Dolby Labs has a new home theater technology called Dolby Atmos FlexConnect. The company says it will let people with a compatible TV placewireless speakersanywhere that’s convenient, and the TV’s built-in microphones will automatically calibrate them to work with the TV’s speakers while ensuring the whole setup produces optimal sound. The technology will make its debut in the2024 TCL X955 QD mini-LED 4K TV, but Dolby anticipates that other companies will also announce support for Dolby Atmos FlexConnect.
Because Dolby Atmos FlexConnect works wirelessly and uses a compatible TV’s built-in hardware and software, you’ll be able to set up aDolby Atmosaudio system that doesn’t require asoundbarorAV receiveras its central unit and doesn’t need anHDMI cableto send an audio signal to an external device.
Dolby’s tech is separate from a TV’s operating system — so we could see Dolby Atmos FlexConnect on TVs from any number of TV makers whether they use Google TV, Roku, or any othersmart TVsoftware, but it does require that the TV use the latest Dolby multi-stream decoder.
UnlikeSonos, or technology platforms likeDTS Play-FiorWiSA, which rely on a combination of compatible software and hardware linked to each other using Wi-Fi, Dolby Atmos FlexConnect is connection and hardware-agnostic. Dolby is leaving decisions around the types of speakers and the wireless technology to the TV manufacturer, so if TCL (for instance) could figure out a way to link multiple wireless speakers using Bluetooth, that would be just as compatible with Dolby Atmos FlexConnect as Wi-Fi, or a proprietary wireless system.
There’s no hard limit to the number of wireless speakers or channels that Dolby Atmos FlexConnect can support, but it’s likely that TV makers will each have their own specific limitations based on the processing capabilities of their internal hardware. In theory, you could use a wireless speaker as the center channel, or simply rely on your TV’s speakers to shoulder that task.
I asked Dolby Labs if we can expect to see wireless speakers and/or subwoofers that promise Dolby Atmos FlexConnect compatibility, but apparently, that’s not really a thing. It will be up to each TV maker to decide which wireless speakers it wants to support and, presumably, some companies will choose to only support the wireless speakers that they make.
Dolby highlighted the following four benefits of Dolby Atmos FlexConnect:
ManyDolby Atmos soundbarsfrom companies like Sony, LG, Samsung, Sennheiser, Bose, and Sonos have microphone-based calibration systems that perform a similar task to Dolby Atmos FlexConnect, but they’re generally much more strict about the number of speakers that can be used. Some, like Sony (Bravia Acoustic Center Sync), LG (Wow Orchestra), and Samsung (Q Symphony), can integrate with a TV’s built-in speakers, but it only works with select TV models from the same company. Some of Samsung’s soundbars can also connect wirelessly to the company’s TVs.
More details about TCL’s implementation of Dolby Atmos FlexConnect will be available when the company broadcasts its2023 global flagship product launchat 2 p.m. CEST (8 a.m. ET/5 a.m. PT) on August 29 on YouTube.
