In the era of home entertainment, soundbars have become an essential component of many living rooms. They provide an immersive audio experience, elevating the overall enjoyment of movies, TV shows, and video games. One of the key features that make soundbars so appealing is HDMI passthrough. But have you ever wondered how it works? In this article, we’ll delve into the inner workings of HDMI passthrough on a soundbar, exploring its benefits, advantages, and limitations.
What is HDMI Passthrough?
HDMI passthrough, also known as HDMI bypass or audio return channel (ARC), is a feature that allows a device to pass through the audio signal from a source device, such as a Blu-ray player or gaming console, to a TV or display, while simultaneously processing the audio signal for playback through the soundbar. This feature eliminates the need for multiple HDMI cables, making it a convenient and space-saving solution for home entertainment systems.
How Does HDMI Passthrough Work?
To understand how HDMI passthrough works, let’s break down the process into three stages:
The source device, such as a Blu-ray player or gaming console, sends an audio signal to the soundbar via an HDMI cable. The audio signal is typically encoded in a specific format, such as Dolby Atmos or DTS:X.
The soundbar receives the audio signal and processes it using its internal audio processing capabilities. This may involve decoding the audio format, applying sound enhancements, and adjusting the audio settings according to the user’s preferences.
The processed audio signal is then passed through the soundbar to the TV or display via another HDMI cable. The TV receives the audio signal and displays the accompanying video signal, creating a seamless viewing experience.
The Key Benefit: Simplified Connectivity
HDMI passthrough simplifies the connectivity process by reducing the number of cables required. Without HDMI passthrough, you would need to connect the source device to the TV and then connect the TV to the soundbar, resulting in a tangled mess of cables. With HDMI passthrough, you can connect the source device to the soundbar and then connect the soundbar to the TV, creating a cleaner and more organized setup.

HDMI passthrough allows you to connect multiple devices to the soundbar, making it easy to switch between different sources without having to reconfigure the entire system.
Reduced Clutter
As mentioned earlier, HDMI passthrough reduces the number of cables required, resulting in a cleaner and more organized setup.
Limitations of HDMI Passthrough
While HDMI passthrough is a convenient feature, it’s not without its limitations:
Compatibility Issues
HDMI passthrough may not work with all devices or TVs, particularly older models. It’s essential to check the compatibility of your devices before purchasing a soundbar with HDMI passthrough.
Audio Format Restrictions
Some soundbars may not support all audio formats, such as Dolby Atmos or DTS:X. This can limit the audio quality and may result in a reduced audio experience.
Video Signal Delay
HDMI passthrough can introduce a slight delay between the video signal and the audio signal, which can result in lip-sync issues. However, this is typically only noticeable in certain situations and can be mitigated by adjusting the audio delay settings on the soundbar or TV.
Conclusion
HDMI passthrough is a powerful feature that simplifies the connectivity process and enhances the overall audio experience. By understanding how it works and its advantages and limitations, you can make an informed decision when purchasing a soundbar for your home entertainment system. Remember to check the compatibility of your devices and consider the audio formats supported by the soundbar to ensure a seamless and immersive audio experience.

What is HDMI Passthrough on a Soundbar?
HDMI passthrough on a soundbar is a feature that allows the soundbar to pass through video signals from an HDMI source, such as a Blu-ray player or gaming console, to a TV, while simultaneously processing the audio signal. This means that the soundbar acts as a bridge between the HDMI source and the TV, allowing the video signal to pass through untouched, while enhancing the audio experience. HDMI passthrough is often referred to as “HDMI pass-through” or “HDMI bypass”.
By using HDMI passthrough, you can connect multiple devices to your soundbar, and then connect the soundbar to your TV using a single HDMI cable. This simplifies the connection process and reduces clutter, making it an attractive feature for those with complex home entertainment systems. Additionally, HDMI passthrough can also help to reduce the complexity of switching between different devices, as you can control the soundbar’s input source separately from the TV’s input source.
How Does HDMI Passthrough Work on a Soundbar?
HDMI passthrough works by using an HDMI input on the soundbar to connect to an HDMI source, such as a Blu-ray player or gaming console. The soundbar then processes the audio signal from the HDMI input, enhancing it with features such as Dolby Atmos or DTS:X, and outputs it through its speakers or subwoofer. At the same time, the soundbar passes the video signal from the HDMI input through to an HDMI output, which is then connected to the TV. The TV receives the video signal and displays it, while the soundbar handles the audio.
The soundbar’s HDMI passthrough feature is often controlled using a remote control or on-screen menu, which allows you to switch between different input sources, adjust audio settings, and customize the soundbar’s performance. Some soundbars may also offer additional features, such as auto-detection of HDMI sources or audio signal processing, to enhance the overall audio-visual experience.
What Are the Benefits of HDMI Passthrough on a Soundbar?
One of the main benefits of HDMI passthrough on a soundbar is that it simplifies the connection process between multiple devices and a TV. By using a single HDMI cable to connect the soundbar to the TV, you can reduce clutter and make it easier to switch between different devices. HDMI passthrough also allows you to upgrade your sound system without having to upgrade your TV, as you can connect newer devices with advanced audio features to your existing TV.
Another benefit of HDMI passthrough is that it can improve the overall audio-visual experience. By processing the audio signal separately from the video signal, the soundbar can enhance the audio experience with features such as surround sound or Dolby Atmos, while the TV focuses on displaying the video signal. This can result in a more immersive and engaging viewing experience.
