At tonight's gig i was using my stewart 2.1, both channels driven as usual. At about 12:30 i was messing with the preamp and hit a low E with a ton of bass boost. There is a compressor in between the preamp and the stewart and it squashed the signal pretty hard but one channel shut down. (both channels were at about 10 o clock input gain on the stewart, one was driving 4 ohms, the other one which shut down was driving 8 ohms) I checked the back and the individual fuses hadnt blown. The channel never came back on after that. Fortunately the 2 channels of the stewart are completely seperate so i was able to keep on playing. I was also able to combine the cabinets for a 2.7 ohm load for the rest of the night with no problems. Anyone else have this happen? and what do ya think got fried? I'll find out for myself soon, but i figure someone might know.
