Welcome! Here you can find tips and tricks, how to get started, and many answers to the questions you might have about how to use the Sonos Amp. For the basic details, check out our introductory post on the Amp and our product guide.



The Amp is a great solution for anyone with their own passive speakers that they'd like to bring into the Sonos world. It's for people who are designing a home and want to install speakers in walls or ceilings. Use the Amp with your TV, or to bring sound outside. There are a dizzying amount of options, and this thread should help ease your mind and help make some decisions, so let's get started.

What is Amp?


Sonos Amp is an amplifier for passive speakers, bringing the Sonos experience to your own speakers. It brings all the Sonos music services, functionality, and ease of use to speakers installed your home. Along with all other Sonos speakers, Amp is capable of receiving voice control commands from microphone-enabled devices, such as the Sonos One.

Amp has an HDMI-ARC and Analog RCA input, allowing for a lot of customization and different setups. Amp plays Dolby Digital 5.1 or PCM stereo sound over HDMI-ARC.

Regarding speakers, Amp puts out a powerful 125 watts per channel at 8 Ohm to a max of 6 speakers, scroll down for more on speakers.

Amp Setups


The greatest thing about the Amp is its versatility, no matter if it's wall-mounted, sitting on a center console, hiding in an audio closet, or stashed behind a TV, Amp can be used with in-wall, in-ceiling, outdoor, free-standing towers, bookshelf, and any other type of passive speakers. Up to two pairs of speakers or three pairs of the Sonos Architectural by Sonance, which are specially designed for use with Amp.

Hook up the Amp to a record player (phono-preamp may be needed), CD player, or other analog audio connection, or connect it with your TV to amp up your home theater.



Home Theater setups with Sonos Amp
Designed with home theater in mind, Amp has HDMI-ARC for audio with high quality (Dolby Digital 5.1 and PCM stereo). You can use your IR TV remote with Amp to adjust the volume, and when paired with a voice controlled device, the Amp can send commands to your TV over HDMI-ARC CEC.
A single Sonos Amp can be used as front or rear channels for a Sonos surround sound setup. You can use two Amps together for the full surround sound (4.0 or 4.1 with a Sub or attached subwoofer) setup. When used as the main home theater speaker, the front channels, center audio is generated by the left and right channels working together. The Amp can be bonded with a pair of Sonos speakers supporting surround channels (Play:1, Sonos One, Play:3, Play:5 gen2...).

When used for the rear channels, Amp will wirelessly pair with any other Sonos home theater device (Amp, Beam, Playbar, or Playbase) over 5GHz. Please note, when operating as the rear channels, the subwoofer output and audio inputs on the Amp are disabled.


Installing a new Amp


New to Sonos and the Amp? Here's what you'll need:
  • Sonos App on iOS or Android.
  • Wireless router broadcasting a 2.4GHz network.
  • Passive speakers you want to use with the Amp, and the wires to connect them.

To get started, first install the Sonos App, then follow the instructions in the app to connect your Amp to the network and get registered.

The biggest trick to installing an Amp might just be figuring out how to run the wires to your speakers. You might be looking to wall mount or use built-in speakers, so a customer AV installer may be someone you want to reach out to. You can find a list of Sonos installers in your area here.

Use the Amp with 2, 4, or 6 speakers. If you'd like to use 6 speakers with the Amp, use the Sonos Architectural by Sonance.

To install speakers with your Amp, you'll wire the + and - cables from the right speaker(s) back to your Amp, using the black and red ports marked right, and then again the same for the left. Use the included banana plugs, which you unscrew to open up and make wider for larger gauge or multiple speakers.


For more details and diagrams, check out our support article here.

Amp Mounting
Amp can be mounted with the bottom flush against the wall, vertically mounted to hide behind a TV or in a small space. Ensure that there's an inch on all sides for airflow. The Amp wall mount is available here.

