorstanding speakers. Even a small floor-standing loudspeaker with several satellites can reproduce truly full, very pleasing sound without taking up a lot of room space.

Installing a soundbar is also a great option to improve TV sound. Many models of these speakers come with a built-in subwoofer, which is very convenient for a perfect integrated design.

Soundbars can significantly improve the sound of TV speakers, but they cannot compete with professional home theater speakers, in which the sound system is built around a high quality AV receiver and a very powerful amplifier. From such speakers, the sound comes not only perfectly clean and balanced, but also truly spacious and realistic.

An important part of the TV speaker selection process is considering the space in which the speakers will operate. Closed small rooms are not very good conditions for large floor-standing speakers: firstly, they will take up a lot of space, and secondly, they will “load” the room with bass, which can lead to a muddy sound. But large and spacious rooms will make the sound of a small speaker small, not too noticeable and localized.

A very popular option is the choice of wireless speakers. Such elements are connected to the music center via Bluetooth. There are no wires behind them, so they can be installed even in the uppermost corners of the room.

But in addition to aesthetic criteria, it is important to pay attention to two main technical characteristics of acoustic devices. sensitivity and power.

READ  Screen share LG how to connect phone

The first parameter is measured in decibels and directly affects the level of the output loudness: the higher the sensitivity value, the louder the system will be able to reproduce the sound.

Speaker power is another metric that affects speaker volume. It is defined in three different parameters:

  • Nominal;
  • Maximum;
  • Peak.

You need to focus on the indicators of the nominal power, however, here it cannot be argued that the higher the power value, the better the speaker will sound. It would be wrong to say that a 150-watt equipment will produce better and stronger sound than a 50-watt speaker. The acoustics power characteristic speaks only of the mechanical reliability of the speakers.

When choosing speakers, you need to focus on the size of the room in which the acoustic equipment will be installed: the larger the area, the more powerful it is to buy the speakers. For a room with an area of ​​20 square meters, a 50 W speaker will be sufficient, and if you are equipping a living room of 30 m2, then it is better to choose from 100-watt models.

Options for acoustics to the TV and how to connect it

Lately, the picture quality standards for watching TV have risen sharply, and today all modern models of LCD, plasma and OLED TVs are able to recreate an excellent, crystal clear picture, but they are not able to provide adequate sound.

Their tiny built-in speakers cannot clearly reproduce dialogues, much less convincingly immerse us in the atmosphere of realistic explosions, car accidents and other disturbances that we see in the plots of our favorite films. If you want to really feel surrounded by a movie soundtrack, hear powerful immersive sound, or simply get a clearer broadcast, then it’s better to use additional speakers for your TV.

Our detailed guide will clearly outline all of the options for getting the best sound for your TV.

Home theater

It makes sense to combine the stunning visual clarity of your HDTV with the same stunning sound quality. And what equipment will cope with this task best of all, if not the “Home Theater” speaker system?

These are not just high-level speakers, this is a whole complex of sound-reproducing devices, created for optimal conditions for viewing video material at home. This technique completely immerses you in the events on the screen due to the well-thought-out sound distribution.

A home theater speaker system can have different designs, depending on the size of the area for which it is designed. There are systems 2.1, 3.1, 5.1, 7.1, etc. It may contain the following elements:

  • Front, rear, center speakers (floor, wall, mounted);
  • Subwoofer. for reproducing low frequency sound;
  • Satellites. auxiliary devices operating in a limited frequency spectrum;
  • Soundbar. a mono speaker with several internal speakers.

The more elements the system has, the higher the broadcast quality. And so that the sound transmission is at a high level, they use multi-channel communication.

Using the LG TV Plus program

LG has an app that runs on Android and iOS that lets you control, customize your TV just the way you want it. To enable:

  • Install the LG TV Plus app from the App Store or Play Market.

Features of the

A Bluetooth module at a short distance allows you to quickly transfer information between connected devices. You can connect your smartphone to TV and transfer sound, media files and other file formats to play them on the screen.

