Bob raises a good point. I sometimes perform to a backing track I create and am stuck with the house mono PA. So, I have a Mono button on my Presonus Central Station (speaker controller) to test my mix in mono. If you do the wrong thing in mixing, it's possible to have a signal on the left and right cancel each other and disappear in mono. You would never know it by testing the mix with regular stereo monitors or especially headphones.
