HDfury Arcana 2 - 8K eARC Adapter & Audio Extractor
The HDfury Arcana 2 is the HDMI 2.1 evolution of the world's first eARC adapter: full lossless audio — up to Dolby Atmos over TrueHD and DTS:X — from any HDMI source to any eARC, ARC or HDMI sound system, now with 40Gbps bandwidth for 4K120 VRR gaming and 8K video. Built for PS5, Xbox Series X and gaming PCs paired with soundbars like the Sonos Arc or any AV receiver.
Full audio and full bandwidth — no compromises
TVs are the bottleneck in most setups twice over: their ARC connection strips lossless audio, and many can't pass 4K120 VRR through to a soundbar chain at all. The Arcana 2 solves both. Video runs straight to your TV, monitor or projector at up to 4K120 4:4:4 10-bit with VRR, while the full untouched audio goes to your sound system over eARC — with less than 1 ms of added lag.
Key features
- HDMI 2.1 FRL5 — 40Gbps — 4K120 4:4:4/RGB 10-bit with VRR and HDR, up to 8K60 (DSC); supports VRR, ALLM, QMS and QFT.
- Full audio to any sound system — Dolby Atmos (TrueHD and MAT), Dolby TrueHD, DTS:X, DTS-HD Master Audio and every legacy format, over eARC or ARC.
- Three outputs — main HDMI out, eARC audio out, plus the unique HDMI COPY output: feed a second display, a downscaled signal for accessories like Philips Hue Sync, or HDMI audio to an older (non-eARC) AV receiver.
- Every HDR format — HDR10, HDR10+, HLG, Dolby Vision and LLDV, with real-time HDR metadata adjustment.
- LLDV for projectors — play Dolby Vision content on HDR10 displays and projectors, with the source doing the DV tone-mapping.
- Lip-sync fixed for good — adjustable audio delay from 0 to 255 ms.
- OLED status display — see live exactly which video and audio format is passing through.
- Installer friendly — RS-232 control, CEC volume control, EDID management, upscale/downscale options and USB firmware updates.
What the Arcana 2 is most used for
- 4K120 VRR gaming with full Atmos — PS5, Xbox Series X or gaming PC to a 120Hz display, with lossless audio to your soundbar or AVR.
- Sonos Arc and modern soundbars — true Dolby Atmos over TrueHD from any source, instead of the lossy version your TV forwards.
- Feeding two displays — TV plus projector, or a main screen plus a downscaled copy, via the HDMI COPY output.
- Older AV receivers — send HDMI audio to a non-eARC receiver from the COPY output while your display gets the full 40Gbps signal.
- Dolby Vision on HDR10 projectors — the built-in LLDV solution unlocks DV playback on displays without native support.
Arcana 2 or the original Arcana?
Both deliver the same core promise: full lossless audio to your sound system. The difference is video bandwidth and outputs:
| Arcana 2 | Arcana | |
| Max video | 4K120 4:4:4 / 8K60 DSC (40Gbps, HDMI 2.1) | 4K60 4:4:4 (18Gbps, HDMI 2.0b) |
| VRR / ALLM gaming | Full 4K120 VRR, QMS, QFT | 1080p120 / 1440p120 |
| HDMI outputs | 2 + eARC out | 1 + eARC out |
| Ideal for | PS5 / Xbox Series X / PC at 4K120 VRR, 8K, dual displays | Apple TV, Blu-ray, streaming, 4K60 gaming |
In short: gaming at 4K120 VRR, HDMI 2.1 sources or a second display → Arcana 2. Streaming boxes, Blu-ray and 4K60 → the original Arcana does the same audio job for less. Still not sure? See the full Arcana vs Arcana 2 comparison.

Frequently asked questions
Can I game at 4K120 with VRR through the Arcana 2?
Yes — that is exactly what it's built for. The full HDMI 2.1 FRL5 bandwidth (40Gbps) passes 4K120 4:4:4/RGB 10-bit with VRR, ALLM, QMS and QFT, adding less than 1 ms of lag.
Does it give my Sonos Arc full Dolby Atmos?
Yes. Your TV's ARC connection strips Atmos down to lossy Dolby Digital Plus; the Arcana 2 feeds your Sonos Arc lossless Dolby Atmos over TrueHD directly from the source.
What is the HDMI COPY output for?
It's a second, fully manageable HDMI output. Use it for a second display, a downscaled signal (for example for Philips Hue Sync), or to send HDMI audio to an older AV receiver without eARC.
Does the Arcana 2 support 8K?
Yes — up to 8K30 4:4:4 and 8K60 with DSC over its 40Gbps HDMI 2.1 bandwidth.
What's the difference with the original Arcana?
The audio capabilities are identical. The Arcana 2 adds HDMI 2.1 bandwidth (4K120 VRR, 8K) and a second HDMI output. For streaming and 4K60 setups, the original Arcana does the same job for less.
Can it fix lip-sync problems?
Yes — the audio delay is adjustable from 0 to 255 ms, so you can dial audio and video perfectly into sync.