Before setting up, it is recommended to check the characteristics of the connected TV and find out if it has a Bluetooth module. If not, you need to connect an external adapter.

An external Bluetooth adapter can be of two types: with a USB connection and a mini-jack. After finding or installing it on your TV, proceed to set up.


How to turn on Bluetooth on LG TV? LG Smart TV uses the webOS operating system. Works webOS 1.0 and 2.0 only with branded headphones. Starting from version 3 (from 16 year old models), other sound players can also be connected.

  • Put your headset in pairing mode.
  • Press the “Menu” or “Setting” button on the remote control to enter the settings.
  • In the menu that appears, select Sound.
  • Move the checkmark to “LG Sound Sync / Bluetooth”.

  • Through the manager, open the item where there is Bluetooth. This can be the “Sound” section or other parameters.
  • Activate the module.
  • Put the headphones into pairing mode.
  • Start looking for a wireless device and pair with it.

Putting the headphones into pairing mode

Typically, headphone and headset control is performed with one button. It can be located on one of the headphones. Just pinch and hold it for 7-10 seconds.

The notification about the change of the mode can be sound or by means of indication. Typically, the tracking mode is a rapidly blinking light in one or more colors. You have on average a minute to pair with your TV.

Does LG TV have Bluetooth and how to turn it on?

There are many smart devices on sale. LG is no exception and produces TVs with many additional features. For example, it equips a TV Bluetooth module that allows you to connect a wireless headset or speakers to output sound from a large screen. Even if your LG TV doesn’t have built-in Bluetooth, you’ll learn how to set it up.

The inclusion and subsequent pairing of wireless, non-proprietary devices is possible in new LG firmware, starting with webOS 3.0. You can turn on Bluetooth on TV through the manager in the sound settings or in the LG TV Plus app.

Home theater

Home theater provides high quality audio transmission. It is the most optimal stereo system. For the highest quality sound, a 5.1 sound system is used, consisting of speakers and one subwoofer. The system has an amplifier with a professional receiver, which makes the sound of the speakers clear and spacious.

Samsung TVs have digital HDMI connectivity for superior sound output. Before connecting the home theater, you should turn off the TV to avoid short circuit.

IMPORTANT! Experts recommend connecting strictly following all the points described in the instructions.

Simple columns

It is possible to directly connect simple computer speakers to any TV device equipped with a TRS 3.5 mm jack.

They also require additional power. sockets. Before connecting speakers to an LG or Samsung TV, you need to make sure that the device has the appropriate outputs on the panel. A sound amplifier and volume control system will help you achieve decent sound.

Types of inputs and connectors

For sound output, all TVs are equipped with special inputs and connectors that allow you to connect third-party speakers. Before connecting a speaker system, you need to determine which outputs on the TV are provided.

Special purpose connectors (SCART, RCA). They connect devices without a built-in amplifier.

Digital connector (HDMI ARC). The input allows you to connect modern speaker systems to your TV, as well as amplified speakers and home theater systems with the ability to reproduce truly high-quality sound. Not all television devices are equipped with such an input, but only the newest and most expensive ones.

With HDMI input, the user can enjoy great sound through the transmission of a high definition digital signal. Not to be confused with normal HDMI input.

Headset jack and line-in. Used if the TV has no dedicated inputs. Connection is carried out by adapters. tulips.
To determine how easy it is to connect the amplifier to a TV, you need to inspect the rear panel of the device for the necessary connectors.


Many owners of computer monoblocks ask themselves the question: how to connect the candy bar to the TV? This process is simple, just connect your computer to TV via HDMI or USB cable. In the settings you need to select the input source.

It’s a little more difficult to set up the sound so that it is output from the TV speakers. To do this, go to the sound settings on your computer and select the default HDMI output. If nothing has changed, in the “Supported formats” tab you should adjust the sound frequency, which should be equal to 48 kHz.

