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 or on a shelf.
Rack mounted
- Amp mounts in any electronics rack.
- Place two Amps side by side in a 2U rack.
- Place four Amps in a 3U rack.
- When using Amp in a rack mount, we recommend connecting each product directly to a networking switch and disabling WiFi to conserve power and reduce waste heat.
- Do not connect more than four Sonos products via Ethernet to each other in a row or you may experience network instability. Learn more
Placed on a shelf
- Keep 3" / 50 mm (minimum) clearance on all sides and top.
- Place horizontally on a stable and level surface
- Don’t block the touch controls on the front of Amp.
- If using with a TV, don't block the IR sensor, and keep 3" / 50 mm from the TV.
Connect the cables
1 | Make sure the speakers you use 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 a TV, use an HDMI cable to connect from Amp's 's HDMI port to the TV.
When connected, Amp creates two front audio channels and plays TV sound through your 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 (some products, like Era 100 and Era 300, require a line-in adapter—sold separately).
Then in the Sonos app, go to 
> Line-In and select the source to start playback. Learn more
Note: Allow Line-In must be enabled in Global Settings[LINK] on the Dashboard. Learn more
Stereo to mono
Amp plays audio in stereo by default. You can change the sound settings for the zone associated with Amp so it plays in two mono channels when playing music.
To change your setting, go to Settings 
and select the room that you want to modify. Then go to Sound, select Stereo/Mono, and choose an option.
