Meet Arc, Brilliant sound for your TV

Extraordinary sound meets elegant design

Eleven high-performance drivers, including custom elliptical woofers and precisely angled side tweeters, produce vivid detail and impressive bass for home cinema and music streaming. Arc's upward-firing drivers create a multi-dimensional soundstage that moves around you, rendering every whisper and explosion with dramatic clarity, detail, and depth.

With its elongated shape, soft profile, and seamless façade, Arc discreetly mounts to the wall or sits beneath the TV without pulling focus. When mounted, a magnetic sensor detects the orientation and smartly adjusts the EQ to temper bass resonance.

Arc’s sound was specially tuned with the help of Oscar-winning sound engineers to emphasize the human voice so you can always follow the story. The advanced processing creates five phased-array channels that masterfully deliver sound to your ears from all directions at the exact right moment. Use enhanced Trueplay tuning technology to optimize the sound for the unique acoustics of your room, even calibrating the height channels for precise localization.

You can also make a surround sound setup with a pair of our surround capable Sonos speakers, such as a pair of Sonos Ones, or amplify it all with a Sub for an extraordinary surround experience.

Some more details on Sonos Arc:

Thanks!

That’s interesting. Is that a fairly straightforward setup with no downsides? I come from full-on Amplifier setup, so the in/out always seemed natural to me.

In this case - I would have 5 devices into the HDMI switch, then into, say, input 1 in the TV, and eArc out to Sonos as you say. Meaning… I would leave the input on the TV on the same input 1 all the time (I wouldn’t ‘switch’ to the eArc HDMI - say, Input 3 - under this scenario ever?

I just want to avoid switching conflicts - the TV input should be a constant (and the output to Arc as well)…

Thanks again

Sonos needs to be connected to your TV’s Arc HDMI port. Then your switch can be connected to any other HDMI. Then it should work. I will be using this with Caavo on one TV… I don't think there will be any major issues, but I don’t think it’ll pass Atmos from anything connected to the Caavo (we’ll see).

Update - found a response from HDfury in avsforum that notes it will not do what we need:

https://www.avsforum.com/forum/37-video-processors/2902961-hdfury-vertex-owners-thread-163.html#post59617606

So there is not one product, AVR or other that can solve this for us?

No. There is not. I said what HDfury said like 6 pages ago here. It won’t work because Sonos’ products have HDMI outputs, not inputs. If this doesn’t work with your TV, you will need a new TV. Or someone has to innovate a new product designed to solve for this, but I have major doubts that will happen. It would be pretty complicated given the way the Sonos Arc is designed and it would be a product that in some number of not so distant years would be completely obsolete as all the new TVs will have eArc/Atmos support.

I don’t think it’s quite that bad. There’s nothing on the market, but then there’s been little market driver until now. It won’t be obsolete as there is zero reason I can see for mid/high end projects to start supporting eARC and therefore any projector + eARC only soundbar/receiver will hit this. It doesn’t seem far fetched that soundbars/low end receivers may follow the same pattern of single eARC hdmi for cost reduction as TVs with eARC start to become common.

What we want is the module that already exists in various TVs to do this, wrapped in a board & box. Two ports, one audio->eARC embed module, and a PSU if the 5v from HDMI is insufficient. That’s plenty for me as the audio/video split is taken care of already.

I’m sure the Sonos engineers would be able to give a great estimate of what’s needed, but I’m also sure they’re insanely busy at this point. I’ve reached out to a friend of mine to see if he’ll take it as a commission. Will see.

Example module - SiI9438 https://www.latticesemi.com/en/Products/ASSPs/HDMI21eARC
The eval board is more than I want to pay, but the unit price on the actual chip should be more sane.

When can we expect reviews? I figured, reviewers had received their units already but seems not.

Ignoring the fact that I would be compromising the sound somewhat by covering part of the upward firing speakers… I’m wondering if it is possible to mount the Arc to my TV stand using the Sanus TV mount and Arc mount? Currently I have a Beam mounted to my TV stand using the Sanus TV mount and Beam mount and I would like to replicate this if possible.

