Setting Up the Stanmore II

Configure the speaker with the Marshall Bluetooth® app to get the most out of it. The app is available from the App Store and Google Play.

1. Download the Marshall Bluetooth® app and follow the in-app instructions.

Icons for the App Store and Google Play are displayed, with text indicating where to download the app.

Selecting Audio Source

There are several ways to connect to your Stanmore II:

• Wireless Bluetooth Connection
• AUX - 3.5 mm Stereo Jack
• RCA - Double RCA (Left and Right) Jacks

1. Push the Source button to toggle between Bluetooth, AUX, and RCA audio sources.
2. A lit indicator shows which source is selected.

The source can also be selected from the Marshall Bluetooth® app.

Caution: Make sure that the volume is set to low on both the speaker and the audio source before using the speaker.

Diagrams show the source button being used to change the input source.

Connecting via Bluetooth (Pairing)

1. Select Bluetooth as the input. Pushing the Source button toggles the input sources.
2. Push and hold the Source button for 2 seconds. The Bluetooth indicator starts to blink.
3. Enable Bluetooth on your device (smartphone, tablet, computer).
4. Select "Stanmore II" from the Bluetooth list and accept pairing. The Bluetooth indicator on the speaker stops blinking and remains lit when the units are connected.

Stanmore II can be connected to two Bluetooth devices at the same time. Playing a connected Bluetooth device will make it the selected audio source, pausing any previously played audio on the second device.

Diagrams illustrate the pairing process, showing the speaker's Bluetooth indicator blinking and a phone selecting "Stanmore II" from a list.

Connecting via Aux Input

• 001. Single-click to either play or pause.
• 002. Double-click to skip forward.
• 003. Triple-click to skip back.

Note: Playback can also be controlled from the Marshall Bluetooth® app.

Diagrams illustrate the single, double, and triple clicks on the play/pause button.

Couple Speakers

Two Acton II, Stanmore II or Woburn II speakers can be coupled to act as one sound system. There are two modes to choose from:

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

1. To couple two speakers, open the Marshall Bluetooth® app and connect to your speakers.
2. Go to "Couple Speakers" and follow the in-app instruction.

Diagrams show the speaker setup for Ambient Mode and Stereo Mode. Another diagram shows a phone connecting to the speaker and a numbered list for pairing.

Note: Make sure your audio device is only connected via Bluetooth to one speaker when playing on coupled speakers.

Standby Mode

If the Stanmore II is left unused for 20 minutes, the speaker goes into standby to save energy. In this mode, all indicators are off.

1. Interact with any button or knob on the top panel to wake the speaker up from standby mode.

Note: The speaker can also be woken from the Marshall Bluetooth® app.
