About the Sonos Amp

Sonos Amp with TV and speaker

More power, more possibilities

Do you love the convenient streaming capabilities of Sonos, but want to use your own speakers? The Connect:Amp was the go-to solution for that scenario for years. Now, the new Sonos Amp has even more to offer.

With 125 watts per channel, it has more than double the power of its predecessor. It will easily power a pair of bookshelf speakers in your office, towers in the living room, or outdoor speakers on the deck. It's also a great solution for those architectural speakers in your wall or ceiling.

Music and more — anywhere you want it

Connect your disc player or turntable with a built-in phono preamp to the Amp to enjoy vinyl or CDs — not only on the connected speakers, but also throughout the house, wherever you have a Sonos player. The Amp's HDMI input means the same thing goes for your TV's audio.

Top of Sonos Amp with a circle-in-square design

Sonos wanted the Amp to be a visual representation of music, so its circle-in-a-square design is reminiscent of turntables, records, and CDs.

And like all Sonos products, the Amp works seamlessly with a host of streaming music services, including Pandora®, Spotify®, and TIDAL. You also have access to thousands of radio stations with TuneIn and iHeartRadio. And if you subscribe to SiriusXM, you can listen to all your favorite programming on any Sonos player in your system.

Want to pick up where you left off in your audiobook or podcast? You can do that, too. 

Easy app control

You can use your smartphone or tablet to control any and all Sonos components in your system. Download the free app to turn your mobile device into a full-fledged Sonos controller. Easily navigate and search through playlists and tracks stored on your computer, or select an internet radio station. Create customized playlists on the fly for individual rooms or for playback over your entire Sonos system. You can also mute or adjust the volume of each of your players.

Compatible with AirPlay 2

The Sonos Amp has AirPlay® 2 built in. That means you can stream audio directly from your iPhone®, iPad®, or Mac® computer through your Sonos system. That includes soundtracks from YouTube® videos and Netflix movies.

And if you subscribe to Apple Music®, you can do even more. Use Siri on your iPhone, iPad, or Apple TV 4K to control Apple Music with voice commands. Tell it what selection or playlist to play — and which Sonos speakers you want it to play through.

Thoughts from Morgan — Crutchfield Commercial Design Specialist

"We are very excited about the new Sonos Amp because of upgrades like HDMI connectivity, AirPlay 2, and additional power. This version is also clearly designed with the professional installer in mind — it's rack-friendly with a clean, black finish that looks great when installed with other components. And I like that it can output in mono for installations where speakers are too far apart for true stereo sound."

Back of Sonos Amp

Sonos will work on your existing Wi-Fi® network. Or, you can connect the Amp to your network router, and Sonos will create its own dedicated wireless network for even better performance.

Installation tips

When you're running speaker wire from the Sonos Amp inside your home to the speakers outside, wall plates can help keep your installation neat and tidy. We recommend a dual-speaker "strap" with a decorative wall plate, or a convenient in-wall cable access port.

Integrated Amplifier Section

125W x 2Ch Amplifier: The Sonos Amp features a built-in state-of-the-art Class D amplifier that can power large or small speakers so you can enjoy superior audio in practically any room. Packing 125 watts per channel into 8Ω or 200 watts per channel into 4Ω, the Sonos Amp powers even the most demanding speakers. And because the Amp is 4Ω stable, you can even power up to four speakers instead of just two. Use the Amp to power your bookshelf, floor-standing, in-wall, and in-ceiling speakers. Thanks to its centralized heatsink, air inlets, and a discrete output stage, the Sonos Amp is built to stay cool and deliver lasting power.

Note: The Sonos Amp can drive a pair of loudspeakers with a nominal impedance above 4Ω or two pair of 8Ω loudspeakers wired in parallel. Do not wire speakers in series to the integrated amplifier because it will result in poor sound quality. Do not connect speakers rated at less than 4Ω.

Applications: The Sonos Amp offers flexibility and can be used in a variety of applications. Connect your favorite bookshelf, floorstanding, in-wall, or in-ceiling speakers to the Amp and stream all your favorite music.

