Published 5/10/20

Exciting things are happening at Sonos. They have just announced the June 10, 2020 release of a much anticipated addition to their family of Home Theater speakers. That being the Sonos Arc with Dolby Atmos.  

An obvious question is how will the Arc fit into the Sonos line-up apart from the fact that it is capable of bringing the Dolby Atmos experience to home theater entertainment? Hopefully the chart below will answer some of those questions.  As you review the chart keep in mind that those points highlighted in blue are footnoted.

The Sonos Amp has been added to this group; although not technically a speaker, it can be used in Home Theater to power 3rd party speakers for left/right front channels or Sonos in-wall (left/right) architectural speakers by Sonance.  Doing so it approximates the Center channel referred to as a “phantom center”. It can also be used to drive a pair of 3rd party speakers (typically book shelf or in-ceiling) as surrounds. Sonos in-ceiling architectural speakers by Sonance can be used as surrounds as well. 

As always Community Members are here to assist and answer additional questions/points not covered in the chart. Cheers! 

Discontinued: The Playbase and Playbar will no longer be manufactured. They are still available through Sonos (via Last Chance) and select retailers while supplies last.

Soundbase: The Playbase surface area measurements of width and depth are sufficient to allow placement of a TV weighing 77 lbs., (34.9 kg) on top of it when supported by a desk or table.

Music: Downloaded refers to music that is stored on a tablet or cell phone (iOS/Android), Computer (Windows or OSX) or Network Attached Storage (NAS).

Home Theater: See paragraph on Sonos Amp above

Dolby Atmos: You’ll need a TV that includes an HDMI eARC port (and 4K Blu-ray player) to reproduce the lossless Atmos playback that the Arc offers.  Older TV’s with only HDMI ARC can enjoy compressed Atmos through popular video streaming services.

On its own, the Arc can serve as a 5.0.2 Atmos system. It always mixes seven-channel audio feeds down to five. The Arc’s eleven (11) speakers work in channels comprised of multiple speakers.

  1. Left Front Channel x 2 / Center Front Channel x 3 / Right Front Channel x 2
  2. Left Side Channel x 1 / Right Side Channel x 1
  3. Upward Firing Channel x 2

Items One & Two above represents the 5 in 5.0.2

Item Three represents the 2 in 5.0.2

Zero (0) is a place-holder in 5.0.2; but changes to One (1) if a Sonos Sub is added making the Arc a 5.1.2 sound system.

When reproducing material that doesn’t contain Dolby Atmos audio, the upward-firing speakers will focus on low-end response.

When a Sonos One/One SL (x2) or Play 5 (x2) or Five (x2)  or Play:1 (x2) or Play 3 (x2) are used as surrounds the Arc’s side firing speakers revert to lend support to the left/right channels.

Since the Arc has built-in voice assistant capability for either Alexa or Google the Sonos One SL is recommended over the Sonos One as the voice assistant capability will be muted in the Sonos One.

Also a Play 5 cannot be used with a Five to create the surround channel.

Note: Incidentally, the last two statements also apply to the Beam.

TrueHD / MAT / Dolby Digital Plus / Dolby Digital: If you connect to a TV with eARC, the Dolby audio formats supported include Dolby Atmos, TrueHD, MAT, Dolby Digital Plus, and Dolby Digital.

If you connect to a TV using ARC, the Dolby audio formats supported are dependent on your TV model and manufacturer. The TV may be capable of sending Dolby Atmos, Dolby Digital Plus, and Dolby Digital. An ARC connection cannot support TrueHD or MAT.

If you connect to a TV using the optical adapter, the Dolby audio formats supported are dependent on your TV model and manufacturer. The TV may be capable of sending Dolby Digital. An optical connection cannot support Dolby Atmos, TrueHD, MAT, or Dolby Digital Plus.

Mono: The Amp is capable of stereo or dual mono sound.

Alexa & Google Assistants: These assistants accept voice commands received via far-field microphone technology embedded in the Arc and Beam. Select either Alexa or Google for native support. Playbar and Playbase require Amazon or Google device integration.

HDMI eARC / HDMI ARC: See Dolby Atmos, TrueHD, MAT, Dolby Digital Plus and/or Dolby Digital above. The Beam and Amp only support HDMI ARC.

Line-in: Amp Sources Supported: Audio device with analog RCA output or optical output (optical adaptor required). 

