You get the best surround sound with Dolby Atmos. In addition to the well-known 5.1 or 7.1 channels, elevation channels are also added, resulting in a 5.1.2 system, for example. We’ll show you that this effect is also possible with soundbars that combine several speakers in one form. This is how you bring the cinema experience home to you!
How is Dolby Atmos possible with a sound bar?
The fact that this multitude of different channels and thus directions comes from only one sound bar is made possible by reflection from the ceiling and walls. However, the Atmos effect becomes even better when rear speakers are included.
Dolby Atmos is one of the new object-based surround sound formats. It does not store audio tracks for several clearly defined channels (e.g. 5.1 channels), but audio tracks for objects in the room, which are then played back by different loudspeakers depending on the set-up.
Even though in theory Dolby Atmos can be used for many more channels, the Dolby TrueHD codec, which is the most widely used nowadays, can handle anything up to 9.1.6.
For a soundbar, however, this is at most conditionally possible. Even if high-end sound bars use the walls and ceiling to reflect the sound, 5.1.2 or rarely 7.1.2 is the end of the line. This results in a noticeably better surround sound that can’t be compared to a real Dolby Atmos surround system.
LG throws a top product into the ring with the SL10Y. The wireless subwoofer and sound bar provide 5.1.2 Dolby Atmos sound.
The sound bar can be connected via 3.5mm jack, HDMI, LAN, Bluetooth and WLAN. So it should fit into every home cinema setup.
Operation is even easier – either by remote control or by voice control from the comfort of the couch.

Of course Sony also offers a Dolby Atmos sound bar. The HT-ST5000 produces virtual 7.1 surround sound using the built-in S-Master HX digital amplifier, a wireless subwoofer and seven speakers.
The surround sound is fantastic, which is confirmed by numerous customer voices.

Do I need HDMI eARC?
Not really. If Dolby Atmos is stored in the Dolby Digital Plus codec (which streaming services like Netflix & Amazon Prime use), then “normal” HDMI ARC is sufficient to send the Atmos sound back to the sound bar.
HDMI eARC returns Dolby Digital to a sound bar in the Dolby TrueHD codec. The Dolby TrueHD codec is actually only used with Blu-ray Discs. Depending on how you play these discs, you often have the possibility to separate picture and sound at the player, which makes an audio return channel between TV and sound bar obsolete.
However, it should be mentioned that Dolby Digital Plus is more compressed than Dolby TrueHD and that streaming services may switch to the other format in the future.
