TV stand placement
Wall mount
You can secure the soundbar to a wall with a compatible wall mount. We recommend the
custom-designed Sonos Arc Wall Mount. See Sonos wall mount.
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.
Connect the cables
Before you start
1Connect 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).
2Connect the HDMI cable (included) to
the soundbar's HDMI port.
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.
3Connect the HDMI cable to your TV: TV with ARC/eARC port
Optical adapter (if needed)
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).
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.

Note: WiFi is turned off for Era 100 and
Era 300 when you connect a Sonos
Combo Adapter using the Ethernet cable.
EQ
Sonos products ship with preset
equalization settings. You can change the
sound settings (bass, treble, or loudness)
to suit your personal preferences. Learn

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

indicates when the volume is muted, and
signals errors. Learn more
Note: If the light is distracting, you can
turn it off in Settings.

prevent a child or curious pet from
accidentally adjusting playback or volume.

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.
Line-In
(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. (Autoplay is
disabled by default.)
Trueplay™
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.
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.

works with your TV.

a group, you can adjust this setting. Learn

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,

room’s settings.

them toward the seating area.

Wall mount bracket
Positioning guide (don't discard—it may look like packing material)
2 knobs
6 wall anchors
6 screws
1If your TV is wall-mounted, place the
positioning guide against the wall,
aligning the top edge with the bottom
of your TV. There should be 5.5"
(140mm) between the top of the wall
mount bracket and the TV.
2Mark the screw locations and remove
the guide.
3If you’re using the included wall
anchors, use a 5/16" drill bit to drill the
pilot holes and then insert the wall
anchors. Don’t use the anchors if
you’re drilling into wood or plastic.
4Position the wall mount bracket over
the marked screw locations, using a
level to confirm accuracy. Use a
Phillips-head screwdriver or a power
drill to screw the bracket to the wall,
making sure the arrows in the center
are pointing up.
5Screw the 2 knobs into the back of
the soundbar until they are fully
tightened.
6Connect the power and HDMI cables
to the back of the soundbar.
Note: If you’re connecting the cables
to the TV at this time, be sure to plug

knobs fit into the slots on the wall
bracket. Make sure the touch controls
are facing up and the soundbar is fully
seated.
