The world of home entertainment has witnessed significant advancements in recent years, with a growing focus on creating an immersive experience for users. One of the key technologies driving this revolution is Dolby Atmos, an innovative audio format that has taken the entertainment industry by storm. While many are familiar with Dolby Atmos, there’s a crucial aspect of this technology that often gets overlooked – Dolby Atmos passthrough. In this article, we’ll delve into the world of Dolby Atmos passthrough, exploring its significance, benefits, and how it enhances the overall audio experience.
What Is Dolby Atmos?
Before diving into passthrough, it’s essential to understand what Dolby Atmos is. Dolby Atmos is an object-based audio format that allows sound designers to pinpoint audio elements in a three-dimensional space. This means that sound can be placed and moved in specific locations, creating a more realistic and immersive experience for the listener. Unlike traditional surround sound systems that only provide a static, channel-based audio experience, Dolby Atmos introduces height channels, allowing sounds to emanate from above, in addition to the sides and rear.
Dolby Atmos is not limited to cinemas; it has also become a staple in home entertainment systems, with many streaming services, Blu-ray discs, and game consoles supporting the format. However, to fully appreciate the capabilities of Dolby Atmos, it’s essential to understand the concept of passthrough.
What Is Dolby Atmos Passthrough?
Dolby Atmos passthrough is a feature that allows audio/video receivers (AVRs) and soundbars to pass through the original Dolby Atmos audio signal from a source device, such as a Blu-ray player or gaming console, to a television or display device. This means that the audio signal remains untouched, without being decoded or processed by the AVR or soundbar, ensuring that the original audio information is preserved in its entirety.
Passthrough is crucial for maintaining the integrity of the Dolby Atmos signal, as it prevents any potential loss of audio data or quality degradation that may occur during the decoding process. In essence, Dolby Atmos passthrough ensures that the audio signal is transmitted in its purest form, allowing the display device to decode and process it correctly.
How Does Dolby Atmos Passthrough Work?
The passthrough process involves a few key steps:
- The source device, such as a Blu-ray player or gaming console, encodes the audio signal in Dolby Atmos format.
- The encoded audio signal is transmitted to the AVR or soundbar via an HDMI connection.
- The AVR or soundbar recognizes the Dolby Atmos signal and passes it through to the display device, without decoding or processing it.
- The display device, which supports Dolby Atmos, decodes and processes the audio signal, rendering it in its native format.
This passthrough process ensures that the audio signal remains untouched, preserving the original audio information and maintaining the highest possible quality.
Benefits Of Dolby Atmos Passthrough
So, why is Dolby Atmos passthrough so important? Here are some key benefits:
Pristine Audio Quality
By passing through the original Dolby Atmos signal, AVRs and soundbars ensure that the audio quality remains unaltered, preserving the nuanced details and subtle textures that make the format so immersive.

What Is Dolby Atmos Passthrough?
Dolby Atmos Passthrough is a technology that allows audio signals to pass through a device, such as a TV or soundbar, without being decoded or processed. This means that the device simply forwards the original audio signal to the next device in the chain, without altering it in any way. This is in contrast to traditional audio processing, where the device would typically decode and process the audio signal before sending it to the next device.
By not processing the audio signal, Dolby Atmos Passthrough ensures that the original audio quality is preserved, maintaining the full range of immersive audio effects and nuances. This is particularly important for Dolby Atmos content, which is designed to provide a truly immersive audio experience. By passing the audio signal through without processing, devices can ensure that the full Dolby Atmos experience is maintained, with all its height channels, object audio, and other immersive features.
What Is The Difference Between Dolby Atmos Passthrough And Dolby Atmos Decoding?
Dolby Atmos Decoding refers to the process of decoding and processing the audio signal to extract the Dolby Atmos metadata and audio objects. This process involves the device, such as a TV or soundbar, interpreting the audio signal and extracting the individual audio objects and channels. The device then processes the audio signal to create the immersive audio experience.
In contrast, Dolby Atmos Passthrough bypasses this decoding and processing step, instead simply forwarding the original audio signal to the next device in the chain. This allows devices that are not capable of decoding Dolby Atmos to still pass the signal through to a device that is capable, ensuring that the full Dolby Atmos experience is maintained.
What Devices Support Dolby Atmos Passthrough?
A growing number of devices support Dolby Atmos Passthrough, including TVs, soundbars, and home theater systems. Many of the latest 4K TVs from major manufacturers, such as Samsung, LG, and Sony, support Dolby Atmos Passthrough. Additionally, some soundbars and home theater systems from brands like Sonos, Denon, and Yamaha also support this feature.
It’s worth noting that not all devices that support Dolby Atmos also support Passthrough. Some devices may only support decoding and processing of Dolby Atmos, while others may only support Passthrough. It’s essential to check the specifications of a device before purchase to ensure it meets your needs.
Do I Need A Specific Type Of Speaker System To Use Dolby Atmos Passthrough?
To take full advantage of Dolby Atmos Passthrough, you’ll need a speaker system that is capable of rendering the immersive audio experience. This typically means a speaker system with height channels, such as ceiling-mounted speakers or upward-firing speakers. These speakers are designed to create a truly immersive audio experience, with sound coming from above and around you.
However, if you don’t have a dedicated Dolby Atmos speaker system, you can still use Passthrough with a traditional 5.1 or 7.1 speaker setup. In this case, the Passthrough feature will ensure that the audio signal is still sent to the next device in the chain, where it can be decoded and processed. The immersive audio experience may not be as immersive as with a dedicated Dolby Atmos system, but you’ll still benefit from the enhanced audio quality.
Can I Use Dolby Atmos Passthrough With Any Audio Content?
Dolby Atmos Passthrough is specifically designed to work with Dolby Atmos-encoded audio content, such as 4K UHD Blu-ray discs, streaming services, and some video games. However, if you’re playing back non-Dolby Atmos content, such as stereo or 5.1 surround sound, the Passthrough feature won’t have any effect.
In these cases, the device will simply pass the audio signal through without processing, as there is no Dolby Atmos metadata to preserve. However, if you have a device that supports Passthrough and you’re playing back Dolby Atmos content, you can be sure that the full immersive audio experience will be maintained.
Is Dolby Atmos Passthrough Compatible With Other Immersive Audio Formats?
Dolby Atmos Passthrough is specifically designed for Dolby Atmos content, but it’s worth noting that some devices may also support Passthrough for other immersive audio formats, such as DTS:X or Audyssey MultEQ. However, this will depend on the specific device and its capabilities.
In general, Passthrough is designed to work with the specific immersive audio format that a device supports.