Hi Ryan,

Thinking of ordering the Arc when it’s available.

I still have a pretty old Sony TV. I am going to change it out but not right now.

Will the Arc function properly with my old Sony KDL52EX700?

It has an ARC HDMI port but not an e-ARC.

How can I set the Arc up for the best possible sound until I change for an e-ARC TV?

I use a bluray player connected to the TV for movies I own, but also stream to the TV from my computer.

Any suggestions?

I’m still studying ARC/eARC etc etc. I’ve ordered an Arc but I’m still very confused as to whether I will be able to benefit from any of the newer sound formats.

I’ve discovered my LG C6 will not pass through any DD+ compressed Atmos signals even if the devices inputting into the TV are Atmos compatible. It will output DD+ happily but no Atmos from any of the internal apps either.

I have an Oppo UDP-203 and I’m thinking of connecting the HDMI 1.4 Audio out from this directly to the Sonos Arc. I’ll put my Apple TV or Xbox One into the HDMI In of the Oppo. I’ll then use the Oppo HDMI input select to choose which input will pass through to the Sonos Arc. (Oppo has a new firmware which allows passthrough of Dolby Vision from the HDMI In)

Will this work?

Will my Oppo pass through the ARC TV Sound? Will it passthrough even if on standby?

At least this way I think I might get:

full bandwidth Atmos from discs (BluRay/UltraHD)
compressed Atmos from the Apple TV or Xbox One apps
though on the downside I might not get any sound from the TV :( unless the TV ARC routes through the Oppo.

Again - how hard would it have been to put just a HDMI through input and out on the Arc?

It feels like you need a PhD in HDMI technology to figure out how to get the best out if this device!

I’m still confused with the Dolby Atmos support.

At the moment I have a Beam, 2 One’s and a Sub. Most of the video content is coming from the Apple TV. In the settings of mine TV (Philips 55POS9002) the audio is set to multichannel (bypass) and I get a proper Dolby Digital 5.1 sound.

But now I want to trade the Beam for the Arc but I’m not sure if I really get an Atmos sound. Mine TV does not support eARC and in the documentation of the Apple TV you can find that the Apple TV 4K uses a high bandwidth form of Dolby Atmos that doesn’t work over ARC connections.

But it is also possible to get the Atmos signal within the Dolby Digital Plus signal which can be transmitted with ARC. But I’m not sure if the Apple TV support this?

If the Apple TV doesn’t support this then it seems to be impossible to get an Atmos signal from the Apple TV when your TV doesn’t support eARC, I’m a right?

Unfortunately, no.

To me anyway, the simplest way to look at it is remember that ARC stands for Audio Return Channel. Return means that the audio is flowing in the opposite direction of the way video will flow, from an HDMI Input to an HDMI output, both of which need to be ARC or eARC capable. The HDMI port on your TV is an Input, while the port on the Arc is an Output. You can’t connect your Bluray player’s HDMI output to the Arc’s HDMI output...it won’t work.

I thought I was getting it..obviously not.

So what signal is the Arc outputting to the TV? (I could understand handshaking to tell the TV what audio formats it can receive and how it wants them).

I thought the Audio Return Channel represented Video In (to the TV) and Audio Out (from the TV) going two ways bidirectionally in the same cable? Are they not both HDMI inputs at both the Arc and TV ends?

Hello,

I think this soundbar looks very good.

I have one question about it. Now I have a multimedia player (Nvidia Shield) connected directly to the soundbar (Yamaha YHT-S401) with HDMI and the soundbar connected with HDMI ARC to my TV (Panasonic VT60). I see in my soundbar all the different codecs (DTS, Dolby,...).

Can we do the same? Connect the Nvidia Shield to the Sonos Soundbar by HDMI and then the Sonos ARC to the TV with the HDMI ARC?

I think its the only possibility, because my tv its old.

Thanks