Composite stereo system

The equipment has an almost perfect sound quality. Consists of the following elements: powerful speakers with a built-in amplifier, passive acoustics, and a subwoofer that decomposes sound into separate channels. Taken together, the composite stereo system will provide comfortable listening not only to musical compositions, but also surround realistic sound when watching a movie.

The stereo system is connected to a Samsung TV or other brands using the tulip connector. RCA or TRS adapters are also used. The sound from the TV is output directly to the speakers of the active group, so you need to use the recommended wires and cables.

How to connect speakers to a TV for sound output

Many TVs are not equipped with the highest quality speaker system. When watching movies or TV broadcasts, there is little sound from the built-in speakers. To make it more spacious and loud, you can connect any other sound amplifier to it. There are several options for how to output the sound from the TV to the speakers.

Types of acoustics

Speakers for Samsung TV and other TV models are divided into two main groups in terms of technical characteristics: active and passive. The first are equipped with a built-in amplifier as standard and are powered directly from the mains. They do not require the help of additional devices. Typically, this type of acoustics is most often found in computer speakers.

Connection takes place through a standard Mini Jack connector. Powered TV speakers are connected to the device using round 3.5 mm inputs. If the TV is not equipped with such a connector, then a special tulip adapter is used.

Passive acoustics, or subwoofers, do not have a sound amplifier, which changes the connection algorithm. It must first be connected to an amplifying device, then into one of the connectors on the TV panel.

IMPORTANT! If the polarity is not respected, the sound quality will be impaired.

Wireless speakers

Modern Smart-TVs have a built-in Bluetooth module that allows you to pair your TV with other devices. It is not difficult to connect wireless speakers to a TV device, since the system has an intuitive principle that may differ slightly on different models. This method is convenient because the speakers can be remotely connected to a Samsung TV without unnecessary wires.

To connect wireless speakers, you need to do the following:

  • In the TV settings menu, find the Bluetooth item and turn it on.
  • The headset must be switched on for Smart-TV to find it.
  • Then select the desired device for pairing.

Wireless speakers for TV are compatible not only with Samsung models, but also LG, Sony, Phillips and other manufacturers. Read the instructions that come with Smart TVs.

How to connect speakers to your LG TV

Modern LG TVs boast high-quality sound. Nevertheless, many equipment owners want to further improve the audio system by connecting speakers to the TV. This allows you to enjoy the highest quality surround sound.

Before you start connecting speakers, you need to clarify what audio jacks your LG TV model is equipped with. The most common are digital HDMI, line-in (MiniJack) or dedicated speaker SCART or RCA.

LG TV models with Smart-TV have the ability to connect wireless speakers via Bluetooth.

HDMI. Found in most modern TVs and home theaters. Allows you to transfer information without loss of quality.

If you are going to connect a powerful audio center with built-in amplifiers to your TV, it is recommended to use HDMI connectors.

MiniJack, SCART (hairbrush) and RCA (tulip) are not designed for high-power audio systems. When using these connectors, you need to be especially careful, because if you connect speakers with a more permissible power to the TV, there is a risk of damage or even damage to the equipment.

The second thing to look out for is the speakers themselves. Acoustic systems are active and passive, and the connection method depends on their type.

Active speaker system assumes the presence of a built-in amplifier and is connected to the mains for power supply. In the overwhelming majority of cases, such speakers are connected to the TV using 3.5 mm inputs, designated MiniJack or TRS. In the event that your LG TV does not provide such connectors, you can solve the problems by purchasing an additional adapter “MiniJack / RCA”.

Passive speaker system is not equipped with an amplifier, it must be purchased separately and the speakers must be connected first to it, and only then through the amplifier to the TV. In this case, there is a possibility that the sound quality will not be optimal.

