Modern operating system TVs Android TV provide users with a wide range of options for customizing their multimedia experience, but audio settings often remain underappreciated. Many owners are content with the factory settings, not suspecting that the built-in audio processor can radically change the perception of a movie or music. The correct configuration of frequencies allows you to compensate for the shortcomings of the built-in speakers and adapt the sound to the acoustic characteristics of your room.
In this article we will analyze in detail the process of fine-tuning the audio path of your device. You'll learn how to access hidden menus, which settings control dialogue clarity, and which control bass depth. We will also look at third-party solutions for cases where the standard functionality of the system is not flexible enough for your needs.
Before you start changing any parameters, it is worth understanding the basic principle of the digital equalizer. This is a tool that allows you to enhance or attenuate certain frequency bands, forming the final timbre sound. Incorrect intervention can lead to distortion or even damage to the speakers under extreme loads, so the approach must be balanced and consistent.
Access to system sound settings
The first step towards ideal sound is to search for the appropriate section in the operating system interface. The path may differ slightly depending on the TV manufacturer (Sony, Philips, Xiaomi, TCL) and shell version Android, but the general menu logic remains the same. You need to open the main menu and find the gear-shaped icon, which indicates the global settings of the device.
Inside the settings section, you should look for an item related to sound or display. Most often it is simply called Sound or Display & Sound. This is where the main audio stream control levers are concentrated. If you use a remote control with voice control, you can simply say the command “Sound Settings” so that the system will automatically redirect you to the desired section.
⚠️ Attention: In some budget TV models, the manufacturer can completely block access to the manual equalizer, leaving only a selection of ready-made presets. This is a hardware-level limitation that cannot be circumvented using software methods without obtaining root access.
After entering the sound menu, you will see a list of available options, which may include environment modes, channel balance and, in fact, the equalizer. To activate advanced settings, sometimes you need to switch the sound mode from “Standard” to “Custom” or Custom. Only in this mode do the frequency sliders become active for editing.
Manually adjusting equalizer frequencies
When you are in the manual control menu, a graph or set of sliders will open in front of you, each of which corresponds to a specific frequency band. Understanding what each band does is key to a good setup. Typically, the range is divided into low, mid and high frequencies, allowing you to influence specific aspects of the sound picture.
Low frequencies, often designated as Bass (20 Hz - 250 Hz), are responsible for the depth and power of sound. Increasing these values will add weight to explosions in action movies and rhythm in music, but too much gain can cause the TV cabinet to rattle. Mid frequencies (250 Hz - 4 kHz) are the most important for the intelligibility of human speech, this is where the secret of clear dialogue lies.
- 🎚️ Low frequencies (Low): Responsible for volume and power, requires careful increase to avoid wheezing.
- 🗣️ Mid frequencies (Mid): Critical for vocals and dialogue, their correction improves understanding of the plot.
- 🔔 High frequencies (High): Add airiness and detail to the sounds of nature, glass and high-pitched instruments.
High frequencies (4 kHz – 20 kHz) add “air” and detail to the sound. If the sound seems dull or dull to you, a smooth increase in this range can refresh the picture. However, be careful: an excess of high frequencies makes the sound harsh and tiring for the ear during prolonged viewing.
When adjusting the equalizer, move the sliders slowly, in 1-2 dB steps, and immediately evaluate the result on a familiar fragment of a movie or track. Sharp jumps in values often lead to unnatural sound.
Use of ready-made sound profiles
For users who do not want to delve into technical details, the developers have provided a set of preset modes. These profiles, such as Cinema, Music, Sports or News, already contain optimized equalizer curves for specific types of content. Selecting the right profile may take seconds, but will give a noticeable increase in quality.
Mode Cinema usually expands the dynamic range, emphasizing the low frequencies for special effects and highlighting the center channel for dialogue. Profile Music, on the contrary, tries to make the sound smoother and more natural, maintaining a balance between instruments. Sports mode often focuses on announcers' comments and stadium sounds, cutting out unnecessary noise.
| Mode | Main goal | Characteristics frequencies |
|---|---|---|
| Standard | Universal use | Smooth frequency response, without pronounced accents |
| Cinema | Watching films and TV series | Amplified bass, highlighted mids |
| Music | Listening to audio tracks | Extended range, emphasis on detail |
| Sports | Broadcasts of matches | Priority to the commentator's voice, presence effect |
It is worth noting that the effectiveness of these profiles directly depends on the quality of the built-in speaker system. On top models with a subwoofer, the Cinema mode will be fully revealed, while on compact panels it can only add artificial hum. Experiment with switching modes in real time to find the most comfortable option for your hearing.
The problem of quiet dialogue and loud effects
One of the most common complaints of Android TV owners is the imbalance of volume: explosions and music sound deafening, and the speech of actors is barely audible. This problem is often associated with the coding features of multi-channel audio Dolby Digital or DTS, when the center channel with dialogue is much quieter than the effects channels.
