Marshall INDICADORES-FRONTALES-ROJOS on speaker: mic muted

Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
On the Marshall Uxbridge Voice, red front LED indicators (or orange in the Google Assistant manual) show that the microphones are muted and the voice assistant cannot be activated. Push and hold the microphone button for 2 to 3 seconds until the front indicators turn off.
Safety first
Stop and check this first
- Always unplug the mains lead from the wall socket before disconnecting it from the speaker, and never try to remove the front fret on the Uxbridge because it is not removable and can damage the speaker.
Safe checks you can perform
- Push and hold the microphone button for 2 to 3 seconds
- Unplug mains power from the wall socket for 15 seconds
- Factory reset by holding Volume + and Treble - for 7 seconds
Leave these tasks to a qualified professional
- Do not attempt this professional task: Connect with the Marshall support team without removing the fret

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Push and hold the microphone button for 2 to 3 seconds
- Who:
- you, pressing the microphone button on the top panel of the Uxbridge.
- How:
- push and hold the microphone button for 2 seconds (or 3 seconds as listed in the manual troubleshooting table) until the front LED indicators change from red or orange to off.
- Result that matters:
- unmuting the dual microphone array so Alexa or the Google Assistant can respond again.
- If the front indicators turn off:
- test a voice request with 'Alexa' or 'Hey Google'.
- If the front LEDs stay lit and no controls respond:
- move on to the 15-second power cycle.
- Evidence to keep:
- the state of the front LED indicators before and after holding the microphone button.

Unplug mains power from the wall socket for 15 seconds
- Who:
- you, following Marshall's guide for an unresponsive Uxbridge Voice.
- How:
- always unplug the mains lead from the wall socket first, wait 15 seconds, and plug it back in; on the Google Assistant version, the manual notes that the microphones are unmuted once the speaker restarts.
- Result that matters:
- clearing a software hang without erasing your user settings.
- If the speaker restarts with the front indicators off and answers voice commands:
- issue solved.
- If the unit remains unresponsive after reconnecting power:
- proceed to the 7-second factory reset.
- Evidence to keep:
- whether the front indicators turned off after the 15-second power cycle.

Factory reset by holding Volume + and Treble - for 7 seconds
- Who:
- you, only if the 15-second power cycle did not restore control.
- How:
- push and hold both the upper part of the volume button (+) and the lower part of the treble button (-) for 7 seconds; note that this deletes all user settings and requires setting the speaker up again.
- Result that matters:
- wiping corrupted settings when a software error keeps the speaker unresponsive.
- If the speaker resets and the microphone button toggles the front LEDs normally:
- set it up again in the app.
- If the front indicators or top buttons still fail to respond, open a ticket with the Marshall support team.
- Evidence to keep:
- the outcome of holding Volume (+) and Treble (-) for 7 seconds.

What it means
Marshall's official Uxbridge Voice documentation explains that the front indicators show the mute status: when the microphones are muted, the front indicators turn red (while the Google Assistant edition manual notes orange in its mute section) and Alexa or the Google Assistant cannot be activated. To unmute, Marshall's web guides say to push and hold the microphone button for 2 seconds and the manual troubleshooting tables say 3 seconds, until the front LED indicators turn off. On the Google Assistant model, powering the speaker off also unmutes the microphones on restart. This light state alone never proves a part is faulty.
Warnings and stop conditions

Symptoms and causes
Probable causes · in order
- Microphones muted on the Uxbridge VoiceCommon
Marshall states that if Amazon Alexa or the Google Assistant is not responding to voice commands while the front LEDs are lit red (or orange), the likely cause is that the microphone is muted.
Evidence: Uxbridge with the Google Assistant - User Manual · Support for Uxbridge voice with Amazon Alexa - How to mute and unmute the microphone | Marshall.com · Support for Uxbridge voice with Amazon Alexa - Troubleshooting : Alexa is not responding | Marshall.com
- Microphone button not held for the full 2 to 3 secondsPossible
Tapping the button briefly may not toggle mute: Marshall's web support specifies holding the microphone button for 2 seconds, and the manual troubleshooting table specifies 3 seconds, until the LEDs turn off.

- Software error leaving the speaker unresponsiveLess common
If the speaker does not respond to button presses at all, Marshall attributes it to a software problem that requires unplugging mains power for 15 seconds or performing a 7-second factory reset.
