Corrective maintenance
USB ports stopped working.
• Check that the connected devices do not draw more than 900 mA / 5 V. If at least one device does, disconnect it,
and power cycle the processor.
• Contact L-Acoustics.
Network issues
Impossible to connect a processor to the L-ISA Controller network.
Refer to the
L-ISA Controller
help for software use.
possible cause
diagnosis/procedure
processor is set with an incorrect IP address
set the processor IP address in L-ISA Controller
several devices (processors or amplied
controllers) are set with the same IP address
connect the processor to the computer running L-ISA Controller and set
the processor IP address in L-ISA Controller
network cable is not plugged or incorrectly
plugged
plug and secure CAT5e U/FTP cables into the AVB or CONTROL
connectors on the processor to connect it to other processors, to
amplied controllers, to the computer, or to Ethernet switches
Refer to
(p.21) for network topology.
network cable is damaged
replace any damaged CAT5e U/FTP cables in the network chain
more than two software clients are already
connected to the processor
disconnect all other software clients
rmware failure
restart the processor
other causes
contact L-Acoustics
Sound issues
No sound
possible cause
diagnosis/procedure
mains failure
inspect the mains
inputs/outputs are muted
unmute the inputs/outputs
gain value is too low
set an appropriate ouput gain value
If there are fallbacks enabled, set an appropriate input gain value.
incorrect source selection
check the matrix mixer and routing, and input and output MADI and
AVB mapping
If there are fallbacks enabled: select another source that is not reserved
for fallback, or disable fallback on the source.
audio source is not plugged, incorrectly
plugged, or plugged into the wrong input
connector
(re)plug and secure each cable into the audio source and the
corresponding input connector on the processor
audio source cable is damaged
replace the cable
incorrect settings on the audio source
set appropriate parameter values on the audio source, in particular the
output gain value (refer to the third-party documentation)
non-audible bit stream
check that the MADI or AES/EBU source does not deliver non-audio bit
stream (encoded audio)
no AVB input stream
check that a talker is connected to the processor by using an AVDECC
controller
