Today's TVs are getting thinner, which inevitably affects the quality of the built-in sound. Many users are faced with a situation where the picture is pleasing with detail, and the audio is much to be desired. At this point, external acoustics come to the rescue, and the soundbar Xiaomi Redmi TV Soundbar is a great choice for the black how to connect to the TV - this is the question most often arises for new owners of the device.
The device offers an impressive balance between price and sound quality, providing a powerful bass and clean high frequencies. However, to unlock the full potential of the 2.1 subwoofer system, you need to properly perform the initial setup and choose the optimal connection method.
In this article, we will take a look at all the interfaces available, from wired digital connections to wireless protocols, how to avoid audio delays while watching videos and how to set up the soundbar to automatically turn on with the screen.
Compilation and preparation of equipment for installation
Before switching cables, you need to make sure that all the components are present. In the box with Xiaomi Redmi TV Soundbar usually contains the sound bar itself, subwoofer, remote control, power cables and optical cable. It is important to check the integrity of the connectors and the absence of physical damage to the body, as transportation may have affected the condition of the device.
Special attention should be paid to the choice of place to install. The low frequency subwoofer is best placed on the floor near the wall, but not close to it, to avoid buzzing. The sound bar itself should stand stable in front of the TV or be fixed to the wall with a mounting kit, if this is provided by your model.
- 🔌 Check the availability of all cables in the package, including optical and AUX.
- 🔋 Make sure that the remote controls have fresh batteries for initial setup.
- 📺 Check the back of the TV for ports. HDMI ARC, Optical and USB.
Do not ignore the instructions attached to the device, especially in terms of power requirements. The soundbar power unit should be connected directly to the socket, the use of extension cords with poor contact can cause interference or unstable system operation, it is also recommended to free up space around the TV in advance for convenient access to the connectors.
⚠️ Warning: Before connecting any cables, be sure to disconnect the TV and soundbar from the power grid. Inserting plugs into a working device can short-circuit and cause ports to fail.
Choosing the optimal connection interface
The success of integrating acoustics into your home system depends on the method of connection you choose. Xiaomi Redmi TV Soundbar supports several signal transmission standards, each with its own advantages and limitations. Understanding the difference between the two will help you get the highest possible sound quality for your TV model.
The most advanced option is the HDMI ARC (Audio Return Channel) port, which allows you to transmit high-resolution multichannel sound and, most importantly, allows you to control the soundbar volume from the TV remote, and if your TV supports this feature, you should choose it, because it will eliminate the need to use two different remotes.
If you don't have an HDMI ARC or connect to older TVs, you should consider Optical/Toslink, which provides lossless digital signal transmission, supporting formats like Dolby Digital, but does not allow you to control the volume from the TV remote to the fullest. Analog AUX or Bluetooth should only be used as backup options when digital ports are busy or absent.
| Interface. | Sound quality | Control from the remote | Support for formats |
|---|---|---|---|
| HDMI ARC | Maximum. | Complete. | Dolby, DTS, PCM |
| Optical | High. | Partial/No | Dolby Digital, PCM |
| Bluetooth | Average. | No. | SBC, AAC |
| AUX (3.5mm) | Basic | No. | Analog stereo |
When choosing a cable, remember that length matters. For optical cables, it is not recommended to exceed 5 meters in length without using signal amplifiers, as light can fade. HDMI cables must comply with the High Speed standard to ensure stable data transfer without artifacts.
Connecting via HDMI ARC and setting up CEC
Using an HDMI ARC connector is the gold standard for home theaters. To have the Xiaomi Redmi TV Soundbar black soundbar plugged into your TV in this way, find an ARC-marked port on the back of your TV. It's usually the second or third HDMI connector, but the exact location depends on your TV model.
Connect the corresponding ports on the TV and soundbar with a quality HDMI cable. After switching on the devices in the TV menu, you need to activate the CEC (Consumer Electronics Control) function. Different manufacturers call it Anynet+ from Samsung, SimpLink from LG, Bravia Sync from Sony.
☑️ Setting up HDMI ARC
In the TV's audio settings, be sure to select the Outer Speakers or Optical/HDMI output to turn off the internal speaker. If the sound is late, check the audio sync settings in the TV menu. The correct CEC configuration will allow the soundbar to turn on and off automatically along with the screen.