Subwoofer Output: Subwoofer output: Auto-detecting RCA type, user-adjustable 50-110 Hz crossover

Speaker Output: Speaker output connections: Banana plugs (2) capable of stereo or dual mono sound

TV Autoplay: Audio can be enjoyed via speaker automatically when a signal is detected.

TruePlay Tuning: Using an iOS or iPadOS speakers can be tuned via the Sonos app to room environment for ultimate enjoyment of movies and music. 

Limited feature via Sonos Amp that is only available when using Sonos in-wall or in-ceiling architectural speakers by Sonance. Does not work with 3rd party or Sonance outdoor speakers.

Apple AirPlay2: Native to Arc, Beam and Playbase. Playbar can be grouped to a Sonos speaker with AirPlay2 capability (typically a Sonos One/One SL, Play 5, Five, Move, Port or Amp) to facilitate whole home music audio.

Sonos S1 and S2 Software: All new Sonos products starting with Arc, Five and upgraded Sub will not be backward compatible to Sonos S1. Some existing Sonos products will continue to work with Sonos S1 software and the more powerful Sonos S2 software. For complete details on Sonos S1 and S2 software (as well as compatible products) click this link.

LED Status Lights: LED’s on the Arc will dim according to room lighting conditions.

Wall Mountable: The Arc will sense when mounted to a wall and lower bass response to prevent low-end vibrations.

Please do...but no need to send a video as that requires too much bandwidth. Here’s my suggestion: 

  1. Take a picture of your Sonos products in tack
  2. Take a picture of your Sonos products smashed 
  3. Take a picture of your Sonos products on fire 🔥 

That would be hilarious. I’m sure everyone will enjoy seeing your money go up in smoke. 😂

 

Nah, go for the video.  It’s been a while since the last Jackass film.

I would be happy to send you a video of me totally sledgehammering my SONOS products and setting the pile on fire. New Years eve bonfire.


“first-world luxury electronics manufacturer” Luxury my A**

 

Truly pathetic. 


“first-world luxury electronics manufacturer” Luxury my A**


I really don’t give a **** about you flagging my posts. Plenty of other places to post what a shit company you are.

 

A worldwide pandemic going on, 100’s of thousands of deaths, millions out of work, and you’re here throwing a tantrum because a first-world luxury electronics manufacturer isn’t catering to your every beck and call?

Get a life.

Buy one, steal one, borrow one if you have to, just get one.


@Zzyzx 

We’re watching you. 

 


I really don’t give a xxx about you flagging my posts. Plenty of other places to post what a x company you are.

 

Edit: Offensive language removed


WOW...I see you made your thoughts known in several threads...with all that said...how do you really feel about Sonos?

BTW...I’m flagging your posts for language.


Do a google search on <Sonus support ****>. I actually was stupid enough to believe your company was top notch, not, 1.4 rating. Lots of complaints. I’m going to sledgehammer all my sonus products to bits, place in a pile, douse with lighter fluid, light on fire while taking a video of it all and post it on SM sites and tell the world your products are a pile of xxxx. I’ll make sure to send you a personal copy.

Hi @TimsTelegram 

Here are the answers to your questions (only currently marketed speakers are discussed):

  1. It’s really neither. Th Sonos Amp is designed to power 3rd party speakers as left/right front speakers in stereo. It can be used in a home theater setup with a matching pair of Sonos One’s/One SL’s or Five’s x2 as surrounds and a Sonos or 3rd party sub to create DD5.1. However the center channel will be a blending of the front let/right speakers to create a “phantom”  Center channel. Note: A second Sonos Amp can be used to power Sonos in-ceiling/in-wall or 3rd party speakers as surrounds.
  2. The only Sonos speaker capable of delivering Dolby Atmos is the Arc
  3. When using the Sonos Amp to power left/right in-wall speakers the results are the same as outlined in the answer to question 1. Neither an Arc nor Beam can be integrated with the Sonos Amp to add a center channel.
  4. Only as follows: Sonos Arc with Sonos or 3rd party Sub and Amp used to power Sonos or 3rd party speakers as surrounds (DD5.1.2)
  5. YES to part one and NO to part two when using an Arc or Beam.
  6. Regarding the Sonos Amp it is explained in the answer to question 1. The Sonos Arc is the only speaker capable of DD5.1 and Dolby Atmos. The Sonos Beam will only allow DD5.1. A Sonos Sub combined with Sonos branded speakers mentioned in the answer to question 1 can be used as surrounds with either the Arc or Beam.  3rd party or Sonos branded in-ceiling/in-wall speakers by Sonance can be powered by a Sonos Amp and used as surrounds with the Sonos Arc or Beam.

