A four-speaker wireless home theater system (successor to the HT-A9) whose wired connections all live on a compact control box. That box offers one full-bandwidth HDMI 2.1 passthrough input with 4K@120Hz, 8K, Dolby Vision and VRR support — effectively giving your TV back a gaming port — plus an eARC output and wired Ethernet. There is no optical input and no USB port, so a TV with eARC/ARC is required. A 3.5mm S-Center Out can hand center-channel duty to a compatible Bravia TV.

Notes & Compatibility
All wired I/O is on the control box; the four speakers connect wirelessly. HDMI input passes 4K@120Hz, 8K@60Hz, Dolby Vision and VRR. No optical input and no USB — the TV must support HDMI eARC/ARC. Powered by an external 12V adapter (proprietary DC connector, not modeled). S-Center Out requires a compatible Sony Bravia TV. Optional wireless subwoofers (SA-SW3/SW5). Sony’s own specification page lists the control box’s HDMI sockets as “HDMI IN and HDMI OUT (eARC/ARC)” and states HDMI 2.1 capability for 8K HDR passthrough, which confirms the full-bandwidth feature set on the pair. With no optical and no USB alongside them, those two sockets are the entire wired surface: everything that is not plugged into the passthrough has to come back over the TV’s eARC link, so the TV’s eARC implementation decides whether lossless Atmos ever reaches these speakers.
