I just wanted to let anyone on the pro audio side that I had a pretty bad failure the other night.. Just to set the scene, I was using one fp10q clone, plugged into a 15 amp circuit ( supplied by a motion labs stinger on 25 ft of 10/4 with a dryer plug to 30 amps adapter) it was running one yorkville tx-9sub per channel. (2x18", 4 ohm cabinets) Our band is all electronic ( kit, bass direct , guitars direct) and we're all on In ear monitors. No stage volume so the pa can stay relatively low. Anyway first two songs we start to lose the bottom end, the amp was shutting off for 20 seconds, then old return for a few beats then shut down again. I'll have to check the dip switch settings, but I don't believe the fp10000 is up for doing pro audio reinforcement. I repatched and used two crown xls2500 for the rest of the night without issue... This amp is going back in my monitor amp rack for lighter duty, I'll probably list all 4 of mine for sale in the fall , end of September ( no I'm not giving them away, but I will deal especially if you buy more than one.).