Hopefully I’ve answered your questions.

Cheers!


A big thank you to @AjTrek1 for doing what Sonos should have done. A couple more questions:

  1. Does anyone know if the limitation of the Sonos Amp to Dolby 5.1 (and thereby exclusion of Atmos) is a software or hardware issue?
  2. And...if someone wants an Atmos setup they are stuck with a soundbar? (That seems counterproductive)
  3. What if someone wants to use the in-wall speakers with the Sonos Amp. Does that mean they need to add an Arc to decode Atmos?
  4. Can a discrete 7.1( or Atmos 5.1.2) system be made? For example, Sonos Arc(3.0.2) plus Sonos Amp(2.0.0) plus Sonos Sub(0.1.0) even be built?
  5. Must the Sonos Arc be the Left-Center-Right channels? Is it possible to use another Amp to replace the front L/R channels? 
  6. Is there a map for all the possible combinations or at least the possible channel configurations?

 

Also, a note for Sonos...how come none of these specs are on the product pages, especially the Amp? 


@Kyutsa 

Please start your own post as your question will not get the visibility it deserves hidden in this thread.

Cheers!


There is something off about ARC when playing music compare to the Beam as the main. Its not loud and the two sonos 1 overwhelm it. The Beam synchronises with 2S1 + Sub better. Its like I cant hear the ARC enough and its not as crisp as Beam. The whole ARC+Ones+Sub sounds unbalanced. btw its on surround FULL music playback.
What should I do? Im not happy with the Arc SOUND!?!


First of all, awesome chart. It helps a ton. This should be Sonos does an official link. Personally I think they should put an Introduction for Home Theater or getting the most/what you can and can’t do, tips and tricks as a dedicated separate page on the website. Maybe even have a YouTube show instead of people outside the company.  It would be a lot easier than combing thosands of posts on the community. Especially as often you have conflicting information. Be proactive and honest and we might complain but would respect them more. When it was just audio it was one thing but when they opened it up to Home Theater it multiplies by a factor of 100, especially with all the different products, sound options, etc. we choose Sonos for simplicity (and great sound) and they should be dedicated to making it as simple as possible which again was and is a key selling point. 


Thanks for the chart!

How about adding the Amp?

I know that it’s not a speaker, but it could be useful for comparing audio formats.


Shouldn't Dolby TrueHD be added to the list? Supported by Sonos Arc but not any other device

Added TrueHD and MAT along with proper footnotes.

When a Sonos One/One SL (x2) or Play 5 (x2) or Five (x2)  are used as surrounds the Arc’s side firing speakers revert to lend support to the left/right channels.

 

Why isnt’t the Play 3 (x2) mentioned here?

 

@mucullus 

When developing the chart I only thought to include current Sonos stand-a-lone speakers. LOL. I’ll add the Play 1 and Play 3.  Thanks for asking.

Cheers!

I had read the Arc doesn’t support multichannel PCM but the Beam does. Is that correct?

Where did you read that the Beam supports multi-channel PCM?  Please provide a link.

Also you may have your terminology crossed. You are probably thinking of Linear Pulse Code Modulation (LPCM).

ah, well I read that the Arc doesn’t support multichannel PCM here (https://www.reddit.com/r/sonos/comments/gerkkc/no_multichannel_pcm/ ) and as I get surround from my Nintendo Switch to Beam +oneSLs I assumed it was doing it. 
 

What’s the switch surround doing then?

 

Will the Beam be able to be upgraded to DD+ following S2, I wonder?

I’m not familiar with the Nintendo Switch. If when you go to: Settings > About my System > Sonos System Info and view Audio -In for a room whatever that says is what you are hearing. (DD, DD5.1 or Stereo).

Only Sonos knows if the Beam will allow DD+ with the S2 software. Although I seriously doubt it...as embedding a codec is a little more complicated than merely sending a script.

I agree. It seems highly unlikely at this stage.
 

From a commercial point, if Dolby Digital Plus was coming to older products (Beam and Amp) it would have made sense to announce it together with the Arc as general news of Sonos now supporting the codec.

The Beam cannot support PCM 5.0 as ARC does not support it. Only eARC can handle PCM 5.0. ARC can only do PCM 2.0.
