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:

Simple to set-up. Plug Arc into power and then connect it to your TV using the HDMI-ARC cord. Bring your phone up to Arc to automatically pair and securely transfer WiFi credentials using near-field communication (NFC).
HDMI eARC. Increased bandwidth supports high-quality audio and has lip-sync compensation built in.
Dolby Atmos. Play Atmos and Atmos-encoded audio to play from your collection and favorite services through your TV’s HDMI ARC or eARC connection.
Ambient light sensor. Arc detects how bright the room is and automatically adjusts the brightness of the LEDs to be visible but not distracting.
Automatic remote sync. Arc connects to your TV's HDMI eARC port with a single cable and automatically syncs with your remote.
Control your way. Control Sonos Arc with your voice, the Sonos app, your existing TV remote, your favorite music service’s app, or AirPlay 2. Capacitive touch controls for play, pause, skip tracks, adjust the volume, and group rooms just by tapping or swiping the top of the soundbar. LED indicates status, mute status and voice feedback.
Smart voice recognition. A four far-field microphone array used for advanced beamforming and multichannel echo cancellation makes sure you’re heard, even when the music is blasting, even when playing in immersive surround sound. For privacy, turn the microphone off with a tap. The LED light is hardwired and will always indicate if the microphones are enabled or if your voice assistant of choice isn't listening.
Optimized for your listening. From within the Sonos App, tap Speech Enhancement so you never miss a word, or Night Sound to amplify quiet noises and reduce loud ones so you can enjoy late night TV without waking the entire house.
Tune with Trueplay. Trueplay puts the speaker-tuning capability of the pros in the palm of your hands, adapting and optimising the sound of the speaker to the unique acoustics of the room. iOS device required.
Low profile and compact size. The dimensions are 3.4 x 45 x 4.5 inches (87 x 1141.7 x 115.7 mm) H x W x D and Arc weighs 13.78 lbs (6.25 kg).

Hi,

I am new to Sonos, but was considering buying the Arc Surround set - but am a little confused about the “One HDMI” port? I am familiar with eARC and my 2020 OLED supports it. That said, I am planning to go multiple inputs to a (high end) HDMI switch (full bandwidth) then into the soundbar, then out to the TV. Otherwise it’d be impossible to connect my 5 input devices (not counting the TV)). How would that work if the Arc only has ONE HDMI port?! Or does Sonos mean it’s ONE input and ONE Output?

eArc doesn’t help me here as far as I can tell/

It's one input only. Sonos soundbars are designed so that sources connect to the TV directly, and the TV sends audio to the Sonos device via ARC or optical. In your case, go from the switch to a non-ARC input on the TV, then HDMI-ARC out on the TV to the HDMI in on the 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

so I'm clear. the Arc will still get audio from the same optical cable I'm using with my playbase from my TV. Thus my TV must be ATMOS capable to get the ATMOS. LG OLED b557a has this? Cant find online for sure. assume it does. also from what I have been reading my old subwoofer and play 1’s will be compatible?

What high-end HDMI switch are u using if I may ask?

The Arc can use the same optical cable your playbase used, however, it’s impossible for Atmos signal audio to transmit over an optical cable. For the Arc to play Atmos content, it must receive the content over HDMI-ARC or HDMI-eARC. Your TV will need to have a HDMI input labeled ARC or eARC. I tried to find information on your specific TV, but had trouble finding a manual or picture of your TV’s input to confirm this.

Your existing Sonos sub and play:1s will work with the Arc.

It can, using the same adapter used by the Beam when connected to optical. However, you will not get Atmos from that arrangement as there is not enough bandwidth available In optical to carry the Atmos data, so you’d be restricted to Dolby Digital. If you want to get Atmos content, you must be using either HDMI ARC or eARC.

thx both of you guys. Looking to get the ARC to mainly upgrade to ATOMS.Thats what all my compatibility questions are leading to. I do have an HDMI in (ARC ) port on the side of my TV. the word “in” confuses me. With my playbase the optical cable run from the out port on the TV to PB. So how come the HDMI arc port is an “in”. doesn’t sound flow from the tv to the ARC device.

It’s technically both. It can receive data into the TV, but it returns audio on the ARC channel (ARC = Audio Return Channel). In the case of the Arc, there’s not much going in, and the Audio from all the other HDMI inputs is going out. So say you have a cable box, a streaming device, and the Arc, and your ARC capable HDMI is HDMI #1. You connect the Arc to HDMI #1, your cable box to HDMI #2, and your streaming device to HDMI #3. To watch cable, set the input to HDMI #2 and the audio goes out over the ARC channel of HDMI #1. Same thing with the streaming device, set input to HDMI #3, and the Arc will get the audio over HDMI-ARC from HDMI #1.

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.
