Yesterday, I had to stay after school to set up the PA system... The Sub Power Amp had broken, and we had just gotten it back... I'm hooking it all up, and when I try to get the speakon into the power amp, it won't go in no matter what way I try it... then I finally get it in... yay. Then today, I hook up the subs, they are working... then I hook up the tower speakers, they don't work. I'm like "OMG ***?" and then my band teacher was like "Feex it, fgot n00b." So i try.. and it wont. Then he comes and looks at it, and apparently I managed to get the speakons into the power amp.... upside down. And now we cannot get them out. Apparently I was doing such a good job at not paying attention, that I defied the laws of physics.
