I should of notice this when I was practicing at home. The mackie would be cranked to 12 o' clock in stereo mode (300 watts at 8 ohms) and this wasnt all that loud to me. My Eden would be set near clip (the light only going off when I would slap all the strings at once) At the gig to compete with the band I had to crank channel one 4x10 8 ohm(which is what I had going at home) and channel two 1x15 4 ohm to about 3 o' clock. On the mackie forum they are convinced that the problems rest with my pre amp. This is because the mackie wasnt anywhere near clipping. The single leval lights never got above -9. Is this normal?
