Modern TVs are getting thinner, which inevitably affects the quality of the built-in audio, making it flat and devoid of bass. That is why owners of equipment often think about buying external acoustics, and the Xiaomi Redmi TV Soundbar becomes a great choice. This device can radically change the perception of cinema and music, filling the room with surround and clear sound that is not available to regular speakers.
The process of pairing this speaker system with your screen does not require special technical knowledge, but has its own nuances depending on the selected signal transmission interface. In this article, we will discuss in detail all possible ways of switching, from wired options with maximum bandwidth to wireless solutions for maximum convenience.
You will learn how to adjust the volume control from the TV remote, which cables are best used for different TV models and how to avoid common errors during the initial installation. Competent connection will allow you to unlock the full potential of the audio system and ensure that the picture and sound synchronize without delay.
Choosing the optimal connection interface
Before you start physical switching, you need to carefully examine the connectors available on the back or side of your TV. The type of available port directly affects the quality of the audio stream transmitted and the convenience of further operation of the system. The most preferred option for modern models is the use of the HDMI ARC digital interface.
This standard allows you to transmit high-resolution multichannel sound and, most importantly, allows you to control the soundbar volume directly from the TV remote. If your TV was released several years ago and does not support audio backflow technology, you should pay attention to Optical (Toslink) optical output, which also provides excellent digital quality.
⚠️ Note: Do not use analogue cables (tulips) RCA) to connect if your equipment has digital inputs, as this will lead to loss of signal quality and the inability to decode modern sound formats.
Owners of older TVs that do not have HDMI or optical output will have to use analog connection via a 3.5 mm connector or RCA. In this case, the soundbar volume control will be carried out only through its own remote or buttons on the case, which is less convenient in everyday use.
Connection via HDMI ARC
The HDMI ARC (Audio Return Channel) interface is the gold standard for home multimedia equipment. To implement this method, you will need a high-quality HDMI cable version 1.4 or higher that is capable of passing enough data for an uncompressed audio stream.
Find a connector on the back of your TV that is HDMI (ARC) or simply ARC. It is usually located separately from the other ports or is marked accordingly. Insert one end of the cable into this TV port and the other into the corresponding socket on the soundbar of Xiaomi Redmi TV Soundbar.
After the physical connection, you need to activate the function in the TV menu. Go to the audio settings and select an external speaker or HDMI system as the output device. Some models require additional CEC (Consumer Electronics Control) option to enable the TV remote control to control the power and volume of the soundbar.
☑️ Connection check HDMI ARC
The advantage of this method is that it supports formats like Dolby Digital and DTS, which is critical for watching movies from disk or streaming services. If the sound does not appear immediately, try rebooting both devices by disconnecting them from the power grid for 10-15 seconds.
What if there is no sound through HDMI?
Use of Optical Cable (Toslink)
If the HDMI port is busy or your TV model does not support the return of audio stream, the optimal solution is an optical connection. Toslink cable transmits a digital signal using light, which completely eliminates the occurrence of electromagnetic tips and provides the cleanest sound.
To connect, take an optical cable and remove the protective plugs from its tips. Carefully insert the plug into the Optical Out port on your TV and into the Optical In port on the soundbar. A characteristic click when inserted will confirm that the connection is fixed correctly.
In the TV sound system settings, you need to choose the optical output as the main one, and it is important to note that it is often impossible to transmit sound in formats higher than Dolby Digital 5.1 through this interface, so for maximum quality in the TV settings, you should set the output format PCM or Auto.
| Parameter | HDMI ARC | Optical (Toslink) | Bluetooth |
|---|---|---|---|
| Sound quality | Maximum (Lossless) | High (Compressed) | Average (Depends on the codec) |
| Control from the remote | Yes (via CEC) | Partially (depends on TV) | No (loudness only) |
| Support for formats | Dolby Atmos, DTS:X | Dolby Digital 5.1 | SBC, AAC, aptX |
| Stability | Tall. | Tall. | Medium (probable interference) |
Optical connectivity ensures no delays, which is especially important when watching dynamic scenes or games. Make sure the cable is not clamped and has no sharp breaks, as the fiber inside can damage.
💡
Optical cable is the best choice for older TVs, providing stable digital sound without the interference typical of analog connections.
Wireless connection via Bluetooth
The easiest but less efficient way to switch is to use Bluetooth technology, which is ideal for listening to music from a smartphone or connecting to a TV that has a broken audio output, but consider possible delays when watching videos.
To pair, put the Xiaomi Redmi TV Soundbar soundbar in standby mode. Press and hold the source select button until the indicator flashes blue, signaling readiness to search for devices. On your TV or smartphone, turn on Bluetooth and start scanning.
In the list of available devices, find Redmi TV Soundbar and click on it to connect. Once successfully paired, the indicator on the soundbar body will stop flashing and light up with even light. The sound quality in this mode depends on the codecs supported: SBC provides basic quality, and aptX or AAC give a more detailed picture.
⚠️ Attention: When connected via Bluetooth, you can desynchronize sound and image (lip-sync error). If the actors' lips do not hit the beat of the voice, find the "Sound Delay" setting in the TV settings and adjust it.
The disadvantage of the wireless method is compressing the audio stream, which loses subtle nuances and dynamics. In addition, the range of Bluetooth frequencies is limited, so deep bass can sound less expressive compared to a wired connection.
Customization of sound modes and equalizer
Once successfully connected, you need to adjust the sound settings to your preferences and acoustic features of the room. The Xiaomi Redmi TV Soundbar offers several pre-installed modes that can be switched using the remote or buttons on the body.
Standard Mode is suitable for everyday TV and news watching, providing balanced sound. For watching movies with a lot of special effects, it is better to switch to Movie mode, which expands the sound scene and amplifies low frequencies.
If you're planning on listening to music, activate Music Mode, which focuses on the purity of vocals and instruments, making the sound more detailed and airy, and some models allow you to manually adjust the equalizer through the Mi Home app.
💡
Place the soundbar strictly in the center under the TV at least 10 cm from the wall to avoid the resonance of low frequencies and humming.
Remember that the soundbar position also affects the perception of sound. Make sure that the speakers' output holes are not covered by decorative nightstand elements or other interior items.
Addressing common problems
During operation, users may experience no sound or periodic interruptions of the signal. Often the problem lies in the incorrect output format in the TV settings. Try changing the audio settings from Bitstream to PCM or vice versa.
If the soundbar doesn’t respond to the TV’s remote commands, check whether external device control (CEC) is included in the TV menu. It’s also worth checking the batteries in the soundbar remote, as a weak charge can cause IR receiver malfunctions.
If there is background noise or cod, check the integrity of the cables. Poor contact in the connector or damage to the insulation of the wire can cause interference. In the case of Bluetooth, interference can be caused by other wireless devices operating nearby.
