System Message
Update error
Displayed if the rmware update has failed. Try to restart the unit. If the issue persists,
check that each L-NET cable is in working order and is correctly plugged on both
ends, and relaunch the update process. If the issue persists, contact L-Acoustics.
High temp on ch #
Channel attenuated
Displayed if temperature at an output channel is above 60° C. The signal delivered
at the output channel is attenuated until temperature returns to nominal conditions.
Over temp on ch #
Channel muted
Displayed if temperature at an output channel is above 65° C. The signal delivered
at this output channel is muted until the temperature returns to nominal conditions.
System Message
Fan blocked
Displayed if a fan is faulty. The unit remains operational but there is a risk of
temperature rising.
Speaker fault on ch #
Channel muted
Displayed if the unit detects a short-circuit fault in the speaker coil of the connected
enclosure. The output channel is muted to avoid a potential risk of physical harm
and further damages to the product. Verify the connected loudspeaker enclosures.
Disconnect or replace the faulty enclosure, then unmute the output channel.
For temperature-related messages
possible cause diagnosis / procedure
room temperature is too high / too low
Make sure room temperature is within amplied controller
operating condition range (0º C / 32º F to +50º C / 122º F).
foam lter clogged, inside of amplied controller dusty Clean or replace the foam lter, clean the amplied controller
with an air blower.
amplied controller is not getting enough cool air
Install the amplied controller in an open area so that the front
and rear panels are not blocked by an external objects or
structure.
If rack-mounted:
• Do not block the ventilation grill with front and back
panels or doors, or use a forced ventilation system.
• When stacking more than one amplied controller, mount
them directly on top of one another or close the free
spaces with blank panels.
channel resources are solicited to their limits
Monitor the channel LED meter:
In case of persistent high level or clip, reduce the audio source
output level (refer to the third-party documentations) or the
gain value on the channel.
loudspeaker impedance too low
Check that nothing causes a short-circuit at the output
(incorrect cabling scheme, damaged cable or short-circuit in
the speaker voice coil).