  • Connect the Sonos Amp to a pair of loudspeakers to listen to network audio and a connected line-level source.
  • Use the Amp to add stereo sound to your TV through a HDMI ARC connection and a pair of loudspeakers.
  • Use the Sonos Amp with a pair of loudspeakers to add surround sound, if you already have a Sonos home theater speaker - such as the Playbar / Playbase / Beam, or another Amp) connected to your TV.

HDMI ARC: The Sonos Amp is equipped one HDMI ARC output to connect the integrated amplifier to your TV's HDMI ARC input. The Amp's HDMI ARC output allows audio from your TV to be sent to the integrated amplifier. The HDMI ARC output supports Dolby Digital (up to 5.1ch) and 2ch PCM. Some televisions will only pass 2ch PCM through the ARC-enabled HDMI input from devices connected to the TV via HDMI or analog, and will only pass Dolby Digital via the TV's built-in tuner, network apps, or USB. Audio from your TV can be played back just on the Sonos Amp or in any zone of your Sonos multiroom audio system.

Note: If your TV does not have a HDMI ARC input, but does have an optical (toslink) digital output, an HDMI-to-optical digital adapter (sold separately) is available directly from Sonos. The HDMI-to-optical digital adapter features a female HDMI connector on one end to slip on to a HDMI cable's male connector and a male optical (toslink) connector on the other end to plug into your TV's optical digital output (you cannot use a dedicated optical digital cable with the Sonos Amp). This type of connection will still support 5.1ch Dolby Digital and 2ch PCM.

Analog Input: The Sonos Amp is equipped with a set of stereo analog RCA inputs for connecting an external line-level audio device, such as a CD or SACD player (sold separately). You can also connect a turntable which features a built-in phono-preamp or a turntable with an external phono-preamp (all sold separately). Audio from the external source can be played back just on the Sonos Amp or in any zone of your Sonos multiroom audio system.

Custom Speaker Outputs: A pair of binding-post terminals provide connection of your speaker wire (up to 10AWG). The binding-posts are removable and pull-out to expose speaker terminals that will accept banana plugs (single only).

Mono-Sub Out: The integrated amplifier features a mono-RCA output for connecting a powered subwoofer (sold separately) with an LFE or line-level input. The unit will detect when a cable is connected to the subwoofer output and adjust the low-pass crossover frequency automatically.

Front-Panel Controls: There are touch-sensitive controls across the front-panel of the Sonos Amp. These controls included Volume Up/Down, Play/Pause, and Previous/Next Track. There is also an IR (infrared) sensor on the front-panel that receives signals sent by a programmable IR remote control (not included and sold separately).

Mounting Options: You can place the Sonos Amp just about anywhere - in an electronics rack, on a shelf, on a credenza with your TV, or wall-mounted using a proprietary bracket (sold separately). On a shelf or table-top, mount the integrated amplifier horizontally with a least 3" of clearance around the unit. The Amp will also work perfectly in a rack-mount system. Two Amps will fit side by side in a 2U rack shelf, while four Amps will fit in a 3U rack shelf (side by side & stacked). Using a proprietary wall-mount bracket the Sonos Amp hangs vertically on the wall.

AC Power: The Sonos Amp comes with a detachable 6.5' AC power cord that will plug into the back of the integrated amplifier and into and AC power outlet or surge protector (sold separately).

Network Multiroom Audio

Sonos Multiroom Eco-System: The Amp is part of the Sonos wireless multiroom audio eco-system consisting of a family of wireless network speakers, players, and amplifiers. Start with a single Sonos product and add more Sonos products over time - including speakers, soundbars, players, and amplifiers (all sold separately - see Accessories Tab). With multiple zones, you can play the same or different songs in different rooms of your home. Up to 32 Sonos devices can be connected in one system.

Two Ways to Connect Wirelessly: Sonos brings great sounding music wirelessly to any room in your house, without a big wiring project through SonosNet or WiFi.