Here’s what to look for when choosing an amplifier:

  • Its power should not be more than a third higher than the power of the speakers. (Carefully read the User’s Guide for the speakers, this information is sure to be there).
  • The impedance of the amplifier and speakers must be equal.
  • The wire with which the amplifier will be connected to the TV is very important. Experts recommend not to use a cord with a cross section of less than 2 mm.

How to connect speakers to a TV using wires: step by step instructions

  • Having decided on the type of connector, connect the HDMI, RCA or MiniJack cable to the corresponding jack on the back of the TV.
  • If you are connecting computer speakers to your TV, use your TV as a power source. To do this, plug them into any free USB port on the rear panel.
  • Adjust the sound settings on your TV.

How to connect wireless speakers to your TV: step by step instructions

  • Turn on the TV using the remote.
  • In the “Menu” find the Bluetooth section and make sure that this option is active.
  • In the list of available devices, find the Bluetooth speaker you want to connect.
  • Sync your devices.

After you have successfully connected the speakers to your LG TV, you need to complete the process by adjusting the sound settings on the TV itself.

  • In the menu, select the item “Home” (Icon “Home”).
  • Go to the section “Settings” (Icon “Gear”).
  • In the upper right corner, find the icon with three vertical dots, and in it the “Sound” section.
  • In the subsection “Audio Out” select “Audio Out (Optical / HDMI ARC)”.
  • Activate SIMPLINK mode.

If you are using a speaker that supports LG Sound Sync:

  • In the menu, select the item “Home” (Icon “Home”).
  • Go to the section “Settings” (Icon “Gear”).
  • In the upper right corner, find the icon with three vertical dots, and in it the “Sound” section.
  • In the subsection “Audio Out” select “LG Sound Sync (Optics)”.

If you are connecting an audio system that supports LG Sound Sync using Bluetooth, select “LG Sound Sync (Wireless)” in the settings.

Active type systems

Such acoustics have a built-in amplifier. It does not need any additional devices or connections, because it is powered directly from the electrical network. Sometimes such systems are also found in speakers from a computer.

Connector types

Before connecting your speakers, you need to figure out what audio jacks your TV has. Most modern models have one of three types of electrical connectors.

  • Special acoustic connectors. These include inputs such as SCART or RCA. Connecting through this type of connection is similar to connecting computer speakers over USB. It is usually used for systems without a built-in amplifier. But be sure to make sure that the power of your acoustics does not exceed the permissible level, otherwise you can burn not only the connector, but also the equipment.
  • Line-in or MiniJack. Such connectors usually have a separate headset output. Just like the first option, they are not suitable for high-power systems with built-in amplifiers. It is likely that you will need a special tulip adapter to connect through this port.
  • Digital HDMI connector. Such outputs are equipped with ultra-modern models of such large companies as LG or Samsung. Only powerful music centers are connected through it. Usually such connectors can be found in home theaters, where sound quality is as important as picture quality.

How do you determine which connector is on your TV? Take a look at its back panel. The SCART connector looks like an oblong line with two rows of holes.

CRA. three round connectors for plugs, usually colored yellow, white and red. MiniJack inputs are somewhat similar to CRAs. They are also round, but noticeably smaller and painted in different colors. The standard is green, black and pink. The HDMI connector is about 1.7 cm long and 0.5 cm high. In its recess there is a small plate with contacts, with the help of which information is transmitted.

Which speakers are right?

Large home loudspeakers are active and passive. Their connection and features are slightly different.

How to connect speakers to your LG TV?

Modern TVs have achieved incredible heights in the quality of the broadcast image, in ergonomics and space saving. However, in all these widescreen innovations, there is absolutely nowhere to install high-quality speakers that would provide good sound. to match the image. Therefore, sooner or later, any user thinks about connecting an external speaker system.

Passive acoustics

This type of system cannot be connected directly to the TV. You will need to purchase an additional amplifier for the speakers to work. And from the amplifier already pull the wire to the TV. When connecting them, you will have to take into account a number of features.

