I am a new owner of Sonos system (Arc, Sub and 2 One).

I'd like to ask if it's possible to connect an EPSON EH-TW9400 projector (no HDMI output or optical port) to my Sonos Arc to get audio dolby atmos.

Is it possible If I use HDfury Arcana or any other HDMI adapter?

Thank you in advance.

I asked the folks from HDfury but unfortunatelly they don’t know… Disappointing…

Let me ask another question.

If I connect the Arcana to Sonos Arc using an active HDMI 2.1 or an optical HDMI 2.1, is it possible to have dolby atmos audio?

If both of them are possible to work, which one is better?

Thank you in advance!

Use the cable that come with the Arc to connect Arcana to Arc. Active HDMI should be used for longer distance runs, and shouldn’t be necessary assuming the Arcana is placed on the same side of the room as your Arc. Active cable is probably what you want to use to Connect your Arcana to the projector, assuming they are on different sides of the room. I use Active cables with some outside TVs, where the source and Sonos amps are 20+ft away. No issues, although it’s 4k 60hz and 2.0 audio in those cases.

Also, per your earlier question regarding video quality, HD Fury is primarily about video quality and specializes in things like converting dolby vision to HDR, or downgrading video when using multiple displays of different quality. So generally, they are going to be better for video, but depending on your projector and specific needs, might be overkill or unusable for you. Also they have the VRROOM which contains all the Arcana functionality plus HD switching capabilities. Very costly though.

It’s not possilbe to use the cable that comes with the Arc to connect Arcana to Arc, because of the distance. There are the following 3 possible options (setups)

Option 1: The Arcana is 0.5-1m (I count the cable length) far from the source (Nvidia or laptop/PC) and 5m far from the projector and 15m far from the Sonos Arc.

Option 2: The Arcana is 10m (I count the cable length) far from the source (Nvidia or laptop/PC) and 10m far from the projector and 5m far from the Sonos Arc.

Option 3: The Arcana is 0.5-1m (I count the cable length) far from the source (Nvidia or laptop/PC) and 10m far from the projector and 5m far from the Sonos Arc.

Which option is better and what kind of HDMI cables must use in order to get video 4K 60Hz and 3D FHD and audio Dolby Atmos?

From an aesthetic point of view, the first option(setup) is a bit better because almost all the device and cables can be hide.

PS: My projector Epson EH-TW9400 has a usb port for Opt.HDMI power supply (300mA). So, a fiber optic HDMI with a power supply can be used to connect the projector to the source (Arcana in my case). I note it in case this is a solution to my problem.

Eh. Options 3 is better, but using active cables for the 5 m or more runs, you should be ok. Option 2 might be the worst since you have a total run of 20m between source and projector. However, I believe Arcana will inject power for the second leg of that run.

I think I would buy enough cables to handle all 3 options, test them out before burying anything behind a wall, and return the cables you don’t need.

Thanks for the instant response, I'm greatful!

In option 1 the arcana is 15m far from the sonos. Which is the best type of cable, using an active HDMI or a fiber optic HDMI cable? Both types must be HDMI 2.1, right? For dolby atmos audio, of course.

I’m not familiar with any optical fiber HDMI cable, and hence no version of 2.1 HDMI on optical? There’s a bandwidth issue, I was led to believe, when using optical, in as much as it can only handle audio, not video, and only “up” to Dolby Digital, not Dolby Atmos.

Can you provide a link to this optical HDMI stuff? I’d love to learn more about it.

Some optical fiber HDMI cables are the following:

https://www.cablematters.com/pc-1337-142-certified-active-ultra-high-speed-hdmi-cable-fiber-active-optical-8k-hdmi-cable-designed-for-xbox.aspx

I haven’t use any of the so I don’t know anything about their performance.

Can anyone suggest specific reliable HDMI cable (hope not very pricey) for the following?
