Aaron, you really should "know spl levels" if for no other reason than to help prevent hearing loss. If you shut the 1015 down and it wasn't related to a loose wire causing a short, it may be an indication the you were simply using too high a sound level; getting an SPL meter will let you judge this better than simply what your ears indicate. The high powered receivers with clean output of 100 watts or more which are readily available today can result in sound levels which are clean and sound pretty impressive, but which are nevertheless dangerous.