  • When choosing an amplifier, pay attention to the fact that its power does not exceed the power of the speakers themselves by more than 30%.
  • The thicker the wire between the system and the TV, the more reliable the connections will be. It is not recommended to take wires thinner than 0.2 cm in cross-section.
  • Amplifier and speaker impedances must be equal.
  • Pay attention to the polarity. Connect the left speaker to the left channel, and the right speaker to the right. If you do otherwise, it can have an extremely negative effect on the quality of sound perception.

Of course, you can connect any speakers to modern TVs, whether they are from a computer, from a music center or professional acoustics.

Many models with Smart TVs now even have Bluetooth, thanks to which you can use not only wired speakers, but also portable ones, for example JBL.

Pairing with wireless speakers is no longer a problem for modern LG smart TVs. Connecting them via Bluetooth is as simple as possible:

  • turn on the TV and find the “Bluetooth” tab in the main menu;
  • now turn on the column and, if necessary, activate the device search function;
  • in the list of available devices on the TV screen, find your headset and select it.

Now it remains only to wait a little while the pairing is established, and you can use the system.

Connecting speakers with wires differs depending on the type of connection. Plug the Cinch, HDMI or MiniJack into the corresponding port on the back of your TV, and plug in the plug and the system is ready to use. If you take small computer speakers, the power of which is relatively low, then they can use the USB connector as a power source. Fortunately, TVs usually have 2 or 3 of these.

Connecting speakers to your LG TV is easy, whatever they are. The main thing you need to know for this is the type of their connection and the type of TV connector. You can even use speakers from the music center, but do not forget that, most likely, they are of the passive type and require an additional amplifier.

How to connect speakers and headphones to a TV via HDMI ARC, see below.

Line Inputs

When the TV model for connecting speakers is equipped with line outputs, you can use the usual contacts: and This option is suitable for computer speakers or from a home theater.

It is required to carefully examine the back of the device, if there are two holes with terminals (red and black) on it. these are the line outputs.

All you need to do is connect the wires according to the colors:

The sound will appear immediately if everything is connected correctly.

Via bluetooth

Often, modern TV models are equipped with Bluetooth. With this function, you can make a wireless connection between the devices.

You can connect acoustics via Bluetooth if the speakers also have such an option. In the TV menu, you need to find this function and activate the device search. Then select the desired item, and the sound will go to the speaker.

How to properly connect speakers with a subwoofer to your LG TV

Modern technology, regardless of direction, is distinguished by expanded functionality. As practice shows, HD technologies are produced with primitive speakers, as a result of which even owners of expensive TV models cannot enjoy the sound effects as much as possible.

This sound is enough for watching entertainment programs, movies and news. When it comes to surround sound, you need to additionally connect speakers to the TV. As a result, you can get a really high-quality result.

Next, let’s take a look at how to connect speakers to your LG TV. There are several options, and it is important to choose the best TV device for your model.

Connection methods

There are several ways to connect speakers to a TV device. Each option is suitable for a specific type of speaker system. The method varies depending on the model and TV. Next, we will consider the possible options for connecting acoustics. Note that for maximum sound effect, you have to figure out the acoustics settings. This type of equipment offers a fairly wide functionality to users.

Types of inputs and connectors on LG TVs

Initially, you need to understand what outputs are present on the TV. Only then can the acoustics be connected.

In the production of modern TVs, types of audio and TV connectors are used, due to which you can connect different acoustics for watching television:

  • tulip (RCA);
  • line-out;
  • headset or headphone jack.
  • HDMI ARC port.

The first option is used to connect active speakers that have a built-in amplifier. Options.3 are used if the device does not have special connectors. That is, the speakers are connected to the built-in amplifier in the TV.

HDMI ARC is ideal for newer technology. For example, a home cinema audio system that delivers high quality sound.

RCA connector

Tulips are considered the most popular TV connectors, regardless of the manufacturer. South Korean brand LG is no exception. Using this port, you can also connect speakers. There are several options.

