Vizio's mid-range 5.1.2 system pairs a soundbar with motorised height speakers that physically rotate up for Dolby Atmos and forward for music or dialogue, plus a wireless subwoofer and two wired rear satellites. The bar offers HDMI 2.0b — one input and one eARC output — with 4K HDR and Dolby Vision passthrough on the input and Atmos/DTS:X over eARC on the output. Optical TOSLINK and a 3.5mm AUX (for the included voice-assistant cable) round out the inputs; the rear USB-A port is firmware/service only and does not play media. Power uses a 2-prong figure-8 IEC C7 inlet rather than a 3-pin C14.

Notes & Compatibility
All HDMI ports are HDMI 2.0b. HDMI input supports 4K HDR + Dolby Vision passthrough; HDMI OUT carries Atmos/DTS:X via eARC (no 4K@120Hz / VRR — the bar predates HDMI 2.1). Rear USB-A is for service / firmware updates only — does NOT play media. 3.5mm AUX is dedicated to the included voice-assistant input cable. Bar uses a 2-prong figure-8 IEC C7 mains inlet (represented as IEC C8 Figure-8 Inlet to match Cablebabe convention). Year corrected from 2023 to 2022 during research (Vizio model page lists 2022 release). Wireless subwoofer and two wired rear satellites included; their connectors are internal to the system.
