How do I resolve a “System Message Update error” on my L-Acoustics LA4X?
If you encounter a “System Message Update error” on your L-Acoustics Controller, it indicates a firmware update failure. First, restart the controller. If the issue persists, verify that each L-NET cable works and is correctly plugged on both ends. Then, download the firmware again and re-launch the update process.
What does “Error on Channel x Channel Muted” mean on my L-Acoustics LA4X Controller and how to fix it?
The “Error on Channel x Channel Muted” message on your L-Acoustics Controller indicates a short-circuit in the loudspeaker or loudspeaker cable. To resolve this, verify that there are no issues causing a short-circuit at the controller outputs, such as a wrong cabling scheme, damaged cable, or a short-circuit in the speaker voice coil. After checking, restart the controller.
What causes a grey screen on my L-Acoustics LA4X Controller?
If your L-Acoustics Controller LCD screen is lit but nothing is displayed (grey screen), the issue might stem from: * The controller being connected to a non-compatible network. Disconnect all cables from the L-NET connectors and restart the controller. * Condensing humidity inside the LCD screen. Place the controller in a non-condensing environment and allow the LCD screen to dry.
What does it mean if the LCD screen on my L-Acoustics LA4X is lit but dark?
