HDfury Arcana 2
HDfury Arcana 2 combines HDMI 2.1 FRL5 video up to 40Gbps with full HDMI audio extraction. Use it for 4K120/VRR consoles, gaming PCs, 8K signals, Sonos Arc or Beam 2, modern eARC systems, older receivers, and a second video or audio output.
Product description
What does HDfury Arcana 2 do?
Arcana 2 sits between your HDMI source and display. Video goes to the TV, monitor, or projector, while full HDMI audio can be sent separately to an eARC, ARC, or HDMI audio system. The additional HDMI COPY output can mirror, scale, or operate as a full HDMI audio output.
Output full audio separately
Send audio up to Dolby Atmos/TrueHD, Dolby MAT Atmos, DTS:X, and DTS-HD Master Audio directly to a compatible eARC, ARC, or HDMI audio system, without the display limiting the source’s audio capabilities.
HDMI COPY output
Use the second HDMI output as a mirror, a scaled output for a second display, Hue Sync or capture device, or as a 1080p HDMI audio stream for an older receiver.
Signal management
Manage EDID, HDCP, resolution, chroma, color space, and color depth. Arcana 2 can upscale or downscale depending on the signal and displays live signal information through OLED and OSD.
Adjustable lip-sync delay
HDFURY ARCANA 2 provides an adjustable eARC audio delay from 0 to 255 ms. This lets you precisely delay audio that leads the video. According to the manual, the video path itself adds only a few pixel clocks of processing.

Getting started
Step-by-step connection
Follow this order. It prevents multiple cables, devices, or settings from becoming possible causes at the same time.
1. Check the source, display, and cables
For 4K120, 8K, or VRR, both source and display must support HDMI 2.1 FRL. Use cables between source, Arcana 2, and display that can handle the required bandwidth. The cable to an eARC soundbar only needs reliable ARC/eARC support.
2. Connect the HDMI source
Connect the HDMI output of your console, media player, PC, Blu-ray player, receiver, or HDMI switch to HDMI IN on Arcana 2.
3. Connect the main display
Connect HDMI OUT on Arcana 2 to the correct HDMI input on your TV, monitor, or projector. Use the TV’s ARC/eARC input when you also want to return TV audio.
4. Connect the audio system
Connect eARC OUT to Sonos Arc, Beam 2, or another compatible ARC/eARC system. For a receiver with a regular HDMI input, HDMI COPY can be configured as the audio output.
5. Use HDMI COPY only when needed
Connect a second display, Hue Sync, capture card, or older receiver here. Then select the appropriate mode in the menu: mirror/pass-through, downscale, or full HDMI audio.
6. Power on and check the OLED
Power on the display and audio system first, then the source. Check the OLED to confirm that input, resolution, frame rate, HDR/VRR, and audio are detected correctly.
7. Change only targeted settings
Start with the default settings. Change EDID, scaling, LLDV, HDR metadata, or CEC only when the connected equipment requires it. Record changes so you can easily revert during troubleshooting.
Getting Started with connection diagrams
Choose the diagram that matches your equipment. Follow the cable routes before changing Arcana settings.
One source + eARC
Connect one HDMI 2.1 source to Arcana 2, send the main video output to the display and full audio to the eARC sound system. HDMI COPY can feed a second display, Hue Sync, capture device or older AVR.
Multiple sources + eARC
Connect the sources to an HDMI 2.1 switch or receiver, connect its output to Arcana 2, and route video, copy output and eARC audio separately.
Common setups
One source + eARC soundbar
Source → Arcana 2 HDMI IN. HDMI OUT → TV/projector/monitor. eARC OUT → Sonos Arc, Beam 2, or another eARC system. This sends full audio from the external source directly to the audio system.
Multiple sources
Connect sources to a suitable HDMI 2.1 switch or receiver and connect its output to Arcana 2 HDMI IN. The switch/receiver must genuinely support the required 40Gbps, FRL, and VRR signals.
Return TV audio
Connect HDMI OUT to the TV’s ARC/eARC port. Arcana 2 can then send both audio from the external source and ARC/eARC audio from the TV to the connected audio system.
Second display, Hue Sync, or older AVR
Use HDMI COPY for a second video output, a scaled TMDS output, or a 1080p stream with full HDMI audio for an older receiver. The correct COPY mode depends on the connected device.
Important: an HDMI chain is only as strong as its weakest link. The source, cables, switch/receiver, Arcana, and display must all support the required video and audio format.

Frequently asked questions
The answers below clarify the most common misunderstandings before installation or purchase.
Does HDFURY ARCANA 2 turn my ARC TV into an eARC TV?
No. The TV’s ARC port does not become eARC. Arcana 2 extracts full audio directly from an external HDMI source and sends it to a compatible audio system. TV apps remain limited to what the TV can return through ARC/eARC.
Do 4K120 and VRR always work?
Only when the source, display, cables, and any intermediate equipment support the required HDMI 2.1 FRL bandwidth and the relevant VRR format. Basic FreeSync/G-Sync outside HDMI 2.1 FRL cannot automatically pass through every intermediate device.
Which cables do I need?
Signals up to 40Gbps require suitable Ultra High Speed HDMI cables between source, Arcana 2, and display. Keep copper cables short where possible; for longer runs, use a quality active or fiber-optic cable. A reliable ARC/eARC cable is sufficient for an eARC soundbar.
Can I use Sonos Arc or Beam 2 without an eARC TV?
Yes, for external HDMI sources. Arcana 2 creates a suitable eARC audio output for the soundbar while video goes to the TV, projector, or monitor.
Can HDMI COPY connect to an older receiver?
Yes. HDMI COPY can be configured as a full HDMI audio output with a video signal an older receiver can accept, such as 1080p. The receiver itself must support the required audio formats.
Does HDFURY ARCANA 2 support Dolby Vision and LLDV?
Yes. Arcana 2 supports Dolby Vision and LLDV with compatible source and display combinations and can advertise an optional LLDV data block through EDID. This does not turn an HDR10 display into a native Dolby Vision display.
Lost HDFURY ARCANA 2 lipsyncproblemen op?
HDFURY ARCANA 2 extracts audio directly from the external HDMI source, often bypassing delay caused by decoding or re-encoding in the TV. When audio leads the picture, enable delay in the eARC menu and set a value from 0 to 255 ms. Start low and increase it gradually. The device cannot move audio forward when it already arrives too late; in that case, check the source, TV, and soundbar settings. Apple TV users can also use Wireless Audio Sync.
Should I change EDID or scaling immediately?
No. Start with the default settings. Change EDID or scaling only when a device detects the wrong video or audio capabilities, a second output requires a lower resolution, or a specific LLDV/HDR configuration is needed.
