Select the audio source
Short answer
Switch between different audio sources by either using the source button or the Marshall Bluetooth app.
There are many ways to connect to your Stanmore II Bluetooth Speaker:
Bluetooth: Wireless Bluetooth connection
AUX: 3.5 mm stereo port
RCA: Double RCA inputs (left and right)
Switch between sources in the Marshall Bluetooth app, or follow these steps:
Turn on the speaker.
Push the SOURCE button and toggle between Bluetooth, AUX, and RCA.
The source indicator shows which source is currently selected.
Make sure that the volume is set to low on both the speaker and the audio source before using the speaker.
