was running my k10's today in the spare room whislt doing my latest demo cd and suddenly one started cutting out, i wasnt running them hard infact far from it the mixer was running on about -22 db and the channel gain was running -4db

the blue power led on the front kept going off then on again the music would start again?

looking at the rear pannel on the affected speaker
blue power light would be on
fan cuts in
limit light comes on
green power light comes on
then back to blue power light
music starts again
ive tried swapping xlr's and power leads and swapping channels on the mixer and also trying both channels a and b on the speaker itself gain set to 0db gain. :( :( :(

Sounds like theres a serious bias fault causing the output stage to overheat..
( fan comes on ) then amp shuts down as its over temperature cools down and it all starts again.
You need an aproved QSC dealer are they still under warranty?

Seem to remember ringing em last time i had a Dead QSC Amp in