In the absence of an RCA output on the speaker, most likely there is a 3.5 mm jack. Then you need a cable: RCA-TRS 3.5 mm. You can find such a cord without any problems.

Now for the question of how to connect a subwoofer to an LG TV. It should be noted here that there are several types of subwoofers:

  • Active. The set includes a built-in amplifier with a power that allows you to remove the output load in the case of playing low-frequency sounds.
  • Passive. In this case, the emitter does not have a personal amplifier, which affects the load of the output stereo channels. Therefore, the sound volume is often reduced and the quality deteriorates. There is no panel with settings, which significantly complicates the process of placing the subwoofer.

The active buffer is connected as follows:

  • A place is selected for the device.
  • Tulips are connected in accordance with the connectors on the TV case.
  • Setting up via the TV menu.

LG releases TV models with built-in automatic settings for syncing with different devices.

Connecting such a device has a convenient and intuitive interface. Even those who have not previously dealt with connecting a subwoofer should quickly figure out this process.

Anyone who purchased a passive device can synchronize using a home theater or receiver. The characteristic features of this option are: labor intensity and poor sound quality. The reason for the low quality is that it is not possible to properly position the subwoofer near the TV. Observe polarity when connecting for high quality performance.

HDMI cable

Considering the issue of high-quality sound and connecting acoustics, you need to consider the method with the HDMI ARC connector.

LG Smart TV. Connecting to Home Theater System

HDMI cable for TV is considered the most ideal option, which is able to really preserve sound quality.
This method requires the TV to have a dedicated HDMI ARC output.

This connection method is suitable for complex equipment, modern home cinemas, professional receivers. The result is high quality sound with preserved volume and effects. This is only on condition that the speakers of the system will meet the specified requirements.

Of course, many do not connect speakers to TV if they are satisfied with the sound. If you like surround sound when watching thrillers, action movies, then choose the most suitable option for yourself.

Optical cable for TV or home theater

Modern technologies make it possible to use optical cables not only for industry, quite often they are used for high-speed and high-quality transmission of various kinds of signals. They also found application for connecting TVs and home theaters.

  • Internet connection;
  • Sound and image transmission.

Using optical cables, you can connect 5.1 sound systems to the TV, as well as the Internet. An important condition when connecting various systems is the correct selection of the cable, which will allow for a reliable connection and long-term operation.

Optical cable must be chosen wisely

The TOSLINK cable is common for connecting audio systems, as it supports many formats. But to transfer video to TV screens, cables marked (EIAJ / JEITA RC-5720) are used. TOSLINK cables are used by well-known manufacturers such as LG (LG), Samsung (Samsung) and Genius.

However, they have some disadvantages. These cables may transmit noise, jitter or disconnect. These models have high resistance.

It is important to know! For transmission of the highest quality picture and sound, it is recommended to use cables no longer than 4 meters.

But the main difference from other types, fiber optic cables have a very high bandwidth. And their correct application will allow you to achieve high results.

How to connect sound and TV

As you can see, connecting various audio systems and home theaters, as well as their individual parts, does not require specialized knowledge and skills. You can easily cope with this on your own. And do not forget that when buying a home theater, detailed instructions are always attached.

How to connect a home theater to a TV: instructions

The work of a home theater is that the processed signal from the source is fed through the receiver to the speakers and to the TV screen. There are several connection methods for transmitting images through a home theater.

  • HDMI cable;
  • RGB cable;
  • Composite connector.

In order to display a high quality picture on the TV screen, use the method using an HDMI cable, which usually comes with a set of cables for connecting a home theater. It is simply not possible to confuse the correct connection, which makes the task easier. The plugs on the cable resemble the (USB) charging plugs, only slightly larger. To connect on the receiver, find the inscription (HDMI OUT), and on the TV (HDMI IN).

Connecting your home theater to your TV

A feature of the HDMI cable is that it is capable of transmitting not only picture, but also sound.

