If the loudspeaker is plugged in, and the switch is on,
but no LEDs illuminate, check the following:
• Make sure the power cord is fully and securely inserted
in the IEC receptacle and in the wall outlet.
• Confirm that the AC outlet is "live, " using a tester or other
device (such as a lamp) that is known to be working.
• If the loudspeaker still shows no power, it is possible that the
internal fuse may have opened. This is not a user-serviceable part.
Contact PreSonus technical support for more information.
Check to make sure the signal is "live" from an external source. Check that output
faders are up on the mixing console and check the output level using headphones.
If another speaker in a stereo configuration is working, swap input
cables. If the problem moves, replace the faulty cable.
If the loudspeaker has been producing sound at high levels and
then stops, it may have gone into thermal muting. Allow the unit to
cool, and make sure the heat sink has sufficient ventilation.
Check the input sources, using headphones, if possible,
to determine if the problem is with the source.
Check console outputs and all input and loop-thru connectors to make sure they
are securely plugged in. If the problem persists, try replacing cables with spares.
Check the input sources, using headphones, if possible, to
make sure the signal is not already distorted.
Check the clip indicator on the rear panel or in SL Room Control monitoring.
If the LED is lit all or most of the time, reduce the input levels.
