HF error on ch #
Channel muted
Displayed if energy above 25 kHz is detected at an output channel. The channel is
muted for 2.5 seconds. Make sure the latest preset is being used. Contact your L-
Acoustics representative for advice.
System Message
Update error
Displayed if the rmware update has failed. Try to restart the amplied controller. 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 90° 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 96° 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 controller remains operational but there is a risk of
temperature rising.
System Message
SMPS high temp warning
Displayed if SMPS temperature reaches 75° C. The controller remains operational
but temperature should be monitored.
System Message
SMPS over temp error
Displayed if SMPS temperature reaches 80° C and above. The SMPS initiates a fast
restart.
System Message
SMPS low temp warning
Displayed if SMPS temperature reaches -15° C. The controller remains operational
but temperature should be monitored.
System Message
SMPS under temp error
Displayed if SMPS temperature reaches -20° C and lower. The SMPS initiates a fast
restart.
Module high temp on ch #
Channel muted
Displayed if temperature at an output channel reaches 97° C. The channel is muted
for 2.5 seconds.
Module over temp on ch #
Channel disabled
Displayed if temperature at an output channel reaches 102° C and above. The SMPS
initiates an emergency shut down for safety. Reboot is required.
For temperature messages:
possible cause
diagnosis / procedure
room temperature is too high / too low
make sure room temperature is within amplied controller
operating condition range (0º C / 32º F to +50º C / 122º
F)
foam lter clogged
clean or replace the foam lter
amplied controller is not getting enough cool air
install the amplied 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 amplied 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).
