What is Dolby Atmos Projector?

Dolby Atmos projectors combine high-quality visuals with immersive 3D audio, placing sounds precisely around and above viewers. Used in home theaters, they sync dynamic effects like overhead rain or explosions with on-screen action.

What is Dolby Atmos?

Dolby Atmos is a new audio technology developed by Dolby Laboratories, which breaks the limitations of traditional surround sound channels to create a more natural, realistic, immersive audio experience.

1. Enhanced Accurately-located Sound: The technology abandons the physical speaker limitations of traditional 5.1/7.1 channels and uses object-based audio processing to enable each individual sound source (e.g., helicopter rotor blades, cracking glass in the movie scenes) to be accurately located in a three-dimensional coordinate system, including horizontal orientation, vertical height, and depth distance.

2. 360° Audio for Great Immersion of Movie Watching: Dolby Atmos 360° soundstage package breaks free from the flat, directional sound of conventional setups. Sound objects dynamically track the movement of the screen, for example, when a bullet is fired from the left rear and bounces off the front top, the sound image matches the spatial logic of the movement in real-time.

What Are 5.1 and 7.1 Channels in Surround Sound Systems?

Traditional surround sound systems are mainly based on fixed channel layouts, such as 5.1 channels (Left, center, right, left surround, right surround, subwoofer) or 7.1 channels (Adding left and right rear surrounds on top of 5.1 channels).

The positioning and movement of the sound are mainly dependent on the combination of these channels.

Why Choose Projectors that Support Dolby Atmos?

1. They Provide Strong Sense of Immersion

The most significant effect of Dolby Atmos is the unprecedented immersion for the audience. When watching movies, TV shows, or playing games, the sound surrounds the viewer from all sides, including above the head.

The audience can clearly feel raindrops falling from the sky and airplanes flying over their heads. This immersive feeling allows us to fully integrate into the content, greatly enhancing the experience of watching movies or games.

For example, when watching the battle scene of the spaceship in a science fiction movie, a 4k Dolby Atmos projector allows the audience to clearly hear the roar of the ship's engine, the sound of the weapon launching, and the shockwave generated by the explosion as if they were in the vast universe of the battlefield.

2. Dolby Atmos Projectors Deliver Rich Sound Details in Movies and Music

Dolby Atmos is able to show extremely rich sound details, enabling the audience to hear the sound that was easily ignored in the ordinary audio system.

In the movie, the character's subtle action sound, such as clothing friction sound, footsteps, etc., can be clearly audible.

In the music performance, the timbre and performance details of various musical instruments can be more realistically reproduced.

This precise presentation of sound details allows the audience to better understand and feel the emotions and atmosphere conveyed by the content.

3. This Kind of Audio Technology Has Enhanced Dynamic Range

Dolby Atmos has a wider dynamic range, which can realize the natural transition from very faint sound to impactful loud sound without losing sound quality.

In the quiet scenes of the movie, such as late-night forests, the library's silent atmosphere, etc., Dolby Atmos can present a very subtle ambient sound, so that the audience can feel that peaceful atmosphere.

In the intense action scenes, such as explosions, wars, etc., Dolby Atmos is able to erupt with a powerful volume, giving the audience a shocking auditory impact.

AURA 2 XGIMI Dolby Atmos projector 4K Laser is designed for home movie theater, gaming, music playing, and others.

This powerful dynamic range processing capability makes the plot of the movie more gripping and the music more expressive.

Dolby Atmos revolutionizes the audio experience for projection by creating an immersive, detail-rich sound environment with powerful dynamic range through unique audio technology and strict certification conditions.

At XGIMI, you can choose AURA 2 with Dolby Atmos support to enjoy a top-notch audiovisual feast comparable to a movie theater at home.
