Introduction

Passez à l'étape 1

This guide is intended to replace the auxiliary input assembly in the Marshall Stanmore II Bluetooth Speaker.

The AUX input allows a device to play audio through the speaker via an auxiliary cable. This is especially useful for devices that may not be compatible with the speaker's Bluetooth capabilities. Without AUX input, a user may be limited to only using devices that support Bluetooth or RCA, which cannot be found on some older devices such as desktops, laptops, or portable media players.

Before using this guide, verify the source selected for the speaker is set to AUX. This is indicated by a white light next to the AUX option on the upper panel of the speaker. Push the button labeled SOURCE to toggle between options until AUX is illuminated. Next, ensure that the volume of both the speaker and device are set to a comfortable level. Sometimes when the device volume is too low, the speaker may not detect any audio input. If these methods don't fix the issue, follow the troubleshooting steps on the Marshall Stanmore II Bluetooth Speaker Troubleshooting page for more solutions before disassembling.

Turn the speaker around with the knobs facing you and unscrew the threaded washer that secures the AUX module to the outer plate.

Since it is disconnected from inside the frame, the AUX board may loosen enough to fall after removing the washer.
