Modern TVs are often equipped with flat enclosures that physically have no room for volumetric speakers, leading to compromises as audio accompaniment. The sound becomes flat, the depth of the low frequencies is lost, and the dialogue in films is sometimes difficult to disassemble without raising the volume. It is at this point that many users think about how to connect computer speakers to the TV to get a full surround sound without buying an expensive sound panel.
Fortunately, most active speakers developed for PCs have universal interfaces that make it easy to integrate into a home theater. Analog exitsDigital ports and wireless protocols offer ample opportunities for audio upgrades. In this article, we will take a detailed look at all the available connection methods, the nuances of the setting and the ways to solve typical sound problems.
Before you start buying cables or setting up equipment, you need to audit the available connectors on both devices. The type of available ports directly affects the quality of the transmitted signal and the complexity of the connection procedure. Do not ignore this stage, as the use of inappropriate adapters can lead to loss of quality or complete absence of sound.
Analysis of available interfaces and equipment preparation
The first step is always to visually inspect the back or side panel of your TV. Electronics manufacturers use different audio output standards, and understanding their purpose is critical. The most common option remains 3.5mm Mini-Jack connectorwhich is marked with a headphone icon or an inscription Audio Out. This is the easiest way to connect active acoustics, as it transmits an already amplified analog signal.
However, in today’s ultra-thin TVs, this port may be eliminated in favor of digital interfaces. In this case, your ally will be the optical output. Toslink Or a coaxial connector. They require an external digital-to-analog converter, as computer speakers usually cannot decode a digital stream directly. It is also important to note the availability of ports. HDMI ARCThese are the sound systems that allow sound to be transmitted in both directions, but require special support from the acoustic system.
⚠️ Warning: Before connecting any cables, be sure to turn off the TV and speakers from the outlet. Switching "hot" can lead to a voltage jump and failure of the output cascades of the amplifier or motherboard TV.
After determining the ports, prepare the necessary cables. If you use a wired connection, make sure the length of the cord is sufficient to comfortably place the speakers on the sides of the screen. For the wireless method, make sure that the module Bluetooth The TV is active and supports A2DP profile for high-quality stereo sound.
Connection via 3.5mm connector (Mini-Jack)
This is the most common and budget-friendly method that works with the vast majority of active speakers. Cable type "3.5 mm - 3.5 mm" often comes with acoustics, but if it is not available, you can buy such a wire in any electronics store. The signal is transmitted in analog form, so the quality will depend on the built-in digital-to-analog converter (DAC).
The connection process is as simple as possible: one end of the cable is inserted into the socket. Audio Out or Headphone on the TV, and the second - in the corresponding nest on the speakers or subwoofer. If your acoustic system has only an input RCA (tulips)You're gonna need an adapter. 3.5 mm to 2RCA. In this case, it is important to observe the color marking, although for a stereo signal, you can confuse channels only in the case of mono-recording.
After the physical connection, turn on the equipment. The TV can switch automatically to an external speaker, but most often manual tuning is required. Go to the audio settings menu and find the item “Output audio” or “Dynamics”. Select the “Audio System” or “External Speakers” option to turn off the TV’s built-in speakers and direct all stream to the connected speakers.
☑️ Checking the 3.5 mm connection
It is worth noting that when using a 3.5 mm connector, you may encounter a power limit. Built-in amplifiers for TVs are not always able to unlock the potential of powerful computer speakers, which can make sound appear quiet or distorted at high frequencies. In such cases subwoofer It can take the main load on low frequencies, improving the overall picture.
Use of HDMI and Optical Digital Interfaces
If your TV is devoid of analog output, digital interfaces come to the rescue. Optical port Toslink transmits a signal in the form of light pulses, which completely eliminates the appearance of electromagnetic tips and background. To connect, you’ll need a Toslink-Toslink cable and an external DAC (DAC) that converts the digital signal to an analog for your speakers.
A more advanced option is to use an interface. HDMI ARC (Audio Return Channel) This protocol allows the audio signal to be transmitted from the TV to the external speaker system via the same cable that transmits the image. However, for direct computer speakers, this method is rarely suitable, as they usually do not have an HDMI input. You will need a receiver or soundbar that supports HDMI ARC, which will already act as an intermediary.
| Type of connection | Sound quality | Difficulty setting up | Equipment required |
|---|---|---|---|
| 3.5 mm (Mini-Jack) | Standard. | Low. | Cable 3.5-3.5 |
| Optical (Toslink) | High. | Medium | DAC + Toslink Cable |
| HDMI ARC | Maximum. | Tall. | Receiver/Soundbar |
| Bluetooth | Depends on the codec. | Low. | Bluetooth module |
When setting up a digital output, it is important to choose the right sound format in the TV menu. For stereo systems, the choice of mode will be optimal PCM. If you choose. Dolby Digital or DTSAnd your acoustics can't decode these formats, and there's no sound at all, or there's a set of digital noises.
