HDFury 4K Arcana 18GBPS

I purchased the HD fury Arcana for one reason - to enable my Sonos Arc to play downmoxed DTS from my Panasonic 820 4k player and display on my LG G1 tv. This is quite an expensive solution, however I was getting very frustrated with my DTS audio 4k discs only playing in 2.0 stereo on the Sonos as LG tvs no longer allow DTS pass through. While the Sonos won’t support full DTS master audio, it will at least downmix it to standard DTS which is better than 2.0. I can also confirm that when using an ears or arc capable tv, the tv ARC will still send down mixed audio to the arcana and through to Sonos. In order to get the best benefit, I have used a UGreen 8k 5 port hdmi switch to connect my 4k blu ray player and Apple TV to the arcana. Which means I can now get the full audio through to the Sonos. I have so far not experienced any lip sync or drop out issues. I also have a ps5, but have this connected to the tv direct and the arc allows surround 5.1 to be passed through the arcana to the Sonos. This is because the arcana will not support VRR (I believe the Arcana 2 will). I can live with standard 5.1 for gaming! Picture quality to rough out is exceptional and I can’t notice any difference. I had to fiddle with settings a bit to ensure Dolby Vision displayed properly. Also worth noting - my G1 has 3 usb outputs. I use only one as the power for the arcana. This currently seems to work and also means the arcana will power cycle with the tv I believe. Be aware that usb puts on tvs are generally underpowered, so I don’t plug any thing else in the spareness to ensure all power routes to the arcana. Failing this solution, the arcana does come with a usb power plug if required. This isn’t the solution for most people I’m sure, and certainly not cheap, but for me it works well.

I have used a hdfury vertex in the past before Sonos finally added support for DTS to the playbar, it was necessary to use the vertex with my Sony TV otherwise I would get silence when playing something with a DTS audio track. I have a Philips Picomax projector, and in order to get sound to my Sonos beams, I have to use a dummy audio cable to silence the internal speaker on the projector, and I then use the arcana in “beam” mode which is fed from a NVIDIA shield, the HDMI output goes to the projector and the ARC output from the arcana goes to the beam, the arcana presents itself as a ARC “TV” and the beam then plays the audio! Perfect! No problems for my gen 1 beam. One thing you must do is that if you change audio settings on your source, then you should cycle the audio on all the parts of the system (in my case I restart the shield and the beam) so that everybody gets to negotiate what sound formats are available, if I change any audio settings on the shield I restart both thr shield and the beam EVERY TIME. If you don’t do this, you might start fiddling with audio and then find that you’re getting stereo PCM output when playing something you know everything in thr chain can play correctly. Been there, got the t shirt many times over, so now I just restart everything and I don’t have any issues. The arcana is working absolutely spot on for me, I can’t comment on its eARC abilities since I don’t have eARC, but its ability to appear as an ARC TV to the beam now means I get great sound on the projector. It’s not a cheap device (although much cheaper than the other vertex) but without it my sound options are much more limited since I then have to use optical audio which severely limits the supported formats. If you’re looking to use this with a Sonos beam, I can recommended it.

It's OK, but it can give you some problems

Finally a way to get dolby atmos back from my fire cube3 to sound bar after it stoped. Now have full atmos and video is brighter and more colourful a very worth wile product that dose what it says and so simple to use.

Was advised that this product would enable me to split the audio signal to a SONOS ARC soundbar and the video to a 4k projector. For a start some detailed instructions in understandable English might help. The information on the display is of no help. Most importantly it doesn't give a stable consistent output to either the Soundbar or the projector. Will try a bit longer to get it to work but currently thinking is that it will be returned as not fit for purpose.

Sent mine back, thought I’d save on getting a new TV but you’re probably better off putting the money towards a new TV which is what I had to do as this is a pain and certainly not worth over £200

Plug and play solution for Sonos Arc lipsync issues.

Merci aux personnes qui ont créés ce produit ! Mon installation est la suivante : TV LG 55UJ634V, 4k, HDR avec port ARC mais pas de eArc (TV de 2017) Apple TV 4k branchée sur une Hdmi SyncBox. Et la Sonos Arc pour le son. Le HD Fury arcana vient parfaire cette installation, je l'ai branché entre la sortie de la Syncbox (qui fait office de switcher Hdmi) et la TV. Après quelques (pas mal en réalité) réglages et le changement des mes câbles Hdmi qui ne supportaient pas le flux (coupures intempestives de l'images pendant quelques secondes). J'arrive enfin à une installation stable ! Le produit est assez simple, léger, une interface en anglais (uniquement), il fait son job à la perfection ! Et projette un message de log sur le bas de l'écran TV super pratique pour visualiser les caractéristiques des flux qui passent par le boitier. (Ce message est désactivable via les réglages). Je recommande ce produit ! Bien que le prix, pique un peu !