Rack mounting the Amp is also possible. The Amp was designed for home audio installation specifically designed to fit well into a rack of audio equipment. There's a screw on the bottom to secure the Amp into the location.
There are several options for rack mounting the Amp, as they will nicely fit in with a standard audio installation. You can get an impressive wall like this one:



Speakers


Use your own passive speakers with the Amp. For setup, Amp comes with custom banana plugs that accept 10 - 18 AWG speaker wire and the Class-D digital amplifier sends a maximum of 125W per channel at 8 Ohms. This is more than twice what the older Connect:Amp pushed out. You can use 2 pairs of 8 Ohms speakers with the Amp, or if you're using the new Sonos Architectural by Sonance speakers, you can use up to 3 pairs.

The Amp also has a subwoofer output that's auto-detecting RCA with adjustable crossover, between 50 to 110Hz, if you'd like to use your own subwoofer. You'll need to be using an independently powered subwoofer. Please note, when operating as the rear channels, the subwoofer output on the Amp is disabled. Amp will also bond with the Sonos Sub.

When connecting speakers with the Amp, you'll use the included banana plugs and follow the installation instructions above.

To purchase the Sonos Architectural by Sonance, you can find them respectively here for the In-ceiling, In-wall, and Outdoor speakers. Hot Tip: If you're using these Sonance speakers, make sure you go into the Sonos App > Settings > Room Settings > Trueplay and Identify the speakers (it really can improve the sound a lot).



Trueplay and Amp


The Amp is Trueplay capable when paired with in-ceiling and in-wall Sonos Architectural by Sonance speakers. These speakers have been specifically designed to be capable of Trueplay tuning with the Amp and will be automatically detected using the Sonos app.

Trueplay tuning will only function in one room with an Amp, so if you're wiring speakers in multiple rooms with the Amp, you'd be best off not using Trueplay.

Home theater setups using an Amp as the rear surrounds will also be able to Trueplay. The surrounds don't need to be Sonos Architectural speakers, but if they are, you'll be getting finer tuning and a better experience when using them. Please note that if you're using two Sonos Amps for a home theater setup, you will need to be using the Sonos Architectural by Sonance speakers or Trueplay won't show as an option.

Thank you!  I do recall that it can do 4.1 and the 5th channel ends up being a virtual channel?  Don’t really understand the how or why but I get it. 
 

I’ll go read the links you’ve provided and let you know how it goes. Thanks again for the quick assistance.

Hi,

I’ve been using my amp and I love it.  It has great versatility, and I’ll use it with external speakers and group it with the rest of my house simultaneously to play LPs.

A couple questions:

  1. given that it doesn’t have standard line in, what would be the best way to connect my PC to it?  Is there a way to use the HDMI arc port, given that the RCA line in is taken up by my record player currently?
  2. any benefit or best practices to using the amp to support streaming services such as spotify premium?

Thanks!

I am looking to impliment this variant, similar to some others here but (I think) slightly different.

In the same room I want to have a music setup and a surround setup, that shares some components but not others.

This is what I am thinking.…

 

Music (2.1) System: Amp powering 2 passive 3rd party speakers, Amp bonded to Sonos Sub.

Home Threatre System: Beam bonded to Sonos Sub, with 2x Sonos Ones as Rear Left and Right, and IDEALLY using Amp/2 passive speakers as front left/right BUT this is sacraficible as those speakers are not equal distance from the tv (one is quite close, the other 2m away). I suspect I will have to ditch these OR the Beam in this set up.

If I need to compromise/adjust this that's fine but the one thing that I definitely want is to utilise the Sonos Sub for music AND home threatre, even if that means going onto the app to remove it from one and add it to the other when necessary.

TV does NOT have ARC (sadly)

What do you think, is this possible:

1) switching the use of the Sub between the Amp/passive speakers and the Beam when needed.

2) with the passive speakers acting as Front L/R with Beam, Sub and Ones completing the full surround.

Cheers in advance for any input/thoughts.

