services are unavailable.
When the switch is on (up),
microphone-enabled features like
Trueplay are available. (Voice
services are available if the voice
services indicator light on top of
the product is also on.)
4 USB-C port The USB-C port is designed for line-in
and Ethernet connections using the
Sonos Line-In Adapter or Combo
Adapter (sold separately). It's not a
power source for the speaker and
shouldn't be used to charge other
devices.
Ethernet: Use the Sonos Combo
Adapter and an Ethernet cable to
connect Era 300 directly to your
router if you want to hardwire your
speaker (helpful if your WiFi is
unstable).
Line-in: Use either the Sonos
Line-In Adapter or Combo Adapter
to connect your turntable, CD
player, projector, or other device.
Select a location
Trueplay tuning will balance the sound for wherever you place Era 300, but for the speaker to
project sound most effectively, here are a few guidelines:
Bluetooth pairing
1. Turn Bluetooth on in your device settings.
2. Press and hold the Bluetooth button on the back on the speaker until you hear a tone,
then release. The status light blinks blue when the speaker is ready to pair.
3. Choose Sonos Era 300 from the list of available devices in your Bluetooth settings. Your
mobile device will automatically connect next time.
Era 300 should be placed indoors and have approximately two ft (.61 m) of overhead
clearance for optimal sound quality. Placement in an enclosed space like a bookshelf is
not recommended as this could impact dispersion and playback clarity.
If you are mounting Era 300 within 2 ft (.61 m) of a ceiling, place it upside down for the
best sound.
When Era 300 is placed next to a wall or on a shelf, leave at least 1" (2.5 cm) clearance in
back and 8” (203 mm) on each side of the speaker.
When using Era 300 speakers as surrounds, leave at least 8" (203 mm) clearance around
the back and sides of each speaker.
Traditional stereo setups often have an ideal place to sit in a room for the best listening
experience, but with Era 300 the sound is sent in all directions so you'll experience rich
detail no matter where you’re seated.
Note: Don’t position Era 300 vertically or at a steep angle or the audio will stop.
Microphone on/off
There are two ways to control the microphones on Era 300:
A universal microphone switch on the back turns all microphones on and off.
A voice services button on top turns voice services on and off without affecting the
microphones needed for Trueplay and other microphone-enabled features.
When both are on, voice control and all microphone-enabled features are available.
When both are off, voice control and all microphone-enabled features are unavailable.
When the universal microphone switch is on and the voice services light is off, Trueplay
and other microphone-enabled features are available but voice control is off.
Trueplay™
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
place it.
During setup, choose the Trueplay option that works best for you and your space. To retune
later, go to Settings > System, choose a room, and select Trueplay.
Note: If VoiceOver is enabled on your iOS device, Trueplay tuning isn’t available. Turn it off in
your device settings before tuning your speakers.
Advanced Tuning
Advanced tuning is custom and precise. It takes about 5 minutes and uses the microphone on
an iOS device (running iOS 8 or later) so you'll move around the room while the sound is fine
tuned for your space.
Note: Advanced tuning is the best choice for large rooms (open concept spaces may
experience less precise tuning).
Quick Tuning
Quick tuning is fast, effortless, and accessible. It takes about a minute and uses the
microphone on your Sonos product to detect the environment so there's no need to move
around the room during tuning.
Note: Quick Tuning is available for both iOS and Android, and is a good choice for smaller
rooms, or spaces where it's difficult to move easily.
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.
Set up stereo pair
Pair two Sonos speakers in the same room for an even wider, stereo experience. One
speaker serves as the left channel and one serves as the right channel.
Note: The Sonos speakers in a stereo pair must be the same type.
1. Place the speakers 8 to 10 feet apart. Your favorite listening position should be 8 to 12
feet from the paired speakers—less distance increases bass, more distance improves
stereo imaging.
2. Go to > System.
3. Select one of the speakers you want to use in the stereo pair, then choose Set Up Stereo
Pair to get started.
Learn more
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.

Surround audio settings
During setup, surround sound is optimized for your room. These settings are adjustable:
Surrounds Turn surround sound On or Off.
TV Level Adjust surround volume for TV audio.
Music Level Adjust surround volume for music.
Music Playback
Ambient (subtle) or Full (louder, full
range). Doesn't apply to Dolby Atmos
Music playback.
Line-in
Connect an audio device, like a projector, CD player, or turntable (with a built-in phono
preamp), to any Sonos product that has a line-in port (Era 300, Era 100, Amp, Port, or Five).
Then go to > Line-In to select the source and start playback.
Note: Era 300 and Era 100 require a Sonos Line-In or Combo Adapter (sold separately).
Other products may require a different type of line-in adapter depending on your audio source.

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

Battery Saver
(for 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
(for 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:

signal on the line-in port. (Autoplay is
disabled by default.)