I got this HDFury Arcana to send Dolby Atmos to a Sonos Arc from an UHD Player and an Apple TV. My TV (Vizio PX65-G1) wasn’t sending an Atmos signal to the Arc, and after some research, I found that it didn’t have enough eARC support. This little device solved that. It was relatively simple to set up, and after some tinkering (thanks youtube) it’s now working perfectly, without the blue info text on the screen. Can confirm it supports 4K HDR Dolby Vision and Atmos. It’s fantastic. Vision and Atmos films play perfectly through it, and it lets me take full advantage of the Sonos Arc and Era 100s. The only issue is it has only one input. That’s easily solved with a switcher, so I picked up a UGreen HDMI 2.1 8K switcher to go with it. Pairing the switcher with this HDFury has enabled me to enjoy full Dolby Atmos without the need to purchase a new eARC TV. I wholeheartedly recommend this for that upgrade. I dedicated considerable time researching the reasons behind my inability to access Atmos through my existing setup. If you are trying to resolve a similar issue, I hope this review saves you that time!

Allowed me to eventually connect my Sonos Arc over HDMI. Got rid of all my SPDIF cables and hub. I use it together with the HDFury Vertex2, great buy too. Bit tricky to setup maybe, firmware update and all but works great. Definitely the best tech money can buy when it comes to Home Theatre and HDMI setup. Support is also fantastic, just go on the Discord channel you will get help anytime of the day or night.

If you’re using a projector, Apple TV 4K, and Sonos soundbar, the Arcana HDFury 4k does solve the audio problems — but only if you configure it correctly. Out of the box defaults will cause black screens, missing movie audio, or broken volume control. Use my settings below and it becomes rock solid. My setup • Source: Apple TV 4K • Display: Epson 3800 projector (HDR10, no Dolby Vision) • Audio: Sonos Beam (Gen 1) + surrounds • Cable run: Long HDMI to ceiling-mounted projector • Use case: Movies and TV only (no gaming) Before Arcana: • Audio dropouts • No volume control • Black screens when starting or exiting movies • SPDIF hacks required • Constant HDMI re-syncs After Arcana (configured correctly): • Stable picture • Proper Dolby Digital 5.1 in movies • Menu audio works • Volume control works • No black screens • No SPDIF needed Important reality check (projector owners read this) Projectors do not handle SDR ↔ HDR switching well. If you let Apple TV auto-switch formats, you will get black screens. This is not an Arcana problem. The fix is to lock the signal. Arcana settings (critical) These are the settings that actually matter. On the Arcana: • Add PCM 8ch: ❌ OFF (This is crucial. If ON, movie audio will fail on Sonos.) • Add DTS:X / DTS-HD: ❌ OFF (Sonos doesn’t support DTS.) • TV ARC Routing: ❌ OFF • eARC Only: ✅ ON • Unmute Delay: OFF • TV Standby Mute: OFF Do not force formats. Let Arcana present a clean EDID. Apple TV settings (projector-safe, stable) This is the key to avoiding black screens. Video • Format: ✅ 4K HDR • Match Dynamic Range: ❌ OFF • Match Frame Rate: ❌ OFF • Chroma: 4:2:2 Yes, this means menus are in HDR. No, you’re not losing anything on a projector. Yes, it stops HDMI resyncs. Audio • Audio Format: Auto • Default Audio Output: Receiver (TV) (Correct even though you’re using Sonos.) Remotes & Devices • Control TVs and Receivers: ON • Volume Control: Auto via HDMI Do not default to AirPlay for TV audio. What “working correctly” looks like This is how you know it’s right: • Menus: PCM stereo (normal) • Movies: Dolby Digital 5.1 (check Sonos app → About My System) • Volume: Controlled by Apple TV remote • Picture: Always HDR, no black screens on pause or exit • Projector Info screen: Shows HDR10 (not Dolby Vision) Apple TV may say Dolby Vision is enabled — that’s fine. The Epson ignores it and displays HDR10. CEC expectations (don’t fight this) - Projector will usually turn off via HDMI - Projector will usually not turn on via HDMI - This is normal for Epson projectors Use the projector remote or a universal remote for power-on. Bottom line The Arcana 4K absolutely works for projector + Sonos setups, but: You must disable PCM 8ch and lock Apple TV to 4K HDR. Once configured: - No SPDIF hacks - No audio dropouts - No black screens - No guessing Once setup, unplug everything, wait a full minute, 60 seconds. Then plug in turn on the projector and Sonos so they are fully booted up. Then plug in and turn on the arcana and let it negotiate with both devices. Then plug in and turn on the Apple TV. Seriously, the timing and order matters! Take your time, it’s worth it. This setup is now boring — and that’s the highest compliment I can give it.