It may be that your TV is missing a jack or is already occupied by another cable. In this case, you can use an RGB cable. Unlike the previous one, this cable is only capable of transmitting an image. This cable consists of three wires connected together with lugs in three colors (red, green, blue). Connects to connectors labeled (Component Video Out) and (Component In), according to connector colors.

Also, it is possible to connect using a composite cable. Connection is made via composite connectors marked (Composite Video Out) and (Composite In). Unlike other connection methods, this one displays a picture of not very high quality.

How to connect an optical cable?

Optical cables are the most attractive means of transferring large amounts of information. However, do not forget that pulling fiber to one computer is almost never used practice.

Details on connecting optical cables can be found at This publication will present general techniques.

Why optical cables have become so common?

The fact is that the amount of information is increasing exponentially. The exponent of the need to transfer increasing volumes of information forces specialized organizations to use reliable data transmission channels.

Electrically transmitting such data arrays is not possible.

In addition, the transmission would be similarly affected by electromagnetic interference. The percentage of information lost in the event of transmission over long distances is unacceptable.

Among the disadvantages of optical fiber, it is observed that it cannot be folded at an acute angle due to the risk of breaking off.

How do I connect an optical cable? | Want to know everything!

A digital optical audio cable is required when transferring compressed digital audio from a computer (CD player) to a speaker system or receiver. If necessary, you can connect it yourself.

Oksnm recommends using an optical cable in cases of short distances and the danger of radio frequency interference.

This cable does not need to use electricity when transmitting a digital signal, does not generate interference, almost does not distort the sound on the computer. Install all drivers, application software bundled with the sound or motherboard, in strict accordance with the instructions. These actions will enable the computer and the external audio signal receiver to correctly determine the optical connection for the period of connection.

This procedure does not require household audio devices specifically designed to operate using an optical cable. These include a digital home theater equipped with a built-in electronic circuit that can independently determine the signal connection period using an optical audio cable.

Next, you should connect one of the ends of the audio cable to the source port on an external sound card (computer) using the S / PDIF connector. This is a rectangular port that is compatible with an audio cable connector that is tamper-proof.

The other end of the cable connects to the port on the digital audio receiver. Most often on consumer audio devices, they are designated TOSLINK, Optical Digital, S / PDIF. Disconnect other audio cables and connecting devices as the audio system may continue to use them by default. You can use the input selector on the amplifier.

Methods: how to connect a laptop or computer to a home theater

Nowadays, more and more people use TV as “furniture”. With the development of Internet technologies, it became possible to listen to music and watch movies on a computer. And to enjoy high quality picture and sound, you can connect your computer to your home theater.

  • Using cables;
  • Via an external sound card.

To provide surround sound transmission from your laptop to your home theater, you need an HDMI cable. It makes it possible to transmit both picture and sound. To do this, you need to connect the cable connector to the GDMI output on the laptop, and the second directly to the cinema (receiver). After that, the sound and picture should be played through the cinema.

If this does not happen, you must configure the playback device on the computer itself. To do this, go to the control panel, select the Sound tab. Next, the playback tab opens. Select a device with HDMI support, right-click on it and select “use default device”. Then we click on “setting” and select the appropriate system for playback (5.1 or 7.1). The setup is complete and the sound should be dropped from the laptop speakers.

If the connection is made via a computer video card with a DVI. HDMI adapter, then the sound will need to be fed to the receiver manually. To do this, you need to use an SPDIF cable, connect the motherboard or sound adapter with a video card.

It is important to know! The integrity of the cable directly depends on the correct connection. The cords must be connected according to the marking.

If your laptop does not have an HDMI connector, you can use a simple solution in the form of an external sound card. To connect it does not require special skills and knowledge, as well as for some types of special installation programs. In these devices, it is possible to connect not only receivers, but also microphones with headphones.

You can also use your phone to control the system.