To solve this dilemma, the sound settings often contain a function called Night Mode, Auto Volume or Dynamic Range Compressor. Enabling this option compresses the difference between the quietest and loudest sounds, making dialogue audible without having to constantly turn the volume with the remote control.
⚠️ Warning: Enabling the dynamic range compressor may reduce the overall emotionality of the soundtrack, making the film less "dramatic". Use this function selectively, for example, only for night viewing.
If the built-in tools are not enough, you can try changing the audio output format. Switching from Auto or Bitstream to PCM forces the TV to decode the sound itself, which sometimes improves channel balance due to internal processing of the TV processor, rather than external acoustics.
Why might sound be better in PCM mode?
PCM mode transmits an already decoded stereo signal. The TV itself applies its own sound scaling algorithms to the built-in speakers, which often gives a more predictable and balanced result compared to transmitting the raw bitstream to external devices, which may incorrectly process channel mixing.
Connecting external acoustics and sound bars
The built-in speakers of TVs, even the most expensive models, have physical limitations in size and power. For truly high-quality sound, it is recommended to connect external acoustics: sound bars, home theaters or stereo systems. Android TV supports various connection protocols, each of which affects the final quality.
The most modern and preferred interface is HDMI ARC or its improved version eARC. This protocol allows you to transmit lossless multi-channel audio and control the volume of the sound bar using the TV remote control. When connected via HDMI, the system automatically recognizes the device and can offer optimized equalizer settings for external acoustics.
- 🔌 HDMI ARC/eARC: Best quality, support for all modern formats, control with one remote control.
- 🔵 Optical (S/PDIF): Good quality, but limited to Dolby Digital and DTS formats, no support for the latest codecs.
- 📶 Bluetooth: Wireless convenience, but there may be audio delay (lag) and loss of quality during compression.
When using Bluetooth headphones or speakers, it is critical to check for audio latency. In the developer settings or in the special sound section of some TVs there is a latency correction option Audio Delay. If there is no such option, and lip-synchronization is noticeable, it may be worth considering a wired connection or a higher-quality Bluetooth adapter with codec support. aptX Low Latency.
Using an HDMI cable with eARC support guarantees the best synchronization of audio and video, and also allows you to transfer object-oriented formats like Dolby Atmos without loss.
Third-party applications for advanced configuration
If the standard functionality of Android TV seems limited to you, the Google Play ecosystem offers a number of applications that can expand the capabilities of the audio processor. apps such as Equalizer FX or Bass Boosterinstall as regular applications and intercept the audio stream, applying their own processing algorithms before outputting to speakers.
Installing a third-party equalizer requires granting the application special permissions to access system audio. Once activated, you get access to more detailed graphs, the ability to save your own presets, and apply effects like Surround Virtualization or Reverb. This is especially true for older TV models, where the performance of the built-in processor does not allow the implementation of complex algorithms.
However, it is worth remembering the resource intensity of such solutions. Running a heavy audio processor in the background can increase the load on the device's RAM, which in rare cases leads to the interface slowing down. It is recommended to test applications one by one, removing those that do not provide a noticeable increase in quality or consume too many resources.
⚠️ Attention: Third-party applications may conflict with system sound settings. If, after installing the equalizer, the sound disappears completely or strong noise appears, uninstall the application and restart the TV.

Frequently asked questions and troubleshooting
During the setup process, users often encounter typical situations that raise questions. Below are answers to the most popular ones that will help you avoid common mistakes and quickly restore the functionality of your audio system.
Why, after tuning, the sound became quieter than before?
This can happen if you lowered too many frequency bands at the same time or activated the night listening mode. Check if the overall gain level (Pre-amp) is set to minus. Return the sliders to the neutral position (0 dB) and adjust the volume again.
Is it possible to adjust the equalizer for each application separately?
This cannot be done using standard Android TV tools; the settings are applied globally to all sources. However, some third-party equalizer applications have a feature of profiles that can be switched manually depending on whether you are watching YouTube or running a game.
What should you do if the equalizer menu is grayed out?
Most likely, you have selected an audio source that does not support processing (for example, an external decoder via optics in Bitstream mode). Try switching the digital output to PCM in the sound settings or changing the sound profile to “Standard” or “Custom”.
Does the equalizer setting affect the sound delay?
Sophisticated digital signal processing always introduces minimal delay. This is not noticeable on the built-in speakers. But when using Bluetooth headphones, complex equalizer settings can increase desync. In this case, use simplified presets.
Are settings reset after a firmware update?
In most cases, custom equalizer settings are saved after a system update. However, if the update was major (change of Android version), a reset to factory settings is possible. It is recommended to photograph successful settings before updating the software.
