Connect the power supply to the socket (not to the USB-port)-->

Critical error: If, after connecting, AUX Sound is distorted or you hear interference, and check if the TV settings are "Accelerated for the hearing-impaired" or "Night mode," which changes the frequency response of the signal, leading to wheezing on the amplifier.

3. Setup Xiaomi Amplifier Pro with smartphone: Bluetooth and wired connection

The Xiaomi Amplifier Pro can be used not only with a TV, but also with a smartphone — it's a great solution for listening to music with powerful sound. Consider both Bluetooth and wire connections.

For devices with USB-C (for example, Xiaomi 13/14, Samsung Galaxy S23) You'll need an adapter. USB-C → 3.5 Note: Not all adapters support audio output – avoid cheap models without a chip. DAC.

💡

If the Bluetooth connection interrupts the sound, try to reduce the bitrate in the Bluetooth codec settings (select SBC instead AAC It'll lower the quality, but it'll eliminate the cliffs.

4. Connecting to a computer or laptop: setting up Windows and macOS

Using the Xiaomi Amplifier Pro from PC opens up new possibilities for gamers and music lovers, but there are nuances to this, especially if you want to achieve minimal sound delays (important for games and videos).

• 🔊 Open System settings → Sound. → Conclusion.
• 🔄 Select 3.5mm Audio Drive and adjust the balance.
• ⚙️ In Settings MIDI Turn off the sound processing (in/out) → Set-up of the device → Use sound effects: No).

For gamers: if you connect the amplifier to a PC for games, in the sound card settings (Realtek Audio Console or similar) disable all spatial sound effects (Dolby Digital, DTS). They add delay, which is critical in shooters.

5 Common Problems and Solutions: Why There Is No Sound or No Interference

Even with the right connection, there can be problems, and we've collected the most common cases and ways to fix them.

Problem 1: No sound at all

• 🔌 Reconnect all cables – sometimes contacts oxidize.
• 📛 Check if the sound on the amplifier itself is turned off (Mute button on the back panel).

Problem 2: There is sound, but with noise/wheezing

Problem 3: The booster is warming or turning off

⚠️ Warning: If the Amplifier Pro case is heated above 60°C (hand can't be touched), immediately disconnect it from the mains. This is a sign of short circuit in the speakers or power supply. Check the resistance of the speakers (must be 4-8 ohms) and the integrity of the cable insulation.

💡
