Using a Xiaomi TV not only for watching movies, but also for karaoke, online conferences or voice control often requires the connection of additional equipment. Standard remotes have built-in microphones, but their sound quality leaves much to be desired for recording or singing. Users who want to expand the functionality of their Android TV are faced with the question of choosing the right way to input sound.
Unlike smartphones, where connectors are standardized, Xiaomi TVs offer a limited set of ports, which requires careful accessory selection. In this article, we will look at all possible connectivity options, from simple wired solutions to complex wireless circuits. You will learn how to turn your TV into a full-fledged multimedia center with quality audio input.
Modern models such as the Xiaomi Mi TV P1 or Mi Box S run on Android, which opens up a lot of possibilities for peripheral integration. However, the physical presence of a USB port does not always guarantee the microphone will work automatically in the desired application.
Analyzing available interfaces for audio input
The first step before buying equipment is to carefully study the back of your device. Xiaomi TVs usually come with multiple USB 2.0 and USB 3.0 ports, as well as a 3.5mm headphone jack. It is important to understand that most models do not have a separate line-in for the microphone, so the standard 3.5mm jack will not work directly.
The main interface for connecting external input devices in the MIUI for TV ecosystem is the USB bus. It is through this port that the system receives digital audio data. If you plan to use professional equipment, you will need an external audio interface or sound card that also connects via USB.
Why is the 3.5mm connector not working?
Some users try to use Bluetooth headsets, but here lies the caveat: the TV can recognize the device as headphones, ignoring the built-in microphone of the headset. USB-Connection remains the most stable and versatile solution for problems requiring low sound latency.
Connection USB-microphone
The easiest and most efficient way is to use a USB microphone, which includes a built-in sound card that takes over the digitization of audio. Xiaomi Android TVs typically automatically recognize these devices as standard input sources.
To connect, simply insert the microphone plug into any free USB port on the back or side of the TV. The system must emit the characteristic sound of the device's connection. In most cases, the drives are already built into the Android TV operating system kernel.
☑️ Checking of operability USB-microphone
But not all of them. USB-Some models require power that may be lacking in the TV port, or use specific data protocols. USB-powerhouse.
💡
Use USB ports with blue insert (USB 3.0) if they are available, as they provide more stable data transfer and often have better current output to power the periphery.
Use of wireless Bluetooth microphones
Wireless connectivity eliminates unnecessary wires, but requires the right pairing setup. Xiaomi TVs support Bluetooth 4.0 and higher, allowing you to connect headsets and specialized microphones. Go to Settings menu → Remotes and accessories → Add accessory to start the search.
Importantly, when you connect a Bluetooth headset, the TV can only use it to output sound by default, so in order for the microphone to work, you need to press the gear icon next to the connected device in Bluetooth settings and make sure that the permission to use the microphone is active.
- 🎤 Enable pairing mode on your Bluetooth microphone (usually by pressing the power button).
- 📺 On the remote, press the button "Menu" and select the system settings section.
- 🔍 In the list of available devices, find the name of your microphone and pair.
- ⚙️ Check in the app you are using if a Bluetooth sound source is selected.
There is a problem with latency when using Bluetooth, and for karaoke, this can be critical because the voice will lag behind the music, and in such cases, it is preferable to use a wired connection or specialized radio systems with a radio system. USB-receiver operating at 2.4 GHz frequencies.
Application of external sound cards and interfaces
For professional use, such as streaming or recording podcasts, built-in capabilities may not be enough. USB, They allow you to use high-quality phantom-powered condenser microphones. USB-audio-device.
When choosing a sound card, pay attention to Android compatibility. Devices that work in the UAC2 class (USB Audio Class 2) have the best compatibility. Popular models from Focusrite or Behringer often work out of the box, but may require external power.
💡
External sound card through USB — The only solution for connecting professional XLR-Xiaomi TV microphones without loss of sound quality.
The Gain level is set either on the sound card body itself or through a specialized application if it is available in the Google Play Store on your TV. Standard Android TV tools often do not provide fine-tuning of the sense of entry.
Configuring sound parameters in the Android TV system
Once the device is physically connected, you need to make sure that the system has correctly assigned roles. Go to Settings → Device → Sound. This can display a list of available input and output devices. If the microphone is defined as an output device, the sound can go into it, not from the speakers.
In some cases, you need to install third-party audio management applications, such as Lesser AudioSwitch or analogues available in the app store. USB-microphone, ignoring the built-in remote sensors.
| Type of connection | Sound delay | Quality. | Difficulty setting up |
|---|---|---|---|
| USB-microphone | Minimum | High. | Low. |
| Bluetooth headset | Tall. | Average. | Medium |
| USB Sound Card | Minimum | Professional | Tall. |
| Radio system 2.4 GHz | Low. | High. | Low. |
Remember to check the permissions for applications. When you run a karaoke or video call program for the first time, the system will ask permission to use the microphone, and denying access will cause even the proper hardware to fail.
Troubleshooting and troubleshooting
A common problem is the lack of sound when using cheap ones. USB-This may be due to an audio format that is not supported by the TV. Try changing the settings in the app if you can, by choosing 16-bit, 44100 Hz or 48,000 Hz.
⚠️ Warning: If the microphone is missing from the TV speakers, check the output settings. The system could automatically switch the output to the connected device, even if it is only a microphone.
And the power problem is also worth mentioning: If the microphone has an LED light and it doesn't burn or blink, the TV doesn't have enough current in the port. USB. Use it. USB-hub with additional power or connect the microphone to the port with the marking USB 3.0.
In rare cases, rebooting a TV with an already connected microphone helps. Android TV doesn't always properly handle hot audio connection. Turn the TV off the socket for 10 seconds, then turn it on again.
Applications for working with the microphone on Xiaomi TV
Apps will be needed to realize the potential of connected hardware. StarMaker or Smule, which have Android TV versions, are popular for karaoke. Zoom or Skype can be used for video communication, although their functionality on TVs may be limited.
There are also specialized microphone testing tools that allow you to visualize the level of the incoming signal, which is useful for adjusting the sensitivity and position of the microphone relative to the sound source, and you can download them through the built-in Google Play store.
⚠️ Note: When installing applications from unknown sources (APK-Be careful, untested programs can access your microphone and broadcast sound without your knowledge.
Some apps require a paid subscription to use voice recording or karaoke. Please read the terms of use of the service before installing. Free versions often have recording time limits or song count limits.
