8K HDMI 2.1 eARC Audio to Soundbar Adapter
De-embed ARC/eARC Audio to Any Soundbar — HDMI 2.1 Video Passes Through at Full 48Gbps
Bridges the gap between HDMI 2.1 eARC displays and soundbars lacking native eARC support by de-embedding ARC/eARC audio from any 8K-capable TV or HDMI source and routing it via HDMI to the soundbar — including SONOS ARC, SONOS Beam, and any eARC soundbar. HDMI 2.1 and HDCP 2.3 compliant at 48Gbps FRL with zero video and audio latency.
Designed for CEDIA integrators specifying retrofit and new-build installations, the AUD-SBAR-8K handles 8K@60Hz and 4K@120Hz with full HDR pass-through (HDR10, HDR10+, Dolby Vision, HLG) and HDMI 2.1 protocols including VRR, ALLM, QMS, QFT, and SBTM. Eight DIP-switch EDID modes and a USB-C firmware update port ensure long-term field serviceability.
