Update on the 115 smoking guys...
Was a faulty speaker.
I don't know a lot of the technical side of what was wrong (took my guitarist along to make sure I understood... lol). Anyway, from what I can gather, when it was built, the two wires were placed too close together, and when the speaker moved, they were touching each other, causing the problem of shutting off, and then the smoke after it came back on. Sorry if that doesn't make sense, like I said, I don't know too much about the technical side.
Pro Audio in Canberra replaced with a brand new speaker today, hopefully it will be right now.
Also, I don't think I'm all that loud. :S
I dunno. Maybe I am. I played around alot with the settings today and hopefully it will run slightly better now.
We use a reasonable size PA (two JBL srx 2x18 sub boxes and two 2x15's with horns), so I'll probably be relying on that much more now, and see how I go.
Glad that issue is sorted anyway!