  • SonosNet Wireless Mesh Network: Sonos can utilize its own SonosNet proprietary wireless mesh network technology to provides superior wireless range for whole-house coverage, ensure synchronous music playback, and avoid sources of wireless interference. The transmitting range of the Sonos wireless system is approximately 100', depending upon your home's layout. In addition to the Sonos Amp, you will need a Sonos Boost (sold separately) connected to your network router/modem via a Ethernet cable.
  • WiFi Wireless Network: Sonos can also operate over your home's existing WiFi network (802.11 b/g/n; 2.4GHz). Because you are connecting wirelessly to your home's existing WiFi network, you do not need to hardwire a Sonos Boost to your router/modem. The Sonos system's wireless range will be dependent on your home's existing WiFi network.
  • You cannot connect the Sonos system via both the SonosNet proprietary mesh network and WiFi; you will need to choose one. Sonos recommends using its proprietary SonosNet wireless mesh network over WiFi when applicable.
  • The Sonos proprietary mesh network will provide a more secure wireless connection with fewer interruptions for optimum performance.
  • WiFi is subject to greater interference from other WiFi and 2.4GHz devices on your network. WiFi connectivity is not compatible with 5GHz (you will have to use the Sonos wireless mesh network in this case).

Ethernet Port (10/100 Mbps): In addition to built-in WiFi, the Sonos Amp is equipped with two Ethernet ports (10/100 Mbps). Use it to wire directly to your router to operate Sonos if WiFi is unstable, or use the Ethernet port to provide Internet accessibility to non-wireless devices if you're using a SonosNET Boost setup. The second Ethernet port can be used to daisy-chain one Sonos Amp to another in a rack-mount system.

Sonos Controller App: Sonos allows you to control playback functions, search features, and multiroom audio distribution through the Sonos Controller app (for Apple iOS 10.0+ and Android OS 5.0+) or the Sonos Controller software (for Windows PC (7-up) and Mac OS X 10.10-up) - letting you control the entire Sonos eco-system from your compatible smartphone, tablet, laptop, or computer. The new navigation bar (My Sonos, Rooms, Browse, Search and More) at the bottom of the app makes finding what you're looking for effortless and moving between music quicker than ever. 

  • My Sonos: Organize your music with the My Sonos tab. It's the simplest way to combine and access all the music you love. Bringing together in one simple screen all your favorite songs, playlists, albums, podcasts and radio stations from across your different music services.
  • Now Playing: The Now Playing screen features album art and basic playback controls. For a deeper look into the music you're listening to, the "Info View" screen gives you artist bios, album reviews and concert listings. See related artist suggestions to discover a new band for your queue. You can also add to your playlists, delete songs from your library, and share tracks to Twitter or Facebook.
  • Rooms: You can choose to play different songs in different rooms, choose to group all rooms together to hear the same music throughout your home, or choose to group only certain rooms together for music playback. You can also crank up the volume for each room individually or together.
  • Browse & Search: Browse your music services, favorites, internet radio, personal music library and playlists. You can browse your music content by Album, Artist, Song, or Playlist. You can even search across all of your music services and files simultaneously, so you can find the music you love instantly.
  • More: Provides personalized & custom settings for your Sonos system. Adjust and audio settings like bass, treble, balance, and loudness for each room location.
Note: The Sonos device, Apple iOS/Android device, Windows PC, and/or Mac computer must be connected to the same wireless network.

Music Services & Libraries: Sonos gives you access to popular online music services and internet radio stations, and well as music libraries stored on your computer or NAS drive.

