Common Lake Controller errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact software is in Ask Roadie.
- Step-by-step fixGet the fix →
Amp reports Mains Fault
Likely cause: The PSU monitors incoming mains and faults out to protect itself when the supply is out of spec.
- Step-by-step fixGet the fix →
Amp shows NEEDS SERVICE:4 or DICO COMM FAULT for no clear reason
Likely cause: A firmware bug tripped an internal DICO/service fault falsely; the fixed firmware corrects the state logic.
- Step-by-step fixGet the fix →
Analog input/output hum or ground loop
Likely cause: Iso-Float electrically isolates the analog reference so a ground-potential difference no longer drives hum current through the signal.
- Step-by-step fixGet the fix →
Channel LED steady red with VHF FAULT
Likely cause: A dedicated VHF detector mutes the channel to protect compression drivers from sustained ultrasonic energy.

How do I update firmware on a PLM/D or LM device?
Likely cause: LakeUpdate flashes the frame firmware to the version bundled with the installed Controller; interrupting power can brick the module.
- Step-by-step fixGet the fix →
How to set Dante network redundancy on LM/LMX
Likely cause: Dual Redundancy carries the same Dante flow on two isolated networks so a cable/switch failure switches over without audio interruption.
- Step-by-step fixGet the fix →
Lake Controller opens but Frames will not appear even on the same subnet
Likely cause: Lake discovery/control traffic is blocked by the firewall or sent out the wrong NIC; allowing both profiles and binding the right adapter restores discovery.
- Step-by-step fixGet the fix →
Old firmware notification / frame will not come fully online after a Controller upgrade
Likely cause: The Controller refuses full control of a frame whose firmware protocol differs; matching versions restores it.
- Step-by-step fixGet the fix →
Recall a whole system to a known state
Likely cause: System files snapshot every module and group so a full rig returns to a verified state in one recall.
- Step-by-step fixGet the fix →
TEMP WARN:CH or TEMP FLT:PSU over-temperature
Likely cause: The amp derates then mutes to protect the output stage/PSU from thermal damage; restoring cooling clears it.
- Step-by-step fixGet the fix →
Which Lake Controller version / firmware should I run?
Likely cause: Controller and device firmware are versioned together; a mismatch shows frames offline or partly-standby.
