Connector Panel
| 1 - AC power (mains) input | Use only the supplied power cord (using a third-party power cord will void your warranty). |
| 2 - Bluetooth button |
|
| 3 - Universal microphone switch | Toggle to turn all product microphones on or off. When the switch is off (down), the microphones are disabled so microphone-enabled features like Trueplay quick tuning and voice 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.) Note: To use voice services, both the microphone switch and the voice services indicator light must be 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. |
Sonos Era 300 Placement tips
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:
- 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” (20.32 cm) on each side of the speaker.
- When using Era 300 speakers as surrounds, leave at least 8" (20.32 cm) clearance around the 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.
Bluetooth Pairing
- Turn Bluetooth on in your device settings.
- 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.
- Choose Sonos Era 300 from the list of available devices in your Bluetooth settings. Your mobile device will automatically connect next time.
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.
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.
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.
- 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).
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.
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 
> System, choose a room, and select Trueplay.
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. Best choice for larger rooms. If VoiceOver is enabled on your iOS device, Advanced tuning isn’t available. Turn it off in your device settings before tuning your speakers.
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.
- 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.
- Go to > System.
- Select one of the speakers you want to use in the stereo pair, then choose Set Up Stereo Pair to get started.
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.
- Place each surround speaker about 10 ft from your favorite listening position, angling them toward the seating area.
- Go to > System.
- 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. |
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 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 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. |
| EQ | Sonos products ship with preset equalization settings. You can change the sound settings (bass, treble, balance, or loudness) to suit your personal preferences. |
| Trueplay | Trueplay adapts the sound for your surroundings and content. Portable products can tune themselves automatically. |
| Volume Limit | You can set a maximum volume for each room. |
| Status Light | Displays the speaker’s connection to WiFi, indicates when the volume is muted, and signals errors. 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:
