These boxes will send Dolby Atmos through your home's power lines
Briefly

Fasetto's Audio Cu, which just received Dolby Atmos Product Certification, leverages existing power line wiring to connect audio devices and speakers without the clutter of cables.
The Audio Cu system offers a latency of less than 20 milliseconds, ensuring a reliable audio signal while being unaffected by typical wireless interferences.
The user-friendly setup allows for audio presets and adjustments through an app, while controlling volume is as simple as using a TV or projector remote.
By accommodating systems up to 7.1.2 Dolby Atmos with compatibility for existing speakers, Audio Cu revolutionizes home audio setups by simplifying installation.
