Members faidlor Posted July 29, 2010 Members Share Posted July 29, 2010 Hey gentlemen of HC. I am having a problem with my RMX1450 amp and I really hope it is not fried. This evening during rehearsal, we played for about an hour at moderate volume. Mixer master gain at 0db and amp gain at 3 o'clock. The amp feeds into a pair of SF215. After an hour of rehearsing the amp was flashing red lights and sound slowly dies until no sound came out. I shut it off for about five minutes and it would start up again but then 5 mins later it would shut down. Are these amps known for doing this? Would this be a serious case of "thermal shutdown"?

Members Imwithpepe Posted July 29, 2010 Members Share Posted July 29, 2010 Check to see if there is a ton of dust buildup in the fan/vent and inside your amp. Lots of folks will leave an amp rack untouched for months at a time, allowing dust to just build and build. This could cause your amp to overheat. One of those routine maintenance things that sometimes gets overlooked. Link to comment Share on other sites More sharing options...