Why is the sound quieter when connected via DAC?
External digital-analog converters of the budget segment often have a lower output cascade power compared to analog output of the TV. The solution lies in increasing the volume on the DAC itself (if there is a regulator) or in using an amplifier.
Wireless connection via Bluetooth
Modern Smart TVs are almost completely equipped with a Bluetooth module, which allows you to get rid of unnecessary wires. This method is ideal for minimalist interiors where every cable is visible. To connect devices, put your computer speakers into pairing mode (usually with a long press of the Power button or a special button). Pairing).
On TV, go to the section. Settings → Sound → List of Bluetooth speakers (The path may vary depending on the brand, for example, Samsung, LG, Sony). Start a device search and select your acoustics from the list. After successful pairing, the system may suggest using the speakers as the default output device.
However, the wireless method has its nuances. The main problem may be the desynchronization of audio and video when the sound is behind the picture. This is called latency. To minimize this effect, make sure that the TV and speakers support modern codecs such as: aptX Low Latency or AAC.
⚠️ Note: When connected via Bluetooth, the battery of portable speakers will discharge much faster than when listening to music from your phone. Keep the charger on hand or use the powered speakers from the mains.
Another advantage of Bluetooth is the ability to connect multiple devices. You can easily switch from watching a movie on TV to listening to music from your smartphone without having to plug in the cables. However, for a home theater, a wired connection will always be preferred due to signal stability and lack of compression.
Customizing the sound and troubleshooting problems
After a physical connection, software customization is often required to achieve the best result. Go to the advanced sound settings of your TV. It’s worth turning off all “improvers” like virtual surround sound or automatic volume control if you want to hear a clean signal from the speakers. These features often introduce distortions that are noticeable on high-quality acoustics.
If the sound wheezes or is interrupted, check the volume level on the speakers themselves. It often happens that on the TV the volume is twisted to the maximum, and on the speakers - to the minimum. The optimal balance is achieved when the regulator on the speakers is set at 70-80%, and the main adjustment is made by the TV remote. This provides a better dynamic range.
If you hear a constant low-frequency hum, try to disconnect the cable TV antenna from the TV. Sometimes grounding through an antenna cable creates a so-called "ground loop" that generates a background.
If there is no sound, check the format of the audio stream. Some older speakers do not support multichannel formats. Forced to set the TV settings output sound in mode Stereo or PCM. Also make sure that your app settings (such as YouTube or Netflix) don’t select a separate audio language that your system may not support.
For owners of complex systems with a subwoofer, it is important to properly configure the crossover. If the bass is buzzing and drowning out voices, reduce the low frequencies on the subwoofer or in the settings of the TV equalizer. The correct frequency balance setting will make the sound clear and legible.
Comparison of methods and choosing the best solution
The choice of connection method depends on your priorities: quality, convenience or price. Wired connection through 3.5 mm remains the “gold standard” for most users due to its simplicity and lack of delays. It's most universalIt works 90% of the time without the need to buy additional equipment.
Digital methods (Optical, HDMI) are preferred for audiophiles who use high-quality external DACs and amplifiers. They provide lossless signal transmission, but require more serious investment and knowledge. Wireless technology is good for temporary solutions or when aesthetics are more important than absolute sound quality.
For most users, a 3.5mm wired connection is the best choice, as it balances sound quality, stability and ease of implementation.
Remember that even the most expensive speakers will not sound right if the source of the signal is configured incorrectly. Take time to fine-tune the equaliser and volume levels to turn watching movies into a true cinematic experience.
FAQ: Frequently Asked Questions
Can I connect speakers via the TV’s USB port?
In most cases, you can not directly connect active computer speakers via USB, since this port is designed to power or read files from flash drives. However, if you have a USB audio card (external DAC), then the connection is possible through it.
Why did the sound on the TV disappear when you connected the speakers?
Most likely, the TV automatically switched the output of sound to the external port, but the speakers are turned off or turned down their volume. Check the audio settings in the TV menu and make sure the right output type is selected (e.g., Audio System instead of TV Speaker).
How to improve the sound quality if it seems quiet?
Try to increase the volume directly on the body of the speakers or subwoofer. Also in the settings of the TV you can find the function “Night mode” or “voice amplification”, which raises the level of the average frequencies. Make sure the cable is in good working order and sits tightly in the nest.
Will the old 2.0 speakers be suitable for the new Smart TV?
Yeah, they do. The 2.0 standard computer acoustics (two speakers) work well with modern TVs, especially if connected via 3.5mm analog output. You will get a much better sound than the built-in TV speakers.
