      If you're experiencing low or no audio from your MARSHELL Speakers, there might be a few reasons. First, ensure the correct audio source is selected using the source button. Secondly, verify that your audio device is properly connected to the speaker. Finally, check the volume levels on both your audio source and the speaker, and increase them slightly if needed.

    Why is the audio distorted on my MARSHELL ACTON III Speakers?
    • N
      Nicole DixonAug 7, 2025
      Audio distortion on your MARSHELL Speakers can occur if the volume is set too high on the audio source. Try turning down the playback volume on your device. Alternatively, the volume, bass, or treble settings on the speaker itself might be too high. Lower these settings to see if it resolves the distortion.

      If your MARSHELL Speakers aren't turning on, the most likely cause is that they are not connected to a power source. To resolve this, connect the mains lead to the speaker and ensure it's plugged into a working wall socket.
