I'm pretty sure the answer is no. I've also been looking for this, but not found it.

Once when I had people home, and we might have been drinking a little too much, one of the guests started to increase the volume pretty fast. That costed me three tweeters for my Revel speakers. My G68ADV was set to Trifield.

Later I had a friend home to help with settings for my subwoofer etc. He measured the outputs and found that above 0 (87) my G68 starts clipping, sending out a square wave. I assume it was this that killed my tweeters, I don't know if this is normal, or something wrong with my G68.