  • Online Music Services: Sonos works seamlessly with Apple Music, Amazon Music, TIDAL, Pandora, Spotify, SiriusXM, Google Play Music, TuneIn, iHeartRadio, Rhapsody, Deezer, SoundCloud, and more; plus downloads from any service offering DRM-free tracks. (Service availability varies by region.) Click here for the latest online music services (some online services require a paid subscription).
  • Music Libraries: Sonos supports playback of music from any computer or network-attached storage (NAS) device on your home network where you have shared music folders. Sonos can play music stored on up to 16 PCs, Macs or NAS (Network Attached Storage) devices on your home network, supporting the most popular audio formats. Sonos indexes your music folders so you can view your music collection by categories (such as artists, albums, composers, genres, or tracks). Sonos supports the following audio file formats - MP3 (compressed), WMA (compressed), AAC (MPEG4), Ogg Vorbis, Audible (format 4), Apple Lossless, FLAC (lossless), WAV (uncompressed), and AIFF (uncompressed).

AirPlay 2: AirPlay 2 is an advanced and easy-to-use wireless multiroom audio platform for iTunes, Apple Music, and other Apple iOS apps. With AirPlay 2 you can play any sound from your Apple iOS device (running iOS 11.4 or later) or Mac computer (running OS X 10.13.2) on the Sonos Amp, One, Play:5, Beam, and other compatible AirPlay 2 products throughout your home. You will also be able to ask Siri-enabled devices (like your Apple iPhone, iPad, or Watch) to control playback of your Apple Music on compatible Sonos speakers. You can even watch videos and movies from YouTube and Netflix on your compatible Apple iOS device or Mac computer with perfectly synced audio on a Sonos One, Play:5, or Beam speaker. You can choose to play audio in one room, play the same audio in grouped rooms, or play the same audio in every room.

Note: Even though the Play:1, Play:3, Playbar, and other Sonos products are not AirPlay 2 compatible, you can still group these Sonos speakers with an AirPlay 2 compatible player (like the Sonos One, Play:5, or Beam) to unlock AirPlay for your entire system.

Optional Voice Control: Through a free network software update you'll be able to control your Sonos system through any Alexa or Google Assistant enabled device (including the Sonos One, Amazon Echo, and Google Home - all sold separately). Specific control functions will vary by digital voice assistant.

  • Amazon Alexa: You can ask Alexa to play music on a specific Sonos device in an specific room of your home from these featured music services (Apple Music, Amazon Music, TuneIn, Pandora, iHeartRadio, SiriusXM, & Spotify). Using the Alexa app, you can group your Sonos products and your Alexa-enabled devices together. This makes it easier for Alexa to control your Sonos products based on which room or area they are in. You can pause, resume, and skip songs, as well as change the volume with all Sonos compatible online music services.
  • Google Assistant: You can ask Google to play music on a specific Sonos device in an specific room of your home from these featured music services (Google Play, Spotify, YouTube Music, Pandora, Deezer, Tidal, TuneIn, and iHeartRadio). You can pause, resume, and skip songs, as well as change the volume with all Sonos compatible online music services.
  • You can only configure your Sonos system to work with one digital voice assisant; choose either Alexa or Google Assistant (you cannot use both). You will need to search and enable the Sonos skill from the Alexa or Google Home app on your mobile device or computer. Your Sonos equipment and Amazon Alexa-enabled devices must be on the same wireless network.
  • Sonos and Alexa or Google Assistant work together using a single Amazon or Google account. If you have a second Sonos system in another location, you'll need to use a second Amazon or Google account if you'd like to use Alexa. An Amazon or Google account can only be in use on one Sonos system at a time.
  • Click here for more information regarding Amazon Alexa on Sonos. Click here for more information regarding Google Assistant on Sonos.

Home Network Requirements: To access Internet music services, Internet radio, and any digital music stored on your computer or Network-Attached Storage (NAS) device, your home network must meet the following requirements:

