## Description

DON'T BUY if you only want to use the TV's internal APP with your arc soundbar. We suggest using an external player, for example, Apple TV, for the best atmos effect in your earc soundbar. If you experience sound cut issues, please turn off TV CEC or change your TV HDMI port to a non-CEC HDMI port. No eARC TV? No problem! And no more lip sync issues for eARC TV owners! WORLD’S FIRST eARC adapter allows FULL AUDIO up to Atmos over TrueHD from ANY external HDMI source to ANY eARC sound system. It's the perfect solution for any eARC AVR, soundbar, or headphones.

Review: HDFury Arcana 4K Setup + Review – Projector + Apple TV + Sonos (What Actually Works) - 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.
Review: Awesome little box - does exactly what it says it will do - I bought a Sonos Arc 2 for my 5+ year old Samsung TV (UN49M5300AF) and a desertcart 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 desertcart Prime and Netflix only deliver Dolby Atmos sound to 4k TVs (WTF desertcart 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 desertcart 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).

## Questions & Answers

**Q: If i input hdmi from a blu-ray player to the arcana, can i then use the earc output for a home theater audio system that requires earc input?**

### ⭐⭐⭐⭐⭐ Awesome little box - does exactly what it says it will do

### ⭐ Way too expensive to be this glitchy.
*by R***A on January 26, 2024*

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.
