Amp
Overview
Overview
Power your passive speakers, create your dream smart home, and enjoy endless possibilities for multiroom listening.
- Amp features a built-in state-of-the-art digital amplifier that can power large or small speakers so you can enjoy superior audio in any room.
- Works with either Sonos S2 or Sonos S1 (for Android and iOS).
Play music through your favorite speakers
- Connect your favorite bookshelf, floor-standing, in-wall, or in-ceiling speakers to Amp to stream all the music you love.
- Connect a turntable, stereo, or portable audio device and play the sound on any Sonos speaker.
Enhance your TV sound
Connect Amp to your TV to create the ultimate entertainment system.
- Use Amp and a pair of 3rd-party speakers to create two front audio channels.
- Use Amp with third-party speakers to add surround sound if you already have a Sonos home theater speaker (Arc, Arc SL, Beam, or another Amp) connected to your TV.
(For even deeper sound, add a Sonos Sub or connect a third-party subwoofer.)
See Setup when you’re ready to add Amp to your Sonos system.

Connector panel
1 | HDMI ARC | Use an HDMI cable to connect Amp to your TV’s HDMI ARC port. |
2 | Ethernet ports | Use an Ethernet cable if you want to connect to a router, computer, or network-attached storage (NAS) device (optional). |
3 | Join button | Press to connect during setup. |
4 | AC power (Mains) port | Use only the supplied power cord (using a third-party power cord will void your warranty). |
5 | Analog audio in | Use a standard RCA audio cable (included) to connect Amp's analog audio inputs to the outputs on another device, like a pre-amplified turntable or portable music player. |
6 | Subwoofer output | Connect a powered subwoofer to this output using a standard RCA cable. The system will detect when a cable is connected to the subwoofer output and adjust the crossover frequency automatically. Note: If you disconnect your subwoofer, make sure to also disconnect the subwoofer’s cable from the Amp output. |
7 | Speaker terminals | Use high-quality speaker wire to connect your speakers to Amp. |
Select a location
You can place Amp just about anywhere—in an electronics rack, on a shelf, or on a credenza with your TV.
Rack mounted
- Amp mounts perfectly in any electronics rack.
- Place two Amps side by side in a 2U rack.
- Place four Amps in a 3U rack.
Placed on a credenza
- Place horizontally on a stable and level surface at least 3 in / 50 mm from the TV.
- Don’t block the TV’s IR sensor.
- If put on a shelf, place at the front and keep 3" (minimum) clearance on all sides.
- Don’t block the front of Amp so you can reach the touch controls.
Connect the cables
1 | Make sure your speakers are compatible with Amp:
| |
2 | Remove the cap from the banana plug to reveal the connection hole. | |
3 | Insert the stripped end of the speaker wire into the hole, then put the cap back on the banana plug to secure the connection. Note: Connect the red (+) and black (-) terminals from each speaker to the corresponding banana plugs and terminals on Amp. Mismatching of polarities will result in weak central sound and a distorted sense of sound direction. | |
4 | Insert the banana plug into the proper speaker terminal on the back of Amp. | |
5 | Repeat to install the other speaker wires. | |
6 | Connect the power cord and plug in Amp. | |
7 | If you're connecting Amp to your TV, use an HDMI cable to connect from Amp's 's HDMI port to your TV.
When connected, Amp creates two front audio channels and plays your TV sound through your favorite non-Sonos speakers. |
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.
Stereo to mono
Amp plays audio in stereo by default. You can change the sound settings for the room associated with the Port so it plays in two mono channels when playing music.
- Go to Settings > System, and select Amp.
- Select Advanced Audio > Stereo/Mono, then choose an option.