  • High-speed DSL/Cable modem, or fiber-to-the-home broadband connection for proper playback of Internet-based music services. If your Internet service provider only offers Satellite Internet access, you may experience playback issues due to fluctuation in download rates.
  • If your modem is not a modem/router combination and you want to take advantage of Sonos' automatic online updates, or stream music from an Internet-based music service, you must install a wireless router in your home network. If you don't have a wireless router, you will need to purchase and install one before setting up your system.
  • The Sonos Controller app (for Apple iOS 10.0+ and Android OS 5.0+) is required for system setup. Initial setup is not possible through the Sonos Controller software (for Windows PC (7-up) and Mac OS X 10.10-up).
  • Connect at least one Sonos component to your home network router using an Ethernet cable, and then you can add other Sonos components wirelessly. Or setup your Sonos component wirelessly via WiFi without any hardwire connection.
  • For best results, you should connect the computer or NAS drive that contains your personal music library collection to your home network router using an Ethernet cable.
  • Make sure all of your Sonos components have the latest software update installed.
Note: Although Sonos is compatible with most networking equipment, some network devices are incompatible. Usually when networking hardware does not work with Sonos, it's because it lacks support for the network protocols that Sonos uses to operate, like UPnP, STP, and SMB/CIFS.

Automatic Updates: The Sonos Amp supports free automatic software updates so you will always have the newest features and music services to enjoy. Simply register the Amp and Sonos will automatically notify you when software updates are available through Sonos Controller app. By simply pressing one button your system updates itself.

Crutchfield asked: Why did you buy this?
Builder [ M  Jun 21, 2019 ]
I already have 11 other zones. [ tim  Jun 06, 2019 ]
This is a perfect companion for outdoor speakers to guarantee summertime fun! Whether enjoying drinks, a BBQ with friends, or just soaking in the sun by the pool, Sonos provides the right music to set the mood. [ Jeffery  Apr 13, 2019 ]
I initially purchased a Sonos Connect AMP to run 4 - Klipsch AW650 outdoor speakers, the connect AMP couldn't handle them past about 50% volume, the AMP has the power to drive these just fine. They sound amazing. [ Jason  Mar 18, 2019 ]
Need to power outdoor speakers - pool season right around the corner! [ Mark  Mar 02, 2019 ]
More power than the Connect Amp [ Jonathan  Feb 19, 2019 ]
To add to my sonos system and to drive an excellent set of speakers I already own. [ David  Feb 09, 2019 ]

2 questions already asked

Can I connect two rear speakers and wired subwoofer to this to go in conjunction with a Sonos PlayBar?
[ Bobby  Sep 01, 2019 ]
2 answers
Rears yes, wired Sub no. You need to use the Sonos Sub.
[ Dawn  Sep 02, 2019 ]
Yes, I have 2 wired ceiling speakers and wired subwoofer connected to my Sonos Amp and use with my Sonos PlayBase/2 Sonos 1s. Downside is you have to use the Sonos phone app to control the volume of all. This is easily solved by getting an iPort remote control that control volume of all speakers.
[ JOHN D  Sep 02, 2019 ]
does Sonos Amp work with in-ceiling speakers from Klipsch or other brands?
[ rk2009  Apr 18, 2019 ]
7 answers
Yes, it should work with a wide variety of speakers. You will have to connect them with banana plugs.
[ Alexandros  Apr 30, 2019 ]
Yes I believe it will. It has universal speaker connections in the back, like any amp. So any speakers taking standard two-wire connections should work fine. I have both a set of Yamaha indoor speakers as well as a set of Bose outdoor set connected to mine.
[ ANIL  Apr 30, 2019 ]
I expect the amp would work, but I no longer have the Sonos, because after about two weeks it failed. I was listening when suddenly I heard a big bank, which sounded like a gunshot. The amp was dead, and I sent it back.
[ David  Apr 29, 2019 ]
The amp is is like any other amp when connecting speakers. I used in ceiling FOCAL. The new Sonos Amp is far superior to their previous amp with more clarity and power.
[ Gregory  Apr 29, 2019 ]
It works with any speakers due to the fact that they are hard wired to the unit. It will not speak to other Bluetooth speakers that I'm aware of.
[ Ricardo  Apr 29, 2019 ]
It should work with any 8 ohm (non-powered) speaker.
[ Don  Apr 29, 2019 ]
Yes I've hooked up 2 pairs of Polk Rc80is to this amp. Sounds great
[ KARI  Apr 29, 2019 ]
