Turning the living room into a cozy karaoke bar is one of the most popular features available to owners of modern Smart TVs. Xiaomi and Redmi TVs based on the Android TV operating system provide ample opportunities for multimedia entertainment, including the launch of specialized singing apps. However, unlike conventional TVs, the process of setting up requires attention to detail, especially when it comes to connecting external equipment.
The main challenge users face is not so much finding software as configuring the audio output correctly. Standard settings often result in voice and music being desynchronized, making singing impossible. To avoid echoes and delays, you need to be smart about choosing a microphone and routing the audio signal through the Settings → Sound interface.
In this article, we will take a closer look at the steps to turning your Mi TV into a professional karaoke station, how to install apps, how to connect wired and wireless microphones, and the secrets to fine-tuning the equalizer for perfect sound.
Selection and installation of karaoke applications
The first step to building a home karaoke system is to install the appropriate software. The Google Play Store built into the TV shell offers many options, but not all of them are equally well optimized for remote control. Some applications may require text input, which is inconvenient to do with standard buttons, so it is worth choosing services with support for management via smartphone.
Among the most stable and popular Android TV solutions, there are several leaders, offering extensive downside databases, the ability to form queues of songs and flexible vocal settings. It is important to pay attention to the version requirements of the operating system, since older TV models may not support the latest versions of software.
- 🎤 Yokee is a popular application with a huge library of tracks and the ability to record your performance directly on video.
- 🎤 KaraFun is a professional service with high quality audio and texts synchronized in time.
- 🎤 StarMaker is a social network for singers, allowing you to arrange duets with users from around the world.
The installation process is standard for the Xiaomi ecosystem: you need to find an app store icon on the home screen or in the App menu. After logging into your Google account (if required), just type the service name into the search bar and click “Install”.
Connecting the microphone: wired and wireless options
The quality of your talk depends on how the microphone is connected to the TV. Xiaomi microphones built into the remotes are designed exclusively for voice search and system control, they do not transmit sound to applications. Singing requires an external device connected via ports. USB or 3.5 mm Jack.
Wired microphones with a USB connector are often the easiest solution, and they work on the principle of Plug-and-Play: the TV recognizes the device as the source of audio input automatically, but the length of the cable can limit freedom of movement, which is not always convenient in a large living room.
☑️ Checking the microphone connection
Wireless microphones that work through their own USB-receiver (swipe whistle), also connected to USB-Unlike Bluetooth headsets, these microphones use their own data protocol, which ensures minimal audio latency. Bluetooth microphones can be used, but they often require additional customization in the developer menu or special applications for sound transfer.
⚠️ Note: Do not connect the microphone input (pink connector 3.5 mm) directly to the port AUX Xiaomi TVs usually only have an audio output, not an input, so a direct connection may not work or damage the technique.
Customization of audio output and elimination of delay
The most common problem when setting up karaoke on a Smart TV is out-of-synchronization, you open your mouth and the sound comes late, and that's because of digital signal processing (DSP), which is used by the TV to improve the sound, but which is harmful to karaoke, and to fix that, you have to change the output mode.
Go to the Settings menu, select Sound (or Display & Sound). Find Digital Output or S/PDIF if you use external acoustics. For built-in speakers, you need to find a sound effect mode. Often called Standard, Film or Music. For karaoke, Standard or Manual mode is the best option, where all surround sound effects are disabled.
If the app supports manual delay adjustment (Delay/Lag compensation), use this feature, which allows you to shift the audio track relative to the video, achieving a perfect hit in the clock, in some cases helps to disable the Dolby Audio or DTS function in the system settings.
| Type of connection | Probable delay | Recommended sound mode | Stability |
|---|---|---|---|
| USB-microphone | Low (< 50 ms) | Straight/Raw | Tall. |
| Bluetooth 4.0/5.0 | Medium (100-200 ms) | Music. | Medium |
| USB-receiver) | Minimum | Standard. | Very high. |
| Built-in microphone | Not applicable. | Anybody. | It's not working. |
💡
If the sound delay is still present, try to turn on the Game mode in the TV settings (Development) or turn off all image enhancements, as they also affect the overall system lag.
Using Smartphones as a Microphone
If you don't have karaoke equipment, you can use your smartphone as a microphone. Many modern applications, like Smule or Yokee, have a synchronization function with your mobile device. The phone acts as both a microphone and a remote control, and the TV displays a clip and text.
To implement this scheme, both devices — a Xiaomi TV and a smartphone — must be on the same Wi-Fi network. In the application on the TV, the option “Connect Mobile” or similar is selected, and then scanned. QR-The smartphone connects to the TV, and the sound starts to be broadcast through it, or (less often) the TV captures the audio from the phone.
However, it is worth considering that in this scheme, the sound is often output through the phone’s speaker, rather than through the powerful acoustics of the TV. To sing through the TV, using the phone as a microphone, you will need third-party audio transfer software, such as the SoundWire app or using the Google Home feature to broadcast the sound, which can add additional delay.
The secret to low latency Xiaomi
Set up the equalizer and effects for vocals
Once the hardware is connected and the delay is fixed, it's time for the creative part. Xiaomi's built-in audio settings allow you to base the equalizer on, and while they're not a substitute for a professional mixer, they can make your voice clearer and more enjoyable.
In the audio effects menu, select manual tuning. For vocals, it is recommended to raise the high frequencies (for diction clarity) and the middle frequencies a little. Low frequencies (bass) should be reduced a little so that the voice does not “buzz” and is not lost in the powerful music. If there is a built-in equalizer in the application, it is better to use it.
Also, look at Auto Volume or Night Mode, which is something that you should turn off for karaoke, and they dynamically change the volume of quiet and loud sounds, which causes unpredictable surges in the voice level during a song, and the volume should be fixed.
⚠️ Attention: Don't maximize the sensitivity of the microphone. This will cause an unpleasant whistle (acoustic feedback), when the sound from the speakers again hits the microphone and amplifies in a circle. Find a balance where the quiet whisper is heard, but the background noise does not cause a squeal.
Frequent problems and ways to solve them
Even when set up correctly, there can be technical difficulties. One of the common problems is that there is no sound in the app, although other services (YouTube, Netflix) do. This indicates codec conflict or no permissions. Go to Settings → Applications, find your karaoke application and check the permissions. Make sure that access to the microphone and storage is allowed.
Another common situation is that the app crashes when you run a heavy song with a 4K video. Xiaomi TVs have limited RAM, in which case it helps to clear the app's cache or close the background programs. Also try to reduce the video quality in the settings of the karaoke application itself, if this option is available.
- 🛑 No sound: Check if the TV is set to "Subwoofer Only" or "Optical Output" mode without the connected system.
- 🛑 Quiet voice: Make sure that the microphone volume is not turned to zero in the app settings (often separate from the music volume).
- 🛑 Lags of the interface: Reboot the TV full cycle (turn off the socket for 10 seconds), this will clear the RAM.
If problems persist, try installing an alternative media player or tablet version of the app (through third-party stores like Aptoide TV), as the Android TV version is sometimes buggy.
💡
The key to success is using wired USB-microphone and disable all digital audio enhancements (Dolby, DTS) In the settings of the TV to minimize delay.