What if the sound is not coming through HDMI ARC?
⚠️ Note: Not all cables HDMI Supports reverse audio channel ARC. Use only certified High Speed cables marked with the logo HDMI, to avoid problems with signal transmission.
Use of optical and analog inputs
Optical Interface (S/PDIF) remains one of the most popular ways to connect audio systems due to its reliability and protection from electromagnetic interference. The cable transmits a signal in the form of light, which completely eliminates tips. To connect, remove the protective caps from the ends of the cable and paste them into the Optical Out ports on the TV and Optical In on the soundbar before the characteristic click.
After the physical connection, you need to switch the soundbar mode. On the remote or device body, press the source select button until the Optical indicator lights up. On the TV, in the audio settings section, you also have to force the digital output to avoid the signal going to the built-in speakers.
If digital outputs are busy, you can use a 3.5mm analog connector (AUX) that is suitable for older TVs or computer monitors. Sound quality will be inferior to digital formats, as the signal undergoes a digital-to-analog conversion inside the TV, which can add noise. However, for watching news channels or YouTube, this is quite enough.
- 💡 Make sure the protective cap is removed from the optical cable before inserting into the port.
- 🔊 In the case of AUX set the volume of the TV on 70-80% noise-reducing.
- ⚙️ In the settings of the soundbar equalizer, you can adjust the balance when connecting analog.
This can be uncomfortable if the TV remote does not have a separate adjustment of the signal level sent to the output.
Wireless connection via Bluetooth
Bluetooth technology allows you to connect the soundbar to a TV, smartphone or tablet without unnecessary wires.It is ideal for temporary use or if the TV is far from the location of the acoustics. Xiaomi Redmi TV Soundbar is equipped with a Bluetooth module, providing a stable connection at a distance of up to 10 meters.
To pair, turn on the soundbar and press the Bluetooth button on the remote or case until the indicator flashes quickly, signaling search mode. On your TV or smartphone, go to Bluetooth settings, find the Redmi TV Soundbar device, and click Connect.
You should also consider that there is a slight latency when transmitting audio over Bluetooth, which is noticeable when playing games or watching action movies. This method is great for music, providing clean stereo. You can also stream music directly from your phone via Bluetooth, using the soundbar as a portable speaker.
💡
If the TV does not support Bluetooth audio, use a Bluetooth adapter with support for the aptX Low Latency codec, connecting it to the optical output of the TV. This will provide a wireless connection with minimal audio latency.
When you connect multiple devices at once, you usually prioritize the last sound you played. To switch between sources, just press the login select button. Remember, Bluetooth uses more power, so you'd better use wired connections for long-term TV listening.
Sound setting and remote control
Once successfully connected, the fine-tuning stage begins. Xiaomi Redmi TV Soundbar's remote control, black as a TV connection, allows you to adjust not only the volume, but also select audio scenarios. Movie, Music, News and Game modes are available, each of which optimizes frequencies for specific content.
Movie enhances the environment and bass, which is critical for watching blockbusters. News releases the average frequencies, making the speakers more legible and clear. Gamers are given a special mode that minimizes signal processing delays, and you can switch between them in real time, evaluating changes in hearing.
The subwoofer feature deserves special attention: the remote has buttons to adjust the low frequency level regardless of the overall volume, which allows you to add meat to the sound when watching fiction or to reduce the booming basses at night so as not to disturb your neighbors. Experiment with settings to find the perfect balance for your room.
💡
Getting the right equalizer setup and sound profile selection is more important than just maximum volume. Adapt the sound to the type of content for better perception.
Possible problems and ways to solve them
In the process of operation, users can face a number of typical problems, the most common of which is the lack of sound after turning on the TV. In this case, check if the correct source of the signal on the soundbar is chosen, sometimes the system does not switch automatically, and manual intervention through the remote control is required.
If the sound is interrupted or wheezing is heard, the problem may be poor quality cable or interference. For HDMI, try replacing the wire with a shorter or different version. When using an optical cable, make sure that it is not compressed or has sharp fractures, as the fiberglass inside is fragile.
The remote control often has a fault with battery discharge or IR contamination. Wipe the front soundbar with a soft cloth. If the remote has stopped responding fully, try resetting the soundbar to the factory settings by clamping down on a certain button combination (as indicated in the instructions).
