I've programmed for 5 hours KPA rigs and played and then a sudden stillness.
The input LED is dark. In Tuner mode, no more rash, the bubble in the water level is very quiet in the middle, although I have at the entrance of the KPA now the radio station (Line 6 Relay 50) swapped the cable and also tried a different guitar. Even the touch of the guitar cable in the input does not help to "light up"
System reset with no success, no input LED is lit, no tuner function.
Device switched off and switched on about 20 minutes later and now everything works again.
What could be the cause of the catastrophic failure, I have shortly the next gig with the KPA ... and I am very worried ...
best regards
