How to couple speakers

Short answer

This article covers how to pair Stanmore II Bluetooth speakers for synchronized audio output.

What is coupling and how does it work?

With the coupling feature in the Marshall Bluetooth® app, you can set up two speakers that stand within 1 to 2 meters of each other as a pair.

Coupling is available for Acton II, Acton II Bluetooth, Stanmore II, Stanmore II Bluetooth, and Woburn II Bluetooth.

How to couple two speakers

  • Pair both speakers with your device.

  • Start the Marshall Bluetooth app and ensure the latest version is installed.

  • Select ADD NEW DEVICE and connect both speakers to the app.

  • Choose COUPLE SPEAKER from the main menu and follow the in-app instructions.

  • Select either ambient mode or stereo mode.

  • After completing the speaker coupling, the two coupled speakers will appear as one device in the Bluetooth list. Make sure you remove the unused speaker from the Bluetooth list.

Ambient or stereo mode

You can select either ambient or stereo mode.

Ambient mode: Two speakers play the same audio synchronised. Each speaker plays both the left and right channels. Choose this mode if your speakers are placed at different heights, directions or areas of the room.

Stereo mode: Two speakers of the same size are coupled as a stereo pair. With one speaker on the left channel and the other on the right. Choose this mode if the speakers are placed at the same height, equal distance and facing the same direction.

Compatibility

Due to changes and the availability of components used for the coupling feature, there are some limitations when coupling different models. See the table below to find which models are supported. You can find the speaker model on the back of the speaker.
