Set up your Sonos Port

  • Mobile device required

This article will guide you through setting up your Sonos Port. You can find more information on product features and specs on Port's product page.

Before you start

  • Place your Port in your desired location and connect it to power.

  • Port’s small form factor allows three units to sit side by side on a standard 1U rack shelf. When stacking multiple Ports, it can result in WiFi interference and increased operating temp. Make sure there is proper ventilation and that Port does not exceed 104ºF (40ºC). If the Ports experience WiFi trouble, move them or wire them to the network.

  • Download the Sonos app for iOS or Android. The app will guide you through the set up process.

Connecting Port's audio inputs and outputs

Audio inputs

Port has a set of analog RCA inputs that allow you to connect devices like turntables or CD players. Simply connect the RCA cable from your external audio device to Port’s RCA inputs labeled IN. To learn more, check our article for using line-in on Sonos.

Audio outputs

Before playing music, make sure your amplifier or receiver is set to the input that Port is connected to. If you experience issues getting audio after following these steps, use our article for troubleshooting no sound from Port for some additional help.


Connect one end of the RCA cable to the Port’s RCA outputs labeled OUT and connect the other end to an RCA input on your amplifier or receiver.

Digital Coax

Connect one end of a digital coax cable to the Port’s output labeled DIGITAL OUT and connect the other end to a digital coax input on your amplifier or receiver.

12V trigger

Port has a 12V trigger output with a current rating of 200mA that can be connected to an amplifier with a 12V trigger input. This brings an amplifier out of standby mode when music starts playing, reducing the time it takes for the amplifier to become active and start outputting audio to your speakers.

Line-Out Levels

You can change the way you control the volume of your Port using the Line-Out Level settings.

  1. Open the Sonos app for iOS or Android.
  2. From the  Settings tab, tap System.
  3. Select the room with your Port or Connect.
  4. Tap Line-Out Levels and choose one of the options.


Set Port’s line-out level to Fixed if you want to control the volume exclusively from your amplifier or receiver. You won’t be able to use the Sonos app to adjust the volume or equalization settings.


When Port’s line-out level is set to Variable, you can use the Sonos app to adjust the volume.


When Port’s line-out level is set to Pass-Through, Port stays at a fixed volume and sends volume commands to amplifiers that support pass-through. You can control volume using the Sonos app, a universal remote, or your voice if you have a voice assistant enabled.
