4K Arcana 18GBPS

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.

I bought a Sonos Arc 2 for my 5+ year old Samsung TV (UN49M5300AF) and a Amazon Fire TV Cube (3rd Gen) to improve the sound for my TV setup. The TV only has an ARC port (no eARC) and only supports Dolby Digital Plus, so in principle I should have been able to get Dolby Atmos (compressed), which I would have been happy with. However, it turns out that Amazon Prime and Netflix only deliver Dolby Atmos sound to 4k TVs (WTF Amazon and Netflix?!), so I was never getting Dobly Atmos sound because the TV is only 1080p. I had no interest in buying a new TV because getting rid of the current TV seemed like a waste of a perfectly serviceable TV. The Arcana solves this problem beautifully. The Arcana allows me to tell the Fire TV Cube that the Cube is talking to a 4k TV. This unlocks Dolby Atmos sound from Amazon and Netflix. The Arcana also downscales the 4k picture stream for the 1080p TV. In addition, the Arcana solves lip syncing issues. Before adding the Arcana, I could never get perfect lip sync. I tried all adjustments possible (the Fire TV Cube, TV, Sonos), but I had to adjust for shows/movies that had different audio standards (PCM 2.0, Dolby Digital, Dolby Digital Plus). The only somewhat reliable way to solve the lip sync issue was to match the TV sound standard to the source standard (where possible). Doing this for every show was obviously a pain, and meant that I wasn't able to get the full performance of the Sonos Arc 2 sound system. With the Arcana, I have none of these problems. I get the highest quality sound with no lip sync issues. I did have to change some of the default settings on the Arcana to get the setup to work. From memory, I changed the following settings from the default values: * Audio: eARC only * Scaler: 4K30 422 12b SDR * HDR: Force 1000 nits The firmware version on the Arcana is 0.87. Many older reviews (and a friend of mine) say they have problems with the Arcana and connected devices having to be turned on in a particular order. I have not had this problem with my setup. I suspect that HDFury has solved many of these problems in later firmware versions. The manual for the Arcana is very technical and one can tell it is written by somebody whose native language is not English. You should read the manual (which is available online) very carefully to make sure that the Arcana is a device that will support your use case. This device is not what I'd call a plug and play device like most consumer devices. In my opinion, you need to be willing to read the manual, maybe look up some technical terms and acronyms, and play around with the settings. In short, this is a technical box that requires a user that is interested in going beyond just plugging it in and hoping it will work. I'm super happy with this little box and can highly recommend it for a setup like this (if you're willing to put the time in to configure it for your set up).

I tried to like it but it was way more bother than it was worth. Read many reviews that said basically the same but thought I would take a chance. It was utterly disappointing. When it worked with my Sonos home theater system, which was rare, it sounded great and picture quality was good. The problem was it would randomly drop picture or sound or both and I would have to reboot everything to get it to function again. And using an hdmi switcher for blu ray, PS and Firestick was a nightmare. If you tried to switch from one source to another the Arcana would have to be rebooted every time. Very aggravating. So I sent it back until a more viable alternative becomes available. For now I’ll use the optical output from the projector sacrificing Dolby Atmos but at least it works flawlessly so we can enjoy a show or movie without all the hassle.

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 !

Strepitoso!!! L’ho usato per poter connettere xbox series x(ed avere dolby atmos senza ritardo audio) a la Sonos Arc ( tramite earc), è funziona da Dio!! , segnale video perfetto e audio senza perdita in dolby atmos direttamente dalla soundbar. Ti fa risparmiare i soldi per un nuovo tv da 1000 euro con hdmi Earc. Vale i soldi che costa perchè e l’unico accessorio che trasforma le hdmi normali in Hdmi earc. Incredibile!

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!

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.
