Xiaomi’s audio amplifiers are an affordable way to turn a regular speaker system into a powerful audio complex with clean and surround sound. However, many users face difficulties when connecting for the first time: incomprehensible connectors, unclear menu settings or device compatibility issues. This article will help you understand everything from basic connectivity to professionally calibrating sound for a specific room.
We will look at the popular models of Xiaomi amplifiers (for example, Mi). TV Soundbar, Xiaomi Mi Amplifier Pro or Redmi Soundbar, their key features and typical configuration errors, and we will focus on integrating with TVs, smartphones and smart speakers, because it is in conjunction with other devices that the amplifier unlocks its potential. Whether you want to achieve the perfect balance between bass, midband and tops, or connect the system to the Mi Home for voice control, here you will find step-by-step instructions with illustrations and practical tips.
What Xiaomi Amplifiers Are and How They Differ
Xiaomi’s audio product line includes both compact TV soundbars and full-fledged amplifiers for passive acoustics.
- 📺 Soundbars (e.g. Mi) TV Soundbar, Redmi Soundbar – built-in amplifiers with Bluetooth 5.0 support, HDMI ARC They're good for improving the sound of televisions without external speakers.
- 🎛️ Stereo amplifiers (Xiaomi Mi Amplifier Pro, Yeelight Stereo Amplifier) - for connecting passive acoustics (for example, speakers 2.0 or 2.1.
- 🔊 Xiaomi Mi Home Audio Amplifier – compatible with the Mi Home ecosystem, supports voice control via XiaoAI.
Key differences of models are power (30 to 100 W), types of connection (analogue). RCA, digital, HDMI, Bluetooth and additional features (e.g. Dolby Atmos support) DTS). For example, Mi. TV Soundbar delivers 60W of total power with support for virtual surround sound, while Xiaomi Mi Amplifier Pro offers 80W and the ability to connect a subwoofer.
When choosing an amplifier, focus on:
- 🔌 Type of acoustics: for active speakers, an amplifier is not needed, for passive speakers - mandatory.
- 📏 Room size: up to 20 m2 will be enough 30-50 W, for large rooms will require 80 W and above.
- 🎵 Sound sources: if you plan to connect the TV through the HDMI ARC, Check for this connector.
⚠️ Note: Xiaomi amplifiers with Mi Home support (e.g. Yeelight Stereo Amplifier) require a mandatory connection to the application to unlock the full functionality. Without this, some of the settings (e.g. equalizer) will not be available.
Preparation for connection: what will be needed
Before setting up the amplifier, check for all the necessary cables and adapters. A standard delivery kit usually includes:
- 🔌 Power cable (if the amplifier is not an amplifier) USB-nourishable).
- 📶 3.5 mm AUX or RCA-analogue cable.
- 💡 Optical cable (TOSLINK) Digital audio (if supported).
- 📱 Instructions with QR-code for downloading the application (for models with Mi Home).
In addition, it may be necessary to:
- 🔄 HDMI-cable ARC/eARC (TV-connected).
- 🔊 Cables for speakers (if you use passive acoustics).
- 📶 Bluetooth adapter (if your model does not support wireless connection).

Pay special attention to polarity when connecting columns: red connector (+) The amplifier must be connected to the red on the column, black (−) — Not observing polarity will cause phase distortion and sound deterioration.
Basic Amplifier setting: Connection and first start
The connection process depends on the amplifier model and the sound source, and let's look at three of the most common scenarios:
1. Connection to the TV
For modern Xiaomi TVs (or other brands), the best option is to use them. HDMI ARC:
- Connect the port. HDMI ARC on a TV with the appropriate connector on the amplifier.
- In the TV menu go to Settings → Sound. → Sound output and select HDMI ARC.
- Turn on the amplifier and set the signal source on HDMI.
If HDMI ARC No, use an optical cable (TOSLINK) 3.5 mm AUX.
2. Connection to a smartphone or PC
For wireless connection:
- Activate Bluetooth on the amplifier (usually with a button) BT).
- On a smartphone (Android/iOS) or PC find the device in the list of available and connect.
- At the first connection, you may need to enter PIN-code (usually 0000 or 1234).
Use 3.5 mm for wired connection AUX or USB-C (if maintained).
3. Connection of passive columns
If you have a passive acoustic amp (e.g. Xiaomi Mi Amplifier Pro):
- Connect the speakers to Speaker Out connectors (observing polarity!).
- When connecting the subwoofer, use the Subwoofer Out connector.
- Set up a balance between front columns and subwoofer in the amplifier menu.
