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.

The Arcana is a well designed piece of specialist equipment for receiving an eARC compatible HDMI signal and then routing it to an eARC compatible sound bar or receiver. This allows you to bypass an older TV ARC input which will not route uncompressed Dolby Atmos or DTS:X channels to Atmos or DTS:X compatible equipment. Arcana does not modify the sound signal at all but it is possible to change scaler settings, in case your display has issues with Dolby Vision, HDR or chroma settings. This is a great feature to have control of and in addition, the built-in OLED display will show what is being input and output, assisting with various HDMI or display issues. The big caveat with this device is that many commonly installed cables will not work with it. Technical support for HDFury is not industry-standard. They rely on a Discord channel which is like a public chat room, where your technical issues can be answered by anyone although there are a few dedicated tech support reps on there. It does tend to make for a very loose and occasionally critical tech support experience though, so be warned. They tend to have their recommended cables and then the ones they absolutely detest and unfortunately, my cables fell into the latter category. As the cables are recently wall-installed, they are going to stay for now (my other equipment is fine with them). I would recommend checking the Discord channel before you buy, to make sure you are ready with the recommended cables. Although it could be viewed as a convenient excuse, from looking back at the Discord archive for this device, many users found that when they switched to the recommended cables, they had a much better experience and the device did what it was designed for. I like the product but as it will not work for me without some major structural change, it will be returned. It did produce a solid Atmos signal to my sound bar but due to what was likely cable issues, when the Arcana was in the mix, I often did not get the highest quality video or CEC control via the TV remote. I took a star off because Discord is a bit of an amateurish way of doing tech support but it seems to work for them and should not otherwise detract from a great product.

I bought this to fix sync issues between my LG C1 OLED and Sonos Arc. It was a last ditch effort that I was sure wouldn't work since nothing was fixing the problem (for those with the same equipment and issue, the only thing that will fix the problem is tinkering with audio delay from one TV show or movie to the next. There is no single solution). The 4K Arcana, to my surprise and relief, actually solved the problem. More than that, the audio is noticeably improved, so I'm additionally grateful for that. There are no overall issues with the Arcana. It is expensive and honestly shouldn't need to exist given the simplicity of the issue it's designed to fix, but the issue exists and it does fix it, so it's worth its cost. The user interface is a little intimidating at first because of how primitive it appears ("I paid $300 and this is what they gave me? No way this works"), but it is ultimately an impressive piece of equipment. Another small complaint some might have: using this with an Apple TV sometimes throws off the apple remote so that your TV won't turn off along with the Apple TV. This issue fixed itself for me, but I was willing to keep turning the TV off on its own in exchange for synced sound. Not a dealbreaker in the least.

I have been struggling with this since I received it. when it works it's great. The problem I have is it keep blinking off the screen like it's resetting the video output but it stays the same. I have purchased 5 different HDMI cables to see if it will stop. waiting on the next 2 to come in and try it again. if this continues I will return this item and look for something else that might work. I have emailed customer service for help in the matter and went through the owners manual several times and watched countless YouTube videos trying to see if there is a fix. Nothing working, possible I have a bad unit. Again with the Sonos ARC the sound is perfect it's just the video cutting out that is driving me crazy.

I connected Sonos Arc to my PC using this procust and entire Sonos room system is used as a PC speaker. I set audio device an HDMI which is connected from PC GPU to input of Arcana. Then Arcana is connected to my second monitor and via eArc to Sonos. When I play music via Airplay (iPhone) and say also play video on PC - PC wins cutting iPhone music, but it is also easy to take it back from iPhone. If I dont need to output from PC I set different device as default audio temporarily. As Sonos does not have remote and Sonos app does not recognize wired connection (no way of adding volume from Sonos app for wired connection) - you need to set it manually on Sonos to high volume once - then you can control volume on PC using normal Windows controls. I cannot comment on video quality as I dont see differences - my main monitor is connected via DisplayPort and HDR enabled from RTX card, my second monitor which I sometimes use for movies - is connected via Arcana, and quality is great - I see no difference between monitors so far. When I initially connected the device it did not work - I had to go into menu -> Audio -> and enable Sonos Arc, and also menu -> Audio -> Use eArc only (so monitor is not repeating same sound) After these changes it is pretty much plug and play - I tried removing HDMIs and connecting again, switching off power and it continues where left off in a second or so once connected back

Customer ordered the new JVC RS2100 Projector but wanted to use SONOS ARC ...I was unaware as an installer of any way to get sound from AppleTV4K to Sonos Arc (maybe a splitter ???) A little research and I came across this gem ... I literally just worked right out of the box. FUll atmos decode to Sonos Arc .. Using RUIPRO 8K Fiber Optic HDMI Cables if that matters to you ..it does to me when installing JVC laser projectors ... Be Aware that new AppleTV4k firmware does NOT maintain Sonos Arc as DEFAULT AUDIO OUTPUT ...it reverts to AppleTV Speaker every time you turn on the system or change back to ATV4k from listening to music with Sonos.... This is NOT the fault of the ARCANA product I do wish it had 1 or 2 more inputs but they do have an upgraded product with that capability... Many of you will only be using this because you have an outdated TV without ARC or eARC support ...but it works very well with Projector and Sonos ARC sound bar ....highly recommended ARCANA has developed multiple issues .. 1 needs hard reset after ANY Sonos or Nvidia Sheild update (loss of audio) 2 and change in settings results in loss of Sonos Arc audio 3 GoBlue purchased to at least reset Arcana to default ...Go232 app does not connect to GoBlue with iOS or Android ...... trying to arrange exchange /warranty EDIT / UPDATE I got fed up with the audio glitch / sound dropping out / email tech support that only tries to blame the hdmi cables and setup ..... this product is flawed I replace it with AVSTAR 4K@60Hz HDMI 2.0 Splitter Switch Bidirectional 2 in 1 Out/1 in 2 Out,ARC/EARC Soundbar,Sonos Soundbar,HDCP 2.2,HDCP 2.3 have not HAD 1 issue for 3 months now ..... great performance and NO issues HD FURY FOR SALE OR TRADE
