Why you will love it

Power for passive speakers

Sonos says Amp packs 125 watts per channel, so you can power outdoor speakers and listen at higher volumes with clear, undistorted sound. It can run stereo or dual mono.

Speaker connections are custom-designed banana plugs that can be swapped for standard diameter banana plugs. A pair of banana plugs is included.

Add it to your TV

Connect Amp to your TV's HDMI eARC/ARC port for stereo sound for shows, movies and games. Sonos says you can then wirelessly add a pair of Sonos surrounds.

If your TV has an optical output only, Sonos says to use its Optical Audio Adapter, which is sold separately. Sonos lists Stereo PCM, Dolby Digital and DTS Digital Surround as home theatre audio formats.

Connect your own gear

Amp has a line-in for a CD player or turntable and a subwoofer output with an auto-detecting RCA connection and a user-adjustable 50 to 110 Hz crossover.

Sonos says you can adjust bass, treble and loudness in the Sonos app. Trueplay can tune the room for supported Sonos Architectural by Sonance speakers, with an iOS device.

Control your way

Control Amp with the Sonos app, with touch controls on the unit, or with Apple AirPlay 2 from an iPhone, iPad or Mac. Sonos says you can add a voice-enabled speaker such as Sonos Play or Era 100 for hands-free control.

Sonos lists partner integrations for smart home control, including Lutron, Control4, Alarm.com, RTI and URC.

Built to rack mount

Sonos says the rack-mountable design has an advanced heatsink for optimised airflow and heat management.

It has dual 10/100 Ethernet ports and a quad core 1.3 GHz A7 processor.

Is it right for you?

A great fit if you…

Have passive speakers, including built-in or outdoor speakers, and want to stream to them
Want to connect a TV by HDMI ARC
Want to add a turntable or CD player and join a Sonos multiroom system

Worth knowing

It needs passive or wired speakers connected to produce sound
HDMI eARC/ARC is the TV connection; older TVs with optical output only need the separate Sonos Optical Audio Adapter
It needs WiFi and the Sonos app
When two Amps are used in a home theatre setup, Sonos says the Amp powering the surrounds cannot be wired to the network unless the Amp powering the front speakers is also wired

Build your system

Connect speakers and a TV to Amp, then add more Sonos products around the home.

Speakers: Connect bookshelf speakers, floor-standing speakers, in-ceiling speakers or outdoor speakers.
Streamer for your own amplifier: To add Sonos streaming to an existing stereo see the Sonos Port network streamer.
Voice-enabled speaker: Add the Sonos Era 100 for hands-free control.
Bass: Add a Sonos Sub Mini, or browse the Sonos wireless audio range.