After you connect, turn on the amplifier and check the sound at minimum volume. If you hear extraneous noises (background, crackling), check the quality of the cables or try another signal source.
💡
If the amplifier doesn’t turn on, check the power supply: some Xiaomi models require an adapter to be installed. 12V/2A, not a standard smartphone charger.
Customization of sound parameters: equalizer, modes and effects
The sound quality depends largely on the right equalizer and the chosen mode. In Xiaomi amplifiers, these parameters can be adjusted:
- 🎛️ Hardware – buttons on the body (usually) EQ, Mode).
- 📱 Mi Home (for compatible models).
Primary sound modes:
| Regime. | Description | When to use |
|---|---|---|
| Movie | Enhances bass and mid-frequency for movies | Viewing movies, series |
| Music | Balance between high and low frequencies | Listening to music |
| News | Emphasizes voices, suppresses basses | News, podcasts, audiobooks |
| 3D | Virtual surround sound | Games, movies with Dolby effects |
For fine tuning, use the equalizer. In the Mi Home app, it is usually represented by sliders for frequencies: 60 Hz (bass), 250 Hz (lower middle), 1 kHz (medium), 4 kHz (upper middle), 16 kHz (top).
Adjustment recommendations:
- 🎵 For hip-hop and electronics, raise 60–100 Hz (bass) and 16 kHz (high hats).
- 🎸 For rock and metal, accent 250 Hz (guitar) and 4 kHz (vocals).
- 🎻 For classics and jazz, leave the sliders in a neutral position or slightly lift 1kHz.
⚠️ Warning: Excessive bass amplification (60-100 Hz) on cheap speakers can cause sound distortion or even damage to speakers. Start with minimum values and gradually increase.

Integration with the Mi Home ecosystem and voice control
Xiaomi Mi Home-enabled amplifiers (e.g. Yeelight Stereo Amplifier) allow you to control sound via an app or voice.
- Connect the amplifier to a 2.4GHz Wi-Fi network (5GHz is not supported!).
- In the Mi Home app, click Add Device and select your model.
- Follow the instructions on the screen to link to your account.
After you connect, you can:
- 🔊 Adjust volume from the phone.
- 🎵 Switch signal sources (e.g., from Bluetooth to Bluetooth) HDMI).
- 🗣️ Control voice via XiaoAI (Teams: "Like music", "Like volume»).
- ⏰ Set up a schedule (such as automatic shutdown at night).
For voice control, make sure that:
- The amplifier and smartphone are connected to the same Wi-Fi network.
- Mi Home settings have enabled access to the microphone.
- The device is tied to one room in the application (e.g., the “Living Room”).
💡
Voice control works only with amplifiers that support MiOT protocol. Check the compatibility of your model on the Xiaomi website.
Common problems and their solution
Even after the right connection, there can be problems, and let's look at typical situations and how to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| No sound. | Wrong signal source | Check the choice of entry (HDMI, Bluetooth, AUX) power-up |
| Crack or background | Poor contact in cables | Reconnect the cables, try other connectors |
| Low volume. | Restriction in source settings | In the menu of the TV / smartphone, check the output level |
| Bluetooth is not working. | The amplifier is already paired with another device | Reset the list of associated devices (click on it) BT 10sec) |
If the amplifier is not defined in Mi Home:
- Make sure it’s connected to 2.4GHz Wi-Fi (not 5GHz!).
- Restart the router and amplifier.
- Update the Mi Home app to the latest version.
- Reset the amplifier to factory settings (reset button on the back).
⚠️ Note: If after updating the firmware amplifier stopped working, try rolling back the version of the software through Mi Home. → Recoil.
Optimization of sound for the room: practical tips
Sound quality depends not only on the amp settings, but also on the acoustics of the room. Here are some tips for improving the sound:
- 🏠 Location of speakers: Front columns should be at ear level when sitting. The distance between the speakers is at least 1.5-2 meters.
- 🔇 Echo absorption: Use carpets, curtains and upholstered furniture to reduce reverb. Avoid empty walls - they reflect sound, creating a hum.
- 🎛️ Calibration: Turn on the test signal (e.g. pink noise) and adjust the volume of each column. Use the microphone built into the amplifier to automatically adjust (if supported).
To check the sound quality, use the test tracks:
- 🎶 Bass: "Bass Test - 30Hz to 80Hz" (YouTube).
- 🎶 Mid-frequency: "Pink Noise" 1kHz".
- 🎶 Top: “High Frequency Test 16kHz".
If you hear a low frequency hum in the room, try:
- Reduce the level of bass in the equalizer.
- Move the subwoofer away from the walls.
- Use acoustic panels to absorb sound.
