Connector panel


HDMI port

Use to connect Sonos Arc to your TV.


Join button

Press to connect during setup.


Ethernet port

Use an Ethernet cable if you want to connect to a router, computer, or network-attached storage (NAS) device (optional).


AC power (mains) input

Use only the supplied power cord (using a third-party power cord will void your warranty).

Note: Insert the power cord firmly until it is flush with the speaker.

Select a location

You can wall mount Arc below your TV or place it in or on a TV stand.

TV stand placement

  • Place horizontally on a stable and level surface.
  • Keep 4" (102mm) space (minimum) between the top of the soundbar and the bottom of your TV (if placing soundbar below the TV).
  • Don't place vertically or on its side.
  • Make sure the touch controls are facing up.

Wall mount

You can secure the soundbar to a wall with a compatible wall mount. We recommend the custom-designed Sonos Arc Wall Mount (sold separately). See wall mount.

Connect the cables

Before you start

  • Disconnect existing home theater or surround sound equipment from your TV.
  • Connect any external devices, like a cable box or DVD player, directly to your TV.
  • Turn your TV on.

Connect the power cord and plug in the soundbar.

Note: Use only the supplied power cord (using a third-party power cord will void your warranty).


Connect the HDMI cable (included) to the soundbar's HDMI port.


Connect the HDMI cable to your TV:

  • If your TV has an HDMI ARC (or eARC) port, connect the HDMI cable to it.
    (HDMI ARC is a special port that looks like a standard HDMI port—it may be on the back or side of your TV. The ports look similar, but the ARC port will be labeled ARC, eARC, or ARC/eARC. If you connect the Sonos soundbar to a standard HDMI port instead, you won’t hear any sound).
  • If your TV doesn’t have an HDMI ARC or eARC port, you'll need to use the optical adapter:
    • Remove the protective cap from the optical adapter, then attach the optical adapter to the HDMI cable.
    • Connect the optical adapter to your TV’s optical digital OUT port.
      (The TV's optical adapter’s port is “D-shaped”—make sure the connector aligns correctly into the port. Inserting the adapter incorrectly may damage the cable).

Voice services

Use your voice to control your Sonos system with any voice-enabled Sonos product—play and control content, turn the volume up or down, and more.

  • Sonos Voice Control: control your whole Sonos system with hands-free ease and unmatched privacy. Sonos Voice Control comes ready to use—it only takes a few seconds to add when you set up your speakers. More information
  • Amazon Alexa: you’ll need the Sonos app and the Alexa app with the Sonos skill enabled. You’ll make some changes in both apps during setup. Learn more
  • Google Assistant: you’ll need the Sonos app and the Google Assistant app. You’ll make some changes in both apps during setup. Learn more
  • Siri: you’ll need the Apple Home app. Add your AirPlay2-compatible Sonos speakers to the Apple Home app and then use an iPhone, iPad, or Apple TV to ask Siri to play music (currently limited to Apple Music). Learn more

Note: Voice control isn’t supported in every country yet—this feature will be available as soon as Sonos and a voice service launch together in your region.

Microphone on/off

The microphone is used for voice control and for microphone-dependent features like Trueplay tuning. Press to turn the microphone on or off—the microphone LED light will let you know when your voice assistant is listening.

When the microphone light is on:

  • If you set up a voice service, voice control is on and ready to respond.
  • Microphone-dependent features like Trueplay are available.

When the microphone light is off:

  • If you set up a voice service, voice control is off.
  • Microphone-dependent features like Trueplay are unavailable.


Every room is different. Trueplay tuning measures how sound reflects off walls, furnishings, and other surfaces in a room, then fine tunes your Sonos speaker to make sure it sounds great no matter where you've placed it.

Trueplay works on iOS mobile devices running iOS 8 or later. During tuning, you'll move around the room holding your mobile device.

  1. Select > System, and pick the room you want to tune.
  2. Choose Trueplay Tuning to get started.

Auto Trueplay

Portable Sonos products like Sonos Roam and Move can tune themselves automatically. Auto Trueplay uses your speaker’s microphone to detect the environment and make periodic tuning adjustments so you get great sound wherever your speaker is and whatever you're listening to.

Go to > System, and select your portable speaker to turn on auto Trueplay.

Product settings

You can customize Sonos products for your surroundings. Go to > System and select a product.

Room Name

If you move your speaker to a new room, you can change its name in Settings.

Turn off WiFi

(not available for Sonos Era 100, Era 300, or portable products)

You can turn off your speaker’s WiFi when it’s connected to your network with an Ethernet cable. This reduces power consumption and can improve connectivity for wired speakers.

For products like Amp and Port, turning off WiFi can reduce the internal temperature when they’re placed in a rack or stacked. Learn more

Note: WiFi is turned off for Era 100 and Era 300 when you connect a Sonos Combo Adapter using the Ethernet cable.


Sonos products ship with preset equalization settings. You can change the sound settings (bass, treble, or loudness) to suit your personal preferences. Learn more


Trueplay adapts the sound for your surroundings and content. Portable products can tune themselves automatically. Learn more

Volume Limit

You can set a maximum volume for each room. Learn more

Status Light

Displays the speaker’s connection to WiFi, indicates when the volume is muted, and signals errors. Learn more

Note: If the light is distracting, you can turn it off in Settings.

Touch Controls

You can disable the touch control on your speaker. You may want to do this to prevent a child or curious pet from accidentally adjusting playback or volume. Learn more

Battery Saver

(portable products only)

To save battery life, you can set your portable speaker to power off automatically instead of going to sleep. It won't appear in the Sonos app until it’s powered back on.


(Sonos products with line-in capability)

When a projector, turntable, stereo, or other audio device is connected to a Sonos product, you can adjust these line-in settings:

  • Source name: Choose a name for the line-in device.
  • Source level: Adjust the line-in source level if you find the default volume setting is too quiet or distorted.
  • Audio Delay: Add a delay between the line-in source and Sonos to reduce the chance of audio issues occurring when you're playing line-in audio on grouped speakers.
  • Autoplay: Choose a room if you want line-in audio to start playing automatically when Sonos detects a signal on the line-in port.

Home theater

Sonos products for your TV provide full-theater sound and play music too. Create a home theater system by adding a pair of rear surrounds and a Sub.

Home theater settings

TV Dialog Sync

If the TV audio is out of sync with the video, you can adjust the audio delay (lip sync) in your room’s settings. Learn more

If you notice audio issues when playing to a group, you can adjust this setting. Learn more

TV Autoplay

TV Autoplay—if music or other content is playing when you turn on your TV, the audio automatically switches to TV audio (default). If you don’t want this to happen, turn off TV Autoplay in your room’s settings.

Ungroup on Autoplay—if your home theater speaker is grouped with other products when you turn on the TV, it automatically drops from the group (default). If you don’t want this to happen, turn off Ungroup on Autoplay in your room’s settings.

Night sound

Set up surrounds

It’s easy to turn two Sonos speakers (same model), or a Sonos Amp and your favorite non-Sonos speakers, into separate right and left channels for your home theater.

  1. Place each surround speaker about 10 ft from your favorite listening position, angling them toward the seating area.
  2. Go to > System.
  3. Select a room with a soundbar and choose Add Surrounds to get started.

Note: If you group the rooms or create a stereo pair instead, you won't have surround sound.
