HDMI ARC

Use an HDMI cable to connect Amp to your TV’s HDMI ARC port.

Join button

Press to connect during setup.

AC power (mains) port

Use only the supplied power cord (using a third-party power cord will void your warranty).

Note:Insert the power cord firmly.

Analog audio in

Use a standard RCA audio cable to connect Amp’s analog audio inputs to the audio outputs from a separate audio component, such as a turntable or a portable music player.

Ethernet ports (2)

Use an Ethernet cable if you want to connect to a router, computer, or network-attached storage (NAS) device (optional).

Subwoofer output

Note:If you disconnect your subwoofer, make sure to also disconnect the subwoofer’s cable from the Amp 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.

Speaker terminals

Use high-quality speaker wire to connect your speakers to Amp.

 

What can you do with Amp?

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 music player and play the sound on any Sonos speaker.

Enhance your TV sound

Connect Amp to your TV to create the ultimate entertainment system.

(For even deeper sound, add a Sonos Sub or connect a third-party subwoofer.)

See Connect Amp to your TV for setup information.

Select a location

You can place Amp just about anywhere— in an electronics rack, on a shelf, or on a credenza with your TV.

Connect the cables

Attach desired speakers

Your speakers’ power rating should be at least 125W for 8 ohm speakers, and at least 200W for 4 ohm speakers. Do not connect speakers rated at less than 4 ohm.

Note:Amp can drive speakers with nominal impedance above 4 ohms. Two pairs of 8 ohm speakers wired in parallel are also supported. Don’t wire your speakers in series because it will result in poor sound quality.

  1. Remove the cap from the banana plug to reveal the connection hole.

  2. Insert the stripped end of the speaker wire into the hole, then return the cap to the banana plug to secure the connection.

  3. Note:Connect the red (+) and black (-) terminals from each speaker to the corresponding banana plug and terminal 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.

Connect the power cord

Attach the power cord and plug in Amp.

You’ll use our app to set up and control your Sonos system. If you don’t have the Sonos app, download it from your app store. See Controls and lights.

Connect Amp to your TV

Use an HDMI cable to connect Amp to your TV. When connected, Amp creates two front audio channels and plays your TV sound through your favorite non-Sonos speakers.

Note:You may need the optical adapter too (the app lets you know).

  1. Fully insert the HDMI cable into Amp’s HDMI port.

  2. Connect the HDMI cable to your TV. You have two choices:

 

If your TV has an HDMI ARC port

HDMI ARC is a special port that looks like a standard HDMI port. Although they look the same, if you connect to a standard HDMI port, you won’t hear sound.

  1. On your TV’s audio OUT panel, locate the HDMI ARC port.

  2. It may be on the back or side of your TV. Look for the port with “ARC” on the label.

  3. Connect the HDMI cable to the TV’s HDMI ARC port.

Note:If you can’t find a port with the word “ARC” on the label, your TV doesn’t have an HDMI ARC port. See If your TV doesn’t have an HDMI ARC port.

 

If your TV doesn’t have an HDMI ARC port

You’ll need the optical audio adapter.

  1. Remove the protective cap from the optical adapter.

  2. Attach the optical adapter to the HDMI cable.

  3. Connect the optical adapter to the TV’s optical digital OUT port.

Note:The optical adapter’s port is “D-shaped”—make sure the connector aligns correctly into the port. Inserting the adapter incorrectly may damage the cable.

Line-in

Connect an external source like a phono preamp (your turntable may have a built-in phone preamp), or other audio device. Learn more.

Change from stereo to mono

Amp plays audio in stereo by default. You can change the sound settings for the room associated with the Amp so that it plays in two mono channels when playing music.