  1. I have found that unbonding and rebonding the SUB, and then re TruePlaying the room to be onerous. You may feel differently.
  2. If you’re using one of the Sonos sound bars, you are not able to also have Left and Right speakers. All Sonos sound bars contain the right, center and left channels in the single box, and the software doesn’t provide an opportunity to split them out. You could instead use the Sonos Amp to drive third party speakers as right and left, and have the “phantom” center created by Sonos. In that situation, you could use a second Amp to drive the surrounds, or use other Sonos speakers as surrounds.

Thanks Bruce, that's what I suspected. I'm not sure I always want the TV coming through my main speakers/with full surround (e.g. when our daughter is watching something) - so if I went for the Amp+passive speakers Front L/R, Sub, and possibly Sonos Ones as Rear L/R, can I easily disable/enable the entire Sonos routing so sounds just plays through the TV. I know that is dependant on others things like the TV but I guess I just keep the Optical connection between the TV and Amp unplugged, and plug it when we are going to watch a film/want full surround sound...

...another thought.

 

If I only had Beam, Sub and Amp (powering 2 passives), I could easily switch between these two setups just by using the 'remove sub' and ' add sub' button if they are set up as individual 'Rooms' (even though they are in the same physical room) :

Beam and Sub in 3.1 surround (for films)

Amp and Sub in 2.1 stereo (for music)

 

That way I wouldn't need to reapply Trueplay each time as the Beam settings wouldn't change and it would just be a 3-4 button press operation to switch, which would only be when we watch a film once or twice a week (for normal TV I'd leave the Beam disconnected).

Is that right?

When you remove any speaker from a “room” in the Sonos software, it automatically strips any TruePlay tuning from that room. 
 

Depending on your setup, that may, or may not be an issue. Since there is zero cost in the experiment, beyond your time, I’d suggest that you try it, and see how it works for you.

Ok thanks... Back to the drawing board then.

I don't own any Sonos stuff yet, so want to know what will work before spending £1k+.

You're input has been invaluable, many thanks!!!

Why would you want to disable surround sound?   I’m not following what the concern is regarding your daughter. Are you think it will be too loud or scary, or something of that nature.  I honestly wouldn’t think so.

 

Regardless, I don’t know that unplugging the amp would work well.  Your TV is still going to send audio over the optical connection as it would not know the amp is unplugged.  You would need to reconfigure TVs audio settings each time.  But you could prevent the rear channels from coming on by unplugging them, maybe a smart plug. Not exactly recommended, there would be boot up time, etc.  That way sound is only from the Beam/Amp + sub.  I wouldn’t recommend unplugging the sub as the Beam/Amp won’t make up for the missing bass.

Hi Danny.

Thanks for your response.

Here are the three scenarios and what I would want in each (ideally)

i) Films: surround sound, either 3.1 or 4.1 as seems to be the options.

ii) Music: Stereo 2.1.

iii) TV: TV speakers (My Little Pony through a  4.1 system just makes my teeth crunch!, though to be honest we only generally watch comedy so don't want it played through the stereo system, surround or not). 

FYI in iii) I would just disconnect the optical cable and turn the volume back up on TV (or whatever was needed).

Also FYI, if I had 2 x Sonos Ones to act as Rear L/R (and access Trueplay if using Amp rather than Beam), these would live in separate rooms normally and just be moved into the TV room when wanting full surround and/or Trueplay.

Basically my main passion is music and this would be any gears primary purpose, but having the facility to have an immersive cinema experience without too much extra outlay is obviously appealling. Which is where Sonos wins over others.

From previous post I think I am having to ditch the idea of having two 'rooms' that I can switch the Sub between. 

I think my current preference of the possibilities is Amp driving 2 passives, with Sub and 2 x Sonos Ones. TV will connect to Amp as and when needed via Optical, at which point I may or may not bring in the Ones for surround/Trueplay. If I can't be bothered bringing in the Ones/resetting up Truplay I believe I can still adjust L/R balance of passives and overall bass/treble to ensure dialogue comes through.

....I think!
